I received another sample from Line-X, out of the blue, yesterday. I have 2 samples I can send to ya, if you need them... they're oval's, about 4" long x 1.5" wide.

Below is the info previously posted by Brewmaster regarding spray-on liners. Let's keep this thread on track and reserve it for Brew's testing results.

I do have results for Diamond Liner (their HQ is near my house and they gave me a huge sample without any hassle) and Rhino.

Here is the first round of results:

Rhino Liner

Hardness: 77 Shore A
Tensile Strength: 1162 psi
Elongation: 182%
Modulus at 50% Elongation: 541 psi
Modulus at 100% Elongation: 795 psi

Taber Abrasion Test Score: .6264 (mg loss/revolution)


Diamond Liner

Hardness: 87 Shore A
Tensile Strength: 2425 psi
Elongation: 223%
Modulus at 50% Elongation: 1030 psi
Modulus at 100% Elongation: 1357 psi

Taber Abrasion Test Score: .4895 (mg loss/revolution)

Explanation of Tests and Scores

The tension properties (tensile strength, elongation, and modulii) are attained by taking a strip of the sample (ASTM D412 in case anyone cares) and pulling it until it breaks using and Instron tensile tester.

Tensile strength is how strong the material is at break. Basically, how hard you have to pull on it to make it break. It is in psi so it doesn't matter how thick the sample is (within reason of course).

Elongation is how much (in %) a one-inch section of the strip stretches when pulled at a constant speed of 20 in./min. The higher the elongation, the more resistant the material is to breaking when stressed (like when you drop bricks on a bedliner).

Modulus at 50% or 100% means how strong the material is at a certain elongation, in this case either 50% or 100%. It is basically the tensile strength at those points of elongation. Since most materials are no good once they break (tensile strength reported above) we look at the modulus at certain points before it breaks. Again, the higher, the better for this kind of application.

Taber Abrasion Test Score is measured in milligrams of material lost (or abraded) per revolution. A 4 inch in diameter circle of each material is attached to a spinning wheel. two other coarse stone spinning wheels are placed perpendicular to the material and abrade the surface away as the test material spins. the wheels are like those very rough grey heads you can buy for a Dremel. i did 1000 revolutions because these types of materials are not too abrasion resistant compared to rubber. (I have compounds at my company that have scores of .0400 at 5000 revolutions, a much tougher test). all you need to know is the lower the number, the more resistant the material is to abrasion.

so, my opinion as a materials expert and a truck owner is that I would not buy a Rhino Liner, I would go with Diamond Liner. Diamond Liner is twice as strong as Rhino and has better abrasion resitance. but, Line-X and Armorthane have not weighed in on my tests, so I would not run out to get a Diamond Liner just yet.

I think this is also why Rhino sprays twice as thick a everyone else(.250"). in my opinion, I would say "big deal" the material is still not all that good, no matter how thick you spray it. not to mention that most spray in bedliners end up adding 50-70lbs of weight to your truck (hard to believe, but it's true), so I would not want it coated thicker with an inferior material. it would add more weight to get, perhaps, the same protection as the lighter liners. i will post back in this thread my next set of results as soon as the Line-X and Armorthane samples get here.

Cheers.

EDIT: I forgot to report the hardness, so I just put it in above. It is pretty self explanatory, the higher the number, the harder the material. Shore A is just the scale used. I report it since there are several hardness scales. Harder is better in this applicaiton.

 

sorry wingn8ive, those sample would be too small. no worries, Line-X is sending the samples. The armorthane samples should be here early next week.

with these results, it may be worth making a sticky or perhaps an F150online review of the products. i don't know how F150online handles endorsing a prodcut, but i think a product review that is available later on (not just in a thread on the 04 F150 forum) would be good for people asking these same questions about bedliner materials. i'd be happy to write a review and list some tips for buyers of these kidns of materials, sort of what I have put in other threads. webmaster if you're interested in doing this or having me do it, or if you just want to tell me to shut the hell up and stop making lame suggestions like this, shoot me an email.


cheers.

 

You guys are great for doing this test. I bet there are a lot of folks hinging their decision on your results. What a great web site.

 

wingn8ive,


I am sorry that you have been unable to acquire some samples of Line-X I would be more than happy to supply you with some samples of our product. I am glad to see that you are doing more than just research for the consumer. “An educated consumer is the best kind of consumer.” I like to see that people are educating themselves in the spray-on polyurethane industry. The only concern I have about this testing is there is no thickness properties test; the properties do change over .125mils for a polyurethane/urea hybrid or poly-urea. “wingn8ive” the test on the Diamond Liner Brand Spray-On Bedliner was done with there industrial grade poly-urea not there polyurethane urea-hybrid, that is used for the spray-on bedliners. This alone would be enough to say that this test is misleading for any consumer. As much as I would like to say that I dislike my competitors you have to at least give a level playing field for Rhino and alike. Most companies have two types of polyurethanes one is used for industrial Like Line-X XS-350 or Rhino Linings Inc. Tuff Stuff, like most manufactures of Raw Polyurethanes and Poly-urea’s have two different types of High Pressure Poly-urea’s/urethanes the one tested here on this forum was a poly-urea or and “Industrial Grade Poly-urea.” Since DOW has closed another ISO manufacturing plant, there has been a significant price increase all across the board for polyurethanes and Urea’s. It is no longer Economical to the consumer to have sprayed 100% Poly-urea. The cost difference on poly-urea’s vs. urethane hybrids is a 20-28% price hike. Line-X is the largest buyer of polyurethanes in the US and I know that we can not spray 100% urea on a truck bed for less that $310 our cost at 1/8th (.125) inch thick. That is why most companies that use poly-urea like on the Nissan Titan is less than a 16th (.0625) of an inch thick. I know this to be true the specs in which you have posted is for a 100% Urea @ .125 and seeing that Line-X corp. has the most buying power for the raw chemicals I find it highly unlikely and even not probable that they can supply a high pressure poly-urea putting out .125 and sell it for anywhere close to what the market will allow. To have an accurate test I would recommend that you wait until the Diamond Liner or Rhino Linings Inc. or Line-X has sprayed a truck then go over to the truck with an ElcoMeter and test the thickness on the floor of the truck in three points than average to get a total thickness then ask for a sample at that thickness, this would give you an accurate test. As a chemist you have to take into consideration the variables that play a major role of any test. If you like I would be glade to send you a sample of our XS-350 at 1’x1’ and that would put everything to shame. In order for this test to be accurate I think that you would have to take into consideration the many variables that are at play in a very sensitive market. A sample acquired the same thickness as an actual truck bed would have been sprayed would make this an accurate test. If indeed they are spraying 100% Poly-urea, although in some cases” Thicker does not mean better,” this is something that I have been stressing for years to customers. I like to give people analogies to help them understand the differences in products between Rhino Linings Inc. & Line-X. I like to say that if you where a man of uniform and you put 2 feet of foam down your shirt and had someone shoot at you would the bullet penetrate the foam? Now if you had 1/8 inch of Kevlar strapped to your chest would the bullet penetrate the Kevlar? Thickness is all relative to the product strength. Over the years I have found the flexibility of a product not to be the issue as it is in the hardness test. I would have to say that what matters the most is the applicators business sense. Most all spray-on bedliner companies thrive off of referral system if one person’s liner fails and the applicator is not willing to fix this becomes a bad referral or “Bad Marketing.” I can not speak for the Line-X company but who I can speak for is our Line-X franchise. Most companies now are offering a “Life Time Warrantee,” What they forget to mention is that the warrantee is limited. This Warrantee that is offered only covers manufacture defects, bubbling, pealing, and cracking. For most good applicators might only see one-three warrantee fixes a year, “That are actually covered by your warrantee.” It is up to the applicator to deicide abuse, I have seen many cases from all companies that I thought to myself; “That would take five minuets to fix” instead they were turned away and told it would not be covered. If you would like the liner to be fixed it would cost $25-$30. That is when we came up with the, we will fix anything short of you rolling or catching your truck on fire! We figure it is better to have the best customer support after the money is already exchanged hands. As you can see most companies put some sort of tag inside your bed for advertising purposes. I would have to say that is anyone’s best advertisement so why not makes it look good. If your liner is chipped or gouged the person walking by your truck when your not there is not going to think "how you got the gouge or chip." The first thing in the consumers mind is "that the bedliner has failed." "I love this site," it allows everyone the chance to speak and although you might find my testing method unpractical you will find that it is the only way to give any test true validity and provide the consumer with the most accurate information. The true test is picking a company and having no problems, or if you do how that company responds. I figure if I don’t get you on this truck “maybe the next one,” everything is worth a try including non name brand companies but me being bias I would have to say I like Line-X better but that is just because I have the great chance to deal with the customers and the product of Line-X San Diego...

F150online.com post of the week!

My brain hurts:o

 

Good God thats a Book

 

I think i just blew my brain gasket.

 

I couldn't bring myself to read it, did I miss anything important? Doesn't really matter, got my Line X a couple months ago. Best $325 I've spent in a long time.

 

$325 thats a deal WOW!!!

 

It was with a military discount, but yes it was an awesome deal.
