Inferior Acrylic Resins?

[rwwoods]

One internet site discounts using acrylic sealers from paint stores and DIY stores because their products use "inferior" acrylic resins. Yet, I can find no reliable information to back up that claim. Is this just a marketing ploy, miss-information, or is there really some acrylic resins that perform significantly better than others? If some perform better than others, how can one tell that a particular product uses a "better" acrylic resin?

Resins manufactured with higher quality raw materials will perform better than resins manufactured with lesser quality raw materials. There are also other factors to take into account, like solids, acrylic properties (poly functional, polyurethane, polymer emulsion, high dispersion) etc etc. I am not a chemist nor do I have the time, so I cannot go into detail about these individually, sorry.

Here is a great read on acrylic resins

There are definitely acrylics that perform better than others. Most liquid paints sold in big box stares are not high quality products. You would need to read the product data sheet and compare performance criteria.

Do you have a specific question?

Thanks for your reply. When you say "criteria" are you referring to industry standards, such as ASTM, that may be referenced in the technical data sheets? If so, there seems to be a disparity between vendors in the standards listed. Are there one or two particular standards one should look for as a sign of a better product?

Yep, that is what I am referring to. There are thousands of ASTM standards for nearly every industry out there. There are different methods of testing too.

I have uploaded a Product Data Sheet and Performance Criteria of one of our products. Hopefully you'll be able to use this to compare to other products to get an idea of what you're looking for.

I should mention, this is not a flooring product. This is usually used on exterior structural and architectural steel. Store fronts, water tanks, piping, fencing etc etc.
