Scratch Resistant Clear Coating for PVC

04/02/2007 2:26 AM

I am looking for a coating I can apply, by whatever method necessary, to a solid PVC floor we produce, to prevent scratching and reduce wear of the printed PVC design on the floor. I have heard of a UV coating, but I am not sure this is the best solution. I would appreciate comments from those familiar with extruded PVC. We are trying to make the surface more scratch resistant. Thanks

Ask a flooring rep to visit and pump him/her for info. Plenty of coatings are made but pvc is a poor choice to start with. It is easily stained and soft by nature. You may need to bond an over coat to it so as to reduce wear and scratching.

Brainwave, thanks for your reply PVC may not be the best choice because it is somewhat soft. But we do put additives in mix to harden it. However it has certain properties,ie waterproof and mold resistant. We are trying to keep surface from scratching easily.

Thanks for your reply. Do you think that this product will adhere and not peel from a PVC surface? What if the surface is on a floor and people will walk on it. Will it work in that environment? Do you make product in USA or out of country? If you think product is applicable, please give me name of a person to contact. Thanks RStanley

Sheild Products fluoropolymer acrylic looks interesting, but standard acrylic polyurethane floor finishes are possibly lower cost (made in vast quantities) and sold everywhere. The stuff is tough if properly installed & cured.

The wear-layer on cork flooring is apparently a polyurethane acrylic, and holds up well on a soft flooring: I've seen stores done in it (albeit rarely) in Canada, and I've heard claims polyurethane coated cork flooring is used in Europe in shopping malls, an airport terminal in Scandanavia, & the Library of Congress (can anyone confirm?). It is certainly sold for commercial flooring applications.

Extruded PVC is certainly subject to UV breakdown, but I somehow doubt UV is your biggest problem if the installation is indoors.

You are right, in fact we have an AC4 coating over printed surface and a UV coating over that. It is the fact that these coating do not get hard enough and easily be cut with knife or sharp instruments. We recognize we cant complely elimante this problem. But we feel it shoud take a little more strengt in order to scratch the floor.

Just send you below mail, it seems this link is not complete.

You have to click further on "PVC plastisol processing" then under applications on flour coverings.

AT the power plant where I work, the concrete floors have just been painted with a 2 part epoxy paint that was applied in two 25 mil thick coats. Once cured, it is extremely hard and appears to resist equipment traffic without scratching or maring in any way .

Try this...

This stuff is used to harden optics, medical devices, and consumer plastics. It cures I think at 150C. be sure to check out the press releases.

There are several types of coatings that can be applied over PVC flooring, depending on what form of coating you wish to use (water based, solvent based, UV curable), whether this is for a single floor or a production line, and the equipment available.

Applied UV curing films, preferably acrylic-polyurethanes, are often the most versatile, but also the most expensive. The UV lamps and associated coating equipment are very expensive. Personal must be protected against the intense UV radiation.

There are both water dispersions and solvent based solution coatings of decent scratch and wear resistant polyurethane coatings. (I would suggest avoiding the "oil modified" polyurethane coatings, as they are not very scratch resistant). These coatings can be applied with a Lamb's wool applicator, etc for small jobs, or flow- coated on a production line. The polyurethanes combine scratch resistance with hardness and flexability, plus excellent adhesion to most substrates. You can test-apply such a coating to a piece of the PVC flooring, if you are unsure of the plasticizer and amount used to make the PVC.

Dear Associate, I have just seen your reply regarding the scratch resistant coating for PVC flooring. Can you direct me to a manufacturer of these coatings? Is there a chance this coating will peel from the PVC surface? The application will be on a production line. Thanks, RStanley
