Other Coating Resins

More specilised coating resin used include polyurethane, neoprene, hypalon, silicon rubber, butyl rubber and florinated rubbers and polymers such as Viton and Teflon. These materials are all more expensive than PVC, in some cases much more expensive, but have particular end uses where they are quite superior to PVC in chemical resistance (or other properties).

Polyurethane has better chemical resistance than PVC, bonds well to basecloths, and is drycleanable when used for protective clothing. It is subject to hydolysis with age.

Neoprene (chloroprene rubber) is resistant to numerous types of acids, alchol compounds and solutions.

Hypalon (sulphochlorinated polyethylene) provides better chemical resistance than PVC, including resistance to hydrogen fluride.

Butyl (isobutene - isopropene rubber) is particularly resistant to concentrated acetic acid, acetate and furol.

Viton fluoroelastomer (copolymer of hexafluorpropylene and vinylidenefluoride) is particularly resistant to halogens, concentrated mineral acids,chlorinated solutions and even toluene.

Teflon (polytetrafluorethylene) is probably the most chemical resistant material knon, but is very expensive and difficult to work.
