15 Jun 1993TL;DR: A laminate has at least two layers, at least one of which comprises a polymer having more than one perfluorocyclobutane group as discussed by the authors, which impart qualities of enviornmental or protection, chemical and solvent resistance, hydrolytic stability, lubricity, low dielectric, hydrostatic stability, weatherability and flame resistance.
Abstract: A laminate has at least two layers, at least one of which comprises a polymer having more than one perfluorocyclobutane group. Such polymers impart qualities of enviornmental or protection, chemical and solvent resistance, hydrolytic stability, lubricity, low dielectric, hydrostatic stability, weatherability, flame resistance, chemical resistance, hydrolytic stability, lubricity, environmental protection, scratch resistance, solvent resistance, surface passivation, water repellancy, lower surface refractive index, lower surface coefficient of friction, fluid barrier properties, oil repellancy, thermal stability, and/or reduced moisture pick-up. Additionally, the coatings are optically clear, easy to apply either neat, in a solvent or otherwise, have relatively low cure temperatures for their temperature resistance, and exhibit insulating and planarizing capabilities.

TL;DR: Waterborne epoxy/amine coatings, compared to solvent-based, show considerably lower chemical resistance as discussed by the authors, which is often blamed on hydrophilic emulsifiers or crosslinking agents remaining inside the coating after curing.

TL;DR: In this paper, a short bamboo fiber reinforced epoxy composites have been developed with varying fiber length and chemical resistance tests indicate that the composite materials are resistant to acetic acid, hydrochloric acid, nitric acid, sodium hydroxide, sodium carbonate, ammonia, benzene, carbon tetrachloride and toluene.
Abstract: Short bamboo fiber reinforced epoxy composites have been developed with varying fiber length. The chemical resistance tests indicate that the composite materials are resistant to acetic acid, hydrochloric acid, nitric acid, sodium hydroxide, sodium carbonate, ammonia, benzene, carbon tetrachloride and toluene. The variation of tensile load at break with fiber length has been studied and the tensile load is found to be maximum for the fiber length of 30 mm.

TL;DR: In this article, a waterborne polyurethane dispersions with polycarbonates of 1,6-hexanediol of different molecular weight (500-3000 Da) and their properties, adhesion (Hatch adhesion) and coatings on stainless steel properties (Pencil hardness, Persoz hardness, gloss at 60°, chemical resistance, yellowness index) were characterized.
