Phenolic resins properties
Web20. apr 1993 · The resins were prepared with various curing accelerators and raw epoxy resins having different molecular weights. We found that as the crosslinking density of a cured resin increases, glass transition temperature ( Tg) rises and the relaxation time becomes longer. WebPhenolic coating offers consistent, high-grade protection against corrosion, scratches and cracks. Baked phenolic coatings can be used in a wide range of pH environments, even in extremely acidic environments as it has excellent chemical resistance to acids even at high temperatures up to 120°F/48°C.
