Study on the properties of the hybrid organic coatings for corrosion protection

Solid state Physics

Abstract

Organic coatings play an important role in preventing the metal substrate from the adverse effects of corrosion. Coatings are developed by single polymeric resins and or a combination of resins with or without pigments Silicone resin (S2) and polyester resin (P2) was used to develop binders with different weight ratios. Polyisocyanate was used as the curing agent. Physical, mechanical, thermal, and electrical properties were studied. The maximum value 5B has been attained by the S240P260 and S250P250 coatings. The binders containing 40% S2 and 70% P2 and 50% S2 and 50% P2 showed high performance compared to the samples containing 20, 30, 70 and 80% of S2 40% P2 resin with S2 resins withstood temperatures up to 448 K for 24 hours and from the potential time measurement it has been found that S240P260 could withstand without any formation of corrosion for a longer time.
