8 resin types + 9 solvents. Engineers look up products by resin.
Bisphenol A diglycidyl ether, crosslinked with amines into a 3D network. Excellent adhesion, chemical and alkali resistance. Standard resin for anti-corrosion primers and floor coatings.
Polyol + isocyanate (MDI/HDI) crosslinking. HDI aliphatic PU is non-yellowing, main resin for outdoor topcoats and soft-touch.
CTFE-vinyl ether copolymer, C-F bond energy 485 kJ/mol. QUV 3000h gloss retention ≥80%. Best ambient-cure weathering resin.
Si-O main chain bond energy 452 kJ/mol. Long-term resistance to 200-600°C. Used for exhaust pipes, chimneys, boiler exteriors. Air-dry or 200°C bake. Aluminum powder type shows metallic gloss retention. Stainless steel substrate requires dedicated primer.
Epoxy ring-opening with methacrylic acid, peroxide-cured. Resists acids, alkalis and solvents. For carbon fiber wetting and FRP linings.
Multifunctional acrylate monomers + photoinitiator, UV radical polymerization. Very low VOC, high line speed. For 3C housings. Higher functionality, higher crosslink density, better abrasion resistance but more brittle.
Isocyanate + amine-terminated polyether, second-level gel. 1:1 plural-component spray, 1-5mm film in one pass.
Add 0.3-1.5 wt% graphene oxide (GO/rGO) to epoxy / polyurethane, layer maze extends penetration path 5-10x. Also provides conductivity (percolation threshold ~0.5wt%) and thermal conductivity (5-8 W/m·K) performance.
