Polybenzimidazole can also be used as a thermal resistant coating. By dissolving the PBI polymer into highly polar aprotic solvents like n,n-dimethylacetamide (DMAc), dimethylsulfoxide (DMSO), or n-methylpyrrolidone (NMP), PBI can be cast, sprayed, dipped or spin-coated onto metal, glass and other substrates – then cured to yield thermally resistant coatings. Such coatings can serve to protect substrates from corrosion, function as a dielectric layer, serve as a thermal insulator or as a high temperature adhesive.
Used in conjunction with PEEK or PAI, Celazole PBI coating makes a great tie layer to bridge CLTE mismatch. CLTE of 23 µm/mC matches that of aluminum.
PBI coatings provide an anti-fouling and low friction surface for fans in high temperature gas streams.
Used on the interior of a valve body, PBI coatings provide corrosion resistance with 9000 psi adhesive strength.
Coating the interior of oven parts reduces corrosion caused by off-gases.
Shielding of metal end-effectors and chamber parts for reducing metal exposure or imparting anti-stat property.
Used with PEEK or PPS, Celazole PBI forms a tight bond to metal substrates and helps alleviate cracks due to shrinkage of crystalline top layers.
