PBI Performance Products’ standard PBI solutions are suitable products for film casting, dip coating, spray coating and resin impregnation. PBI can be firmly adhered to steel, stainless steel, aluminum, copper, nickel-chromium, glass, ceramics and plastics. PBI coatings are highly resistant to heat and chemical attack. PBI will provide electrical insulation and wear resistance.
Free standing films and micro porous hollow fiber membranes can be produced from PBI solution for PEM cells, ultra-filtration, nano-filtration, gas separations, organic chemical pervaporation dehydration, and forward and reverse osmosis.
S26 is a solution containing nominally 26% w/w PBI solids in conjunction with 1.5% w/w LiCl salt in dimethylacetamide (DMAc) to form a 2100 Poise solution. This grade is easily thinned and can be used for membranes, films or coatings. The LiCl can be washed out in 80C water bath.
S10 is a solution containing nominally 10% w/w PBI solids in dimethylacetamide (DMAc) to form a 90 cP solution. This PBI solution is ready to use for coatings. S15 is a nominal 15% PBI solids solution with 750 cP viscosity for thicker applications or for thinning by the user.
Several variants of our base polymer coatings have been developed for tailored coating applications to provide specific performance or adhesion properties. Contact us to find out if a unique formulation is right for your purpose.
Alternately a PBI powder can be provided for a user to self-dissolve into DMAc, NMP, DMSO, Pyridine or NMF.
