Description
iSAP 311 is a non-chromated inhibited surface adhesion promoter formulated to prepare surfaces prior to painting aircraft exteriors. It is engineered to replace chromated conversion coatings and other uninhibited pretreatments and adhesion promoters. iSAP 311 has been tested for broad spectrum materials compatibility, adhesion promotion and corrosion resistance in both chromated and non-chromated paint system stackups.
