HS-970 Thin-Film Polysilazane Coating

HS-970 is a polysilazane thin-film formulated coating product available in basic colors that offers extreme abrasion resistant, corrosion protection, and works at extreme operating temperatures.

This Hybridized Polysilazane covalently bonds “directly” to all ferous and non-ferous alloys, composites, rigid plastic alloys, etc. without the need of other coatings or primers.

It is applied as a thin coating (0.4 to 1.0 mil dry film thickness) that will ambient or oven cure.  This coating has passed the 3500 hr ASTM B117 salt spray test 5 present solution on Alodine 600 panels.
