HS-974 Polysilazane Nano-Ceramic in Colors

The HS-974 is a polysilazane thin-film formulated coating product that offers good abrasion resistant, corrosion protection, and high operating temperatures and/or direct flame. It is available in limited metallic and solid tone colors that withstand extremes.

The HS-974 is a high performance, ambient curable and/or oven cured high Temperature use product.  The HS-974 coating is designed for uses that demand a coating that offers

  • High temperature and flame fesistance
  • Good corrosion resistance
  • A long lasting, smooth, thin film coated surface

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 applies as a thin (0.4 to 0 .70 mil dry film thickness) that will ambient or oven cure.
