HS-965 Chromate-Free Primer

HS-965 is a ready to apply polysilazane formulated coating product that has extremely high resistance to corrosion and chemical attack while being able to endure operating conditions of 1800 degrees F as well as direct flame.  It covalently bonds to all ferous, non-ferous alloys (i.e., Titanium), composites, semi-rigid and flexible plastic alloys as well as many other substrate types.  HS-965 applies as a thin film that can be ambient or oven cured.

This coating is designed for uses where corrosion protection is of the utmost importance, regardless of environment conditions — from extreme heat or cold or chemical attack.  This chromate-free primer was designed for simple application and high-performance use.

HS-965 is a chromate-free primer polysilazane coating and has no heavy metals.

Heavy metal primers and coatings have been illegal to use for many years in the general manufacturing marketplace.  Currently only the military and aircraft markets places are allowed to use heavy metal primers to prevent corrosion and increase useful life span of components or the end product.

This restriction is in place only because there has not been a product that will protect these substrates from extreme corrosion due to environment conditions that they are expected endure.

HS-965 is an answer for preventing corrosion, while protecting the environment, “a green corrosion primer”.  It applies at 0.5 to 1 mil in thickness.

This primer serves as a corrosion resistant primer, but may also serve as the Finished Top Coat without additional coating applications.  HS-965 is available in solid tone colors.  This coating has passed the 3500 hr ASTM B117 salt spray test 5 present solution on Alodine 600 panels.

The benefits are:

• UV and Chemical Resistant
• Corrosion resistant to galvanic, salt laden water & air, chemicals
• Abrasion Resistant
• Hydrophobic
• Flame and High Temperature Resistant
