Thurmalox 230 series coatings are heat resistant coatings based on silicone resins and thermally stable pigments. They are formulated specifically to protect metal surfaces operating at temperatures from 500°F (260°C) to 1000°F (538°C), with peaks to 1200°F (648°C).

For maximum corrosion protection, prime metal surfaces with Thurmalox 245 silicone zinc dust heat and corrosion resistant primer and topcoat with Thurmalox 230 series. The 245 primer/230 series topcoat system provides outstanding adhesion, film integrity, color stability, corrosion-, weathering-, and thermal shockresistance from ambient to 1000°F (538°C). Thurmalox 230 series coatings are available in a wide range of standard (see Master Color Card) and custom colors.

Attached is the standard SSPC-16 for preparing galvanized and non-ferrous metals. Brush blast with garnet or aluminum oxide to create a 0.5-1.0 mil sharp angular profile. No bead or shot blasting is suitable.

Apply two coats Thurmalox 230/230C to a dry film thickness of 1.5-2.0 mils per coat. Do not apply the 245 primer to aluminum as it contains metallic zinc dust.
