Thurmalox 280C Aluminum is a VOC compliant, air drying, heat resistant coating based on silicone resins formulated specifically to protect metal surfaces operating at temperatures from 500°F (260°C) to 1200°F (648°C). For maximum corrosion protection, metal surfaces should be primed with Thurmalox 245C silicone zinc dust heat and corrosion resistant primer and topcoated with Thurmalox 280C Aluminum. The 245C primer/280C topcoat system provides outstanding adhesion, film integrity, corrosion-, weathering- and thermal shock-resistance throughout this entire temperature range.
