KRAFTHAUS KH50 - Zinc Spray (Bright)
- KRAFTHAUS KH50 Bright Zinc Spray delivers sacrificial corrosion protection using 99.995% high-purity zinc in an alkyd resin base. It creates a bright, hot-dip galvanized metallic finish perfect for touch-ups, weld protection, and repairing steel and iron
- Code:KH-50
KRAFTHAUS KH50 Zinc Spray (Bright) provides exceptional, long-lasting sacrificial protection for ferrous substrates without the need for a dip-tank process. Formulated with a 99.995% high-purity zinc metal charge suspended in an alkyd resin base, the spray applies overlapping layers of microfine zinc particles that self-sacrificially defend base metals—even if the top coating is scratched or chipped.
The cured film matches the appearance of fresh hot-dip galvanizing, making it the ideal solution for seamless repair work, touch-ups, and structural metal maintenance. Engineered for durability in demanding environments, KH50 passes 500 hours in salt spray testing (ASTM A780) and exhibits superior resistance to humidity, marine atmospheres, industrial weathering, and high temperature service.
