Mipa Alu-Chrom-Spray is a high quality heat resistant aluminium coating for metal substrates like exhaust systems. It provides anti-corrosive protection and is conductive, making it suitable for spot welding. The coating is heat resistant up to 800°C and highly resistant to acids and lyes. It requires pre-cleansing with a silicone remover and should be applied in 1-2 thin coats at a distance of 20-30cm, with 1-2 minutes between coats. The coating dries within 10 minutes and reaches full hardness after 24 hours.
