The complex facade adopts massive ACP and aluminum profiles. Acid-cure sealant would corrode metal paint and trigger coating peeling. Client required weatherresistant sealant for long-term waterproof panel joints, minimum 10-year service life without ageing & cracking.

JR-995 was applied for all ACP seams and aluminum keel joints. Neutral formula prevents coating corrosion. High-weather-resistant silicone accommodates metal thermal expansion and contraction and blocks rainwater penetration.Sealant fits tightly with panels. Inspection shows zero corrosion, debonding or cracking. Facade keeps neat and waterproof, satisfying durability requirements for commercial building.
