Heat Curing Welding Seam Sealer S857
S857 is a heat curing, solvent-free sealant based on a polyacrylic plastisol. It can be applied to clean, bare steel or electrocoat and accepts powder paint either cured or wet-on-wet. It's used in high heat applications (200°C) where resistance to heat degradation and color change is critical.
Special Characteristics
- Used for bonding clean steel or electrophoresis plate.
- Compatible with powder paint spraying after wet adhesive or curing.
- Ideal for sealing, waterproof, dustproof, and anti-corrosion of inner/outer car body welds.
Application Examples
- Windshield and side glass for buses, cars, railway vehicles, and ships.
- Glass steel and plastic accessories (car roofs, side bodies, and fronts).
- Bonding different materials (metal, plastic, glass) requiring high tensile strength and elasticity.
