Product details

HY563 is a one-component rubber modified polyvinyl chloride sealant, referred to as spot welding sealant. It contains no solvent,no isocyanate, anti-pollution after curing, environmental protection, excellent heat resistance and anti-aging ability. It is suitable for spot welding and sealing joints of automobile bodies, train cars, ships, etc. This product meets environmental protection requirements, does not contain harmful substances in GB18583 "Limits of Hazardous Substances in Adhesives for Interior Decoration Materials", and complies with EU ROHS and REACH environmental protection standards.

Curing mechanism
HY563 spot welding glue, curing method is heating curing. The higher the temperature, the faster the curing; the general heating temperature is 160~180℃, and the time is about 30 minutes, the customer can decide according to the actual operation process.
