Precautions for polysulfide building sealant
Pot life After mixing components A and B of the two-component polysulfide building sealant, the mixture gradually thickens and cannot be used beyond the pot life. The ambient temperature during use plays a large role in the curing of the sealant. The higher the temperature, the shorter the pot life. When the temperature is too low, the curing speed slows down. The appropriate construction temperature is ℃℃.
When used, the width-to-depth ratio of the sealing material should be appropriate.
When storing polysulfide building sealant, avoid direct sunlight. It should be stored in a cool, dry place at an ambient temperature of ℃ for half a year. Excessive time will affect its physical and functional properties.
