Building Waterproofing Polysulfide Sealant Precautions   YFKJ-5258

1) Applicable Period: Two-Component Polysulfide Building Sealant When components A and B are mixed, the mixture gradually thickens. Once the applicable period is exceeded, it cannot    be used. The ambient temperature during use significantly affects the curing of the sealant; the higher the temperature, the shorter the applicable period. At very low temperatures, the curing speed slows down. The recommended construction temperature is 5℃~ 35℃.

2) When using polysulfide waterproof building sealant, the width-to-depth ratio of the sealant material should be appropriate.

3)Building Waterproofing Polysulfide Sealant Should be stored away from direct sunlight, preferably in a cool and dry place; it can be stored for six months at an ambient temperature of 5–26℃. Prolonged storage will affect its physical and performance characteristics.
