Poly sulfur waterproof building sealant note

1) for the period: two-component polysulfide sealant for building a, group B after mixing the mixture, gradually thickened, exceeds applicable period cannot be used. The use of environmental temperature when considerable effect on curing sealant, the higher the temperature for the shorter period, the low temperature curing speed slowly, the construction temperature 5 to 35 DEG C is appropriate.

2) with the use of poly sulfur waterproof building sealant, sealing materials, the ratio of the width to be appropriate.

3) poly sulfur waterproof building sealant storage to avoid the sun, should be placed in a cool dry place; in 5 to 26 degrees Celsius environment temperature can be stored for half a year, the time is too long will affect its physical and use performance。

Composition and properties of polymer waterproof sealant:

Polysulfide sealant waterproof system of liquid polysulfide rubber as the main material, with tackifying resin, curing agent, accelerator, reinforcing agent made of strong sealant. This sealant has excellent resistance to oil, hydraulic oil, water and atmospheric aging resistance of various chemical properties and the heat and is generally can be vulcanized. According to the group can be divided into two components (or three components) and one component type. The machining process with premixed - grinding - filling.
