Product introduction:
SBR powder styrene-butadiene rubber is a high-tech product completely independently developed by Xianyuan Technology and has 100% independent intellectual property rights. It first polymerizes styrene and butadiene into styrene-butadiene latex through low temperature (5 ° C) emulsion, and then according to the coil material., a polymer elastomer material produced by the production of rubber asphalt non-curing coatings and the use of properties to properly graft other monomers. After adding waterproof SBR powder rubber, due to the active functional groups of SBR powder rubber itself, a special activity can be produced in waterproof membranes and coatings, so that waterproof membranes or coatings can be used in the curing process of Portland cement. The silicate in the cement forms a compound, resulting in chemical bonding to form a strong adhesive force. While improving the bonding force between the membrane and the cement base, SBR can also greatly improve the low temperature performance of waterproof membranes or coatings.
