◆ XY-5SBR Powder Introduction
XY-5 is a kind of SBR powder product which is produced by the asphalt waterproof material modification. After adding waterproof SBR powder, SBR powder rubber has active functional groups, which can produce a special kind of activity. So that the material will form chemical compound with silicate in cement, chemical bonds and strong adhesive force in the process of silicate cement. At the same time, SBR can improve the low temperature performance and tensile properties of the membrane.
Using method:
Slowly added XY-5SBR powder into 150-160℃ hot bitumen mixes 30-60min, or uses high speed shearing machine and colloid mill, it has better swelling effect after shear or grind.
Package:
Packed in 20kg carton, inside package is high strength vinyl film. Keep dry, away from damp and heat.
