1. Product Introduction
MS basic waterproof adhesive is a highly elastic polymer material. It is used for the base waterproof layer, does not require a primer, and is a single-component moisture-curing product. After curing, it forms a strong and tough waterproof layer with good elasticity, high strength, and resistance to high and low temperatures. It features solvent-free, low volatility and environmental friendliness.
2. Product Features:
· Solvent-free: Free of harmful substances such as formaldehyde, toluene, and isocyanate;
· Strong adhesion: It has excellent bonding performance to concrete, cement, stone, metal, glass, ceramics, wood, etc.
· Water resistance: No delamination after long-term soaking in water;
High elasticity, effectively preventing water leakage caused by building settlement and cracking.
3. Usage
It is used for basic waterproofing layers in bathrooms, balconies, kitchens, swimming pools, sewage ponds, roofs, etc.
