Aquacoat KS-979-Polyurethane Waterproofing Coating for adhesion
PRODUCT DESCRIPTION
KS-979 is a polyurethane waterproof coating researched by keshun company for adhesion of waterproofing membrane.
WHERE TO USE
Waterproof for railway and concrete bridges, used to bond waterproof membranes
Application: Africa Ethiopia reconstruction Aid project
PRODUCT STRUCTURE
PRODUCT FEATURES
- Excellent stretchability and elongation，strong bonding with substrate and large elasticity can bearing deformation of concrete
- No solvent added during construction， safe and environmental friendly，fast cured，fully meet construction progress requirements
- Excellent low temperature resistance and water impermeability，good wear，acid，and alkali resistance
SPECIFICATION
INSTALLATION
1. Substrate Preparation
Substrate should be cleaned and then the honeycomb, pockmarks and cracks should be repaired with polymer mortar.
2. Ingredients
Mix component A and B as required, and stir with electric mixer about 1-2 minutes.
3. waterproofing layer
Construct the second coating after the first is dry.
Brush direction should be vertical to each other. The thickness should be at least 1.5mm,usage amount of each m2 should be at least 1.8 kg.
