Grout Polyurethane Foam Resin For Construction Joint
1. Introduction
This Polyurethanes grouting material is one- component, low viscosity, hydrophilic, quick-setting macromolecule chemical grouting material with high waterproof efficiency. It meeting water generates chemical reaction immediately, volume expansion, The gel is insoluble in water, with high elasticity and higher strength. This product has been applied widely in waterproof and ground reinforces projects.
2. Product Feature
- Low viscosity, quick reaction in water, forming impervious elastic colloidal concretion body by
- reaction with good water sealing performance.
- Reacting with water, it forms ivory elastic colloidal concretion body, which has the advantages of
- high compressive strength, low temperature resistance,good elasticity and penetrationproof quality.
- Good effect on mixing with water. The product can penetrate into crack deeply and the crack can be
- sealed thoroughly by concretion body.
- Good dilatability,big water content ,good water affinity and groutability, meanwhile the viscosity and
- curing speed can be adjusted according to customer's requirement.
3. Advantages
- Hydrophilic and hdrophobic kinds
- Function:stop water, void filling, reinforce
- Used in coal mine, dam, tank and more
- VOC or solid content is 70%~100%
- Activated fast with water
- The solidify product can swellable with water
- Non-toxic LD50 be more than or equal to 9000mg/kg
