VPU-1
Hydrophobic PU Grouting Materials
Introduction
VPU-1 is a common one-component hydrophilic polyurethane grouting
material. The composite poly polyol reacts with the polyisocyanate
to form a hydrophilic chemical grouting material terminated by
isocyanate. It reacts rapidly with water, solidifies and expands
the closed crack, thereby achieving Quickly stop the water. This
product is milky white elastic colloid after reaction with water.
It has the advantages of high speed, high strength, small shrinkage
and strong impermeability. It is widely used in waterproof
tunneling projects such as subway tunnels, water conservancy and
hydropower, underground garages and sewers.
Characteristics
1.Low viscosity, quick reaction in water, forming impervious
elastic colloidal concretion body by reaction with good water
sealing
performance.
2.Reacting with water, it forms ivory elastic colloidal concretion
body, which has the advantages of high compressive strength, low
temperature resistance,good elasticity and penetration proof quality.
3.Good effect on mixing with water. The product can penetrate into
crack deeply and the crack can be sealed thoroughly by
concretion body.
4.Good dilatability,big water content ,good water affinity and
groutability, meanwhile the viscosity and curing speed can be
adjusted
according to customer's requirement.
5.It can be widely used in waterproof projects such as DAMS,
subway, tunnel etc.
