Reactive Polymer Double-Component Polyurethane Waterproof Coating
311I-A/311I-B
Description
311I-A/311I-B two component polyurethane waterproof coating is a reactive polymer
waterproof coating composed of components A and B, where component
A is a polyurethane prepolymer and component B is a curing agent.
During usage, it is necessary to mix components A and B in a fix
proportion, stir evenly, apply on the substrate, and react to
solidify to form a continuous, flexible, and seamless rubber
waterproof layer.

Performance
311I-A/311I-B complies with Polyurethane Waterproof Coating (GB/T19250-2013)
Product Features
Excellent physical and mechanical properties:
311I-A/311I-B is characterized by high tensile strength, high resistance to
deformation (shrinkage and cracking) of the substrate, and good elasticity and flexibility.
Good bonding performance and high adhesion:
311I-A/311I-B can be bonded to different bases, and can be directly applied on
the substrate that meets the requirements, with the bonding strength above 1.0 MPa.
Good construction performance:
After the component A and component B are mixed in a fix
proportion, construction can be carried out; 311I-A/311I-B can be applied thick, and the thickness can be 2 mm after applying
for 2−3 times, with a dense coating film without pinholes or bubbles.
Excellent water and corrosion resistance:
The film will be formed through chemical reaction, which is
resistant to water erosion, corrosion and mold, especially applicable to waterproofing in long-term immersion
areas.
Excellent flexibility at low temperature (-35°C):
311I-A/311I-B is applicable to waterproofing works in low temperature
environments owing to its crack-free performance after bending.
Environmental friendliness:
Solvent with high boiling point is used, and no coal tar or toxic
solvents such as benzene, toluene and xylene are added.
Scope of application
Applicable to waterproofing works for underground engineering,
bathrooms, kitchens, balconies, pools, parking lots, etc.; non-exposed roof waterproofing works.
