1.Two-component polyurethane sealant (double-component polyurethane sealant) is mainly used in the secondary sealing of hollow glass, and one-component polyurethane sealant is mainly used in the sealing of automobile.

 2.Two-component polyurethane sealant includes A component and B component, and the two components react to cure.

 3.A component is milk white or light yellow viscous prepolymer of polyurethane. B component is black paste or liquid that is produced by curing agent and auxiliaries mixed and dehydrated. It has certain elasticity and cohesiveness after curing.

2.Features:

 1 Excellent wear-resisting performance.

 2 Good softness at low temperature and good adhesion to a variety of materials.

 3 Outstanding weather resistance, oil resistance and aging resistance.

 4 Good elasticity and recovery ability.

 5 Suitable for dynamic joints, deformation joints and expansion joints.

3.Shelf life: 

12 months in the original unopened package, stored in dry and cool environment, and the temperature is between +5\'C to +35\'C.

4.Application:

 1.It is used in sealing joints of civil construction and transportation.

 2.It is also used in the connection of building materials, such as concrete preformed units.

 3.It is used in the connection and sealing joints of advanced roads, bridges, airstrips and underground pipelines.

 4.It is used in the waterproof and sealing expansion joints and deformation joints of tunnels and buildings.
