PolyurethaneSealant with Good Wear-resisting Ability

Polyurethanerubber and the prepolymer of polyurethane are the main components ofpolyurethane sealant. Polyurethane sealant can be divided into three kinds:heating curing polyurethane sealant, room temperature vulcanized polyurethanesealant and hot melt polyurethane sealant.

Andthe room temperature vulcanized polyurethane sealant is divided into two kinds:one-component polyurethane and two-component polyurethane sealant. Two-componentpolyurethane sealant(double-component polyurethane sealant) is mainly used inthe secondary sealing of hollow glass, and one-component polyurethane sealant ismainly used in the sealing of automobile.

Two-componentpolyurethane sealant includes A component and B component, and the twocomponents react to cure. A component is milk white or light yellow viscousprepolymer of polyurethane. B component is black paste or liquid that isproduced by curing agent and auxiliaries mixed and dehydrated. It has certainelasticity and cohesiveness after curing.


Primermakes the adhesion effect better.

Acomponent is milk white even paste, and it has clear color difference from Bcomponent, making the mixing easier.

Acomponent and B component in one carton, it is easier to transport and use.

Classificationof polyurethane sealant

1.Itcan be divided into two kinds according to the flowability: non-slumping andself-leveling.

2.Itcan be divided into two kinds according to the movement ability: 25 and 20.

3.Itcan be divided into two kinds according to the tensile modulus: high modulus(HM) and low modulus (LM).

Featuresof polyurethane sealant

1.Excellentwear-resisting performance.

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

3.Outstandingweather resistance, oil resistance and aging resistance.

4.Goodelasticity and recovery ability.

5.Suitablefor dynamic joints, deformation joints and expansion joints.

Shelflife of polyurethane sealant

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

Color:Acomponent is milk white or light yellow, B component is black.

Applicationof polyurethane sealant

1.Itis used in sealing joints of civil construction and transportation.

2.Itis also used in the connection of building materials, such as concretepreformed units.

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

4.What'smore, it is used in the waterproof and sealing expansion joints and deformationjoints of tunnels and buildings.


Two-componentpolyurethane sealant used in tunnel, makes the tunnel has longer servicelife.


Two-componentpolyurethane sealant makes the joint firm and solid.


Two-componentpolyurethane sealant makes the joint sealed and stout.


Two-componentpolyurethane sealant using on the road, makes the road safer and solid.
