TWO COMPONENT POLYURETHANE SEALANT

Product ID : OYD-5
Product Tags :
Product Attributes :

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.


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

The classification of two-component polyurethane sealant:


It can be divided into two kinds according to the flowability: non-slumping and self-leveling.

It can be divided into two kinds according to the movement ability: 25 and 20.

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

Features:

Excellent wear-resisting performance.

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

Outstanding weather resistance, oil resistance and aging resistance.

Good elasticity and recovery ability.

Suitable for dynamic joints, deformation joints and expansion joints.
