Product Description

Polyurethane rubber and the prepolymer of polyurethane are the main components of polyurethane sealant. Polyurethane sealant can be divided into three kinds: heating curing polyurethane sealant, room temperature vulcanized polyurethane sealant and hot melt polyurethane sealant. And the room temperature vulcanized polyurethane sealant is divided into two kinds: one-component polyurethane and two-component polyurethane sealant. 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).
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.
It cannot be resistant to heat for a long time, and may produce bubbles or cracks in high temperature environment.
Need to do base coating on most occasions.
Poor resistance to water, especially alkaline water.
A component: 200L/iron drum, B component: 20L/iron drum.
A component: 20L/plastic drum, B component: 2L/plastic drum.
Packed as customers' requirements.
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.
Color: A component is milk white or light yellow, B component is black.
