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).
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.
Disadvantages:
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.
Package:
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.
