Low modulus two-component polyurethane building sealant

Low modulus polyurethane sealant, polyurethane sealing paste is a two-component curing type, A, B two components, component.A is colorless or light yellow viscous polyurethane prepolymer, and group B as curing agent and additives mixed dehydration black paste or liquid the body, according to the requirements of a non sagging type and self leveling. Mainly used in bridges, basement, swimming pool, reservoir, dam, tunnel, subway and other projects.

Construction of low modulus two-component polyurethane building sealant

1) for the period: two-component sealing paste a, group B after mixing the mixture, gradually thickened, exceeds applicable period cannot be used. The use of environmental temperature when considerable effect on curing sealant, the higher the temperature for the shorter period, the low temperature curing slow application working temperature 5 to 35 DEG C is appropriate.

2) the width depth ratio of the sealing material should be appropriate.

3 low modulus two-component polyurethane building sealant to avoid direct sunlight, should be placed in a cool and dry place, away from the fire source; in particular, to pay attention to the packaging barrel seal intact, valid for one year.
