Notes of construction of polyurethane sealing paste
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) high modulus two component polyurethane building sealant to avoid direct sunlight, should be placed in a cool dry place, away from the fire source; in particular, should pay attention to the packing barrel seal intact, valid for one year.
