1) Application period: after two-component polysulfide building sealing paste group A and B are mixed, the mixture gradually thickens, and it can not be used after the application period. The ambient temperature when used plays a considerable role in the curing of sealing paste. The higher the temperature, the shorter the applicable period, the slower the curing speed when the temperature is too low, and the appropriate construction temperature is 5℃ ~ 35℃.
2) When used, the ratio of width and depth of sealing material should be appropriate.
3) polysulfide building sealing paste storage should avoid direct sun exposure, should be placed in a cool and dry place; It can be stored for half a year at the ambient temperature of 5 ~ 26℃. Too long time will affect its physical and service performance. Such as: SS521 is single component, neutral curing, designed for glass, aluminum curtain wall and glass daylighting roof and metal structural engineering structural adhesive seal designed silicone sealant structure, excellent bonding performance of structure and the weathering resistance, after artificial accelerated weathering test, various physical and chemical properties have no obvious change in the sealant. Use a glue gun to squeeze the glue from the sealant cylinder to the part that needs to be bonded and sealed. The sealant absorbs moisture in the air at room temperature and solidify into an elastomer to form an effective seal. General product characteristics: single component, neutral curing, non corrosive to metal, coated glass; Excellent weather resistance, aging resistance, uv resistance, ozone resistance, water resistance; Excellent high and low temperature resistance, little change in the range of -30℃ ~ 90℃; Excellent adhesion to most building materials; It has good compatibility with other neutral silicone rubber. Main uses: glass, aluminum curtain wall and glass lighting roof and metal structure engineering structure bonding seal; Insulating glass two way bonding seal.
