bicomponent polysulphide密封胶对绝缘gl

The polysulphide sealant is a type of bicomponent sealant, room temperature curing, solvent free. Features:Special design for low temperature, no deformation.Even in -50 degree celsius, good adhesion for glass,aluminum and steel.Good aging resistance, long service life. Solvent free, don’t pollute environment.

Storage:Shelf-life: 12 months stored in cool(below 27°C), dry and ventilated places. Instructions: 1. Before use the sealant,glass and related surface must be cleaned effectively to makesure clean and dry, otherwise may affect the bonding effect.2. Componenet A and B components to be designated by the mixed ratio of non-uniformcolor,so componenet A and B should be mixed as uniform color according to the ratio.3. When sealing insulating glass, it must follow one direction to adhesive so that toprevent air into compound. After this, the interface surface should be planed by knife inone direction.4. When used in bonding other materials, please contact the company before the constructionso that to provide suitable sealant and coating.5. Before construction, the product should avoid mix with silicone sealant.onstruction manual: 1. Before construction, the glass and other sticky surface must be cleaned effectively to make sure without dirt, otherwise it may affect the bonding effect. 2. A and B components to be designated by the mixed ratio of non-uniform color (available Butterfly construction site pilot test) A and B should be mixed as uniform color according to the ratio.( butterfly is available to have a test) 3. When sealing insulating glass, it must follow one direction to adhesive so that to prevent air into compound. After this, the interface surface should be planed by knife in one direction. 4. When used in bonding other materials, please contact the company before the construction so that to provide suitable sealant and coating. 5. Before construction, the product shouldn’t mix with silicone sealant, since even little silicone sealant will affect the bonding effect. 6. Temperature range: 5°C 50°C. The bonding effect will be affected in excess of this range.
