Polysulfide sealant
Characteristics and applications:
The double-component polysulfide sealant is a non - solvent mixture (A, B component) RTV sealant. It has good air tightness, weather ability and UV-resistance, excellent oil resistance and solvent resistance of which do not have any influence on the desiccant and aluminum material. It can be used for the bond and seal of insulating glass and for other waterproofing, bond and seal as well.
Main technical indicators:
1. Appearance: A is gray and white uniform pasty consistency. B is black uniform pasty consistency.
2. Solid content: 100%
3. Density: A 1.65±0.05(g/cm3) B 1.50±0.05(g/cm3)
4. Mixed proportion: A:B=100:7-100:14 (Volume ratio )
5. Anti-dropping 2Mm (mixed)
6. Application period: 15~60min
7. Drying period 3h
8. Bonding strength
9. Mist: none
Packaging:
1.barrel packaging: A/B: 300kg/30kg per barrel
Construction 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℃~50℃. The bonding effect will be affected in excess of this range.
