is a kind of room-temperature vulcanized sealant with high performance especially formulated for secondary seal for Insulating glass. The sealant has excellent elasticity and adherent stability to various glass, aluminum, PVC and metals, the sealant is stable and compatible to most sealants. The polysulphide sealant provides outstanding resistance to weathering and chemical attack from solvent, alkalis, dilute acids, oils and grease.
Features: 1.Cures at ambient temperatures to a tough, elastic and permanently elastic rubber like material 2.Durable, good chemical resistance,remains unaffected by UV rays, ozone and weathering conditions 3.Economical, easy to use 4.Non- sag in vertical and overhead joints 5.Excellent repairability property

on 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.
