Biocomponents polysulphide sealant is a type of room temperature curing sealant, solvent free
The polysulphide sealant 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.
1.Cures at ambient temperatures to a tough, elastic and permanently elastic rubber like material.
