Vtech VT620s MS Polymer Sealant Hybrid Silicone Sealant Polyurethane - Putih

Vtech VT620S Hybrid Sealant VT-620 LM MS Sealant is a general-purpose sealant based on advanced MS Polymer technology. It is a single-component elastomeric sealant with excellent adhesion property on various substrates like concrete. After curing, the sealant is permanently elastic and has a movement capability of ±50%. It is able to comply with the stringent requirements of ASTM C920 as well as the SCAQMD rule 1168 (Architectural Sealant) for low VOC. Unlike polyurethane sealants, VT-620 is solvent-free and isocyanate-free; ensuring that the cured sealant will not shrink or have bubbling issues. It is also free of silicone oil, minimising building aesthetic issues caused by oil staining and dirt streaking problems often associated with silicone sealants Recommended for sealing concrete joints like precast wall panel joints, expansion joints, control joints, connection joints, etc. It is also ideal for window frame perimeter sealing especially when the sealant needs to be painted. Other recommended applications include sealing of GRC panel systems, anodized aluminium, masonry, porcelain, coated metal, finished wood, epoxy and polyester panels, UPVC, polystyrene, and stainless steel
