VT-625 Modified silicone sealant

VT-625 Modified silicone sealant (VT-625 ULTIMATE CONSTRUCTION SEALANT) general-purpose sealant formulated based on advanced MS Polymer technology. It has excellent UV and weathering properties and it features matt finish. The static charge of this sealant is low, hence attracts less dust particles and reduces dirt streaking issues on facade cladding. This elastomeric sealant is permanently elastic upon curing and has a movement capability of ±50 %. Specially formulated to achieve superior performance and feature low VOC emission and content, VT-625 is able to comply with the stringent requirements of ASTM C920 as well as contribute to the Leadership in Energy and Environmental Design (LEED) v4.1 credit. Unlike polyurethane sealants,
