Antas-1302 is a simple component hot melt polyisobutylene sealant with permanent plasticity. It is used as primary sealant for insulating glass and remain excellent flexibility and sealing properties over a wide range of temperatures. Antas-1302 has very low moisture vapor and gas permeability. It does not contain any solvent and does not cause cloud. Together with secondary sealants, it forms flexibility sealing system for insulating glass.
