MT-667 is a single component sealant based on silane modified polymer, which solidifies into an elastomer by reacting with moisture and has good adhesion to many substrates. It is used for elastic bonding of metals and plastics, such as bonding of side panels and roof covers in vehicle and caravan manufacturing.
MT-6677 is a two-component modified silane sealant that can achieve rapid curing at room temperature, with good adhesive properties, excellent electrical insulation, and high and low temperature resistance (-40 ℃~100 ℃). It can be used for bonding different substrates, filling seams, coating and protecting against gas pollution.
