SEP4000 High elongation Sealant
SEP4000 is a one component sealant based on silane end-capped polyether, without solvent, free isocyanate, small organic silicon molecule and polymer.
It is environmental friendly, low VOC, and would not dirt the substrate, which is curing by absorbing the moisture from air in the room temperature.
It's widely applied to infrastructure construction fileds,which has excellent adhesion to different base,such as glass, metal,PVC,ABS,PC,PET,PBT etc.
Characteristics
Single component, easy to handle
Environmental friendly: no solvent, low VOC, without dirt the substrate.
Excellent adhesion
Excellent weather resistance
Medium intensity, high elongation
Packaging
310ml/Tube，200kg/Drum，others could be customized.
Transportation
Transport as non-dangerous goods.
Applications
Vehicle parts sealing and bonding,such as car,coach,motor
homes,train,vessel etc.
Gap sealing awaterproof for public facilities such as road, tunnel, square,
etc.
waterproof sealing: mechanical equipment and electronic instruments also parts.
