Potential Applications of silane coupling agent:


(1) It applies to polyethylene and copolymers with all various complex- shape and all densities or those composites 

that require the large machining tolerance and are filled in, and increase their applicable temperature, high anti-pressure pyrolysis, compressive resistance, memory, abrasive, wearresistance and impact resistance.


(2) With the function of both coupling agent and cross-linking agent, its suitable polymers such as polyethylene, 

polypropylene, unsaturated polyester, etc.  It can be used to improve the affinity of glass fiber, inorganic fillers and resin to react with vinyl, usually used in polyethylenecables and pipes of silane crosslinked polyethylene.


(3)It can be used for acrylic paint copolymer, made to special paints/coatings of the external walls. 

Itcan be use as the promoter for silicone rubber, metal and textile.


Packing & storage of silane coupling agent:


1, painted Iron drum or plastic drum or IBC

  packing of 190kgs/drum,15200kgs/1x20 `gp

  big packing of 950kgs/IBC,19000kgs/1x20 `gp

2, Sealed well, store in a cool, dry place. Avoid light.
