Product features and uses:
The
silane coupling agent KH-1771/KH-1770 belongs to alicyclic epoxy silane. It can be used for:
1. Modification of fiber and filling of engineering plastics such as nylon and PBT, etc. Mechanical strength.
2. The epoxy molding compound used for IC packaging can improve the adhesion and coupling of resin and filler.
3. Polysulfide sealant for construction and glass has good effect and no odor of mercaptosilane.
4. Polyurethane and latex adhesives can significantly improve the adhesion, without yellowing or affecting the storage period of the product.
Packing: 20KG/barrel.
Storage conditions and shelf life: Store indoors in a dark place, keep ventilated, cool and dry. Make sure the lid is well sealed and can effectively isolate the air. The shelf life of the original packaged products is one year, and expired products can only be used after passing the test.
