Since the nitrile group is introduced into the HTBN molecular chain, the nitrile hydroxy liquid rubber has good oil resistance and adhesion, aging resistance and low temperature resistance in addition to the general characteristics of the hydroxyl group polybutadiene. The product is a light yellow transparent viscous liquid with no visible mechanical impurities.
The nitrile hydroxy liquid glue mainly uses a terminal hydroxyl group property to react with a bifunctional group to carry out chain extension, and further crosslinks to form a flexible long-chain polymer to form a product. With the development of science and technology, the application field is expanding: 1. It can be used for the coating of the solid rocket motor or the thermal insulation layer, and has good mechanical properties; 2. It can be used to bond rubber and polyester with HTBN. metal. It is characterized in that it does not use solvent to cure at room temperature; 3. It can be made into a corrosion-resistant coating for use in an acidic environment; 4. The toughening agent for epoxy resin has great potential for modification of epoxy resin, and can improve its resistance to aging. performance.
Use:Used for sports shoes, work shoes, boots, safety car sealing washer, profile products, hose, movies and other (not recommended for white products).
4,Packing: in plastic woven bag lined with two layers, the net weight of each bag is 25 kg.
5,Storage: store in a cool, dry and ventilated warehouse. Guarantee period of 12 months, after which the review qualified can still use.
6,Transportation: the transport process should avoid rain, damp.
