product features

1.kh-590 is one kind has the reactive and crosslink silane coupling agent, in conditions that can be acidic or alkaline hydrolysis, extensive application of natural and synthetic rubber filler processing, such as: butyl benzene, synthetic, butyl cyanogen, triple powder etc.

2 this product applies to sulfur vulcanization rubber, as intensifier to significantly improve adhesive materials, mechanical properties, especially the wearability; widely used in plastic roller, tires, electric wire and cable, soles.

3. another as intensifier and crosslinking promoting agents can be used for composite materials (such as resin fiberglass composite material), coating, ink, glue and seal materials etc.

4. this product is used for resin modifying additives and enzyme fixative. for silicon dioxide, carbon black and other inorganic packing processing, has the very good effect.

5. because mercaptoacetic functional group, as with metal surface with special effect, rust in its treatment of gold, silver, copper and other metal surface, can strengthen its surface corrosion resistance, oxidation resistance and increase its and resins polymer adhesive sex.

6. in rubber industry, often used for processing, carbon black and silica glass fiber, mica and other inorganic packing, can effectively enhance the rubber mechanical properties and wear resistance.

7. can be used in textile fabric on shrink finishing.

packing specifications

this article adopts the 5kg packed in plastic drum, four barrels a box, a total of 20 kilograms. other specifications need reservation.

store and transportation

sealed storage, stored in a cool and dry ventilated place; avoid with acid, alkali, water etc contact; avoid rain and sun; in moisture and hot effect under meeting occurrence polymerization; is valid for one year.
