Performance and application

KH-590 is a reactive and crosslinkable silane coupling agent, which can be hydrolyzed under acidic or reducing conditions, and is widely used in natural and synthetic rubber, such as styrene butadiene, neoprene, cyanogen butadiene, ethylene propylene diene monomer, etc.

This product is applicable to sulfur horizontal vulcanized rubber, and can be used as a reinforcing agent to significantly improve the mechanical properties of the rubber compound. Especially wear resistance; It is widely used in rubber roller, tire, wire and cable, shoe sole, etc.

In addition, it can be used as a reinforcing agent and crosslinking accelerator for composite materials (such as resin glass fiber composite), coatings, inks, glues and sealing materials.


The product can also be used as resin modification additive and enzyme immobilizer.


KH-590 must be sealed for storage, otherwise it will be hydrolyzed by moisture to form polymer. KH-590 is light for skin and eyes

It is slightly irritating, so protective devices should be used.
