Characteristic and Usage:

KH-590 is a new type of coupling agent with reactivity and crosslinkable. It can be hydrolyzed in the presence of acidic and/or alkali medium. So it is widely used in nature or synthesized rubber ,resin-fiberglass composites as reinforcing agent and used as adhesiving promoter in composite material , coating , ink , adhesive and sealant etc. It is also used as additive of resin modification ,enzyme immobilization and treatment of mesoporous silica yield highly efficient heavy metal scavenger.

Physical properties:

Appearance(APHA) ≤30

GC Purity(%)    ≥98.0

Packaging and Storage:

KH-590 should be hermetically storaged ,because of its reactivity,it will be hydrolysised by moisture to form polymer.

KH-590 is supplied in net weight 200kgs in new iron drum.

KH-590 can little stimulate skin and eyes,so it is necessary to dress appliances for labor protection when contacting it.
