(1) As coupling agent with double group, it can improve the adhesion of orgenic material to inorganic ground material, is a kind of all-purpose anchoring agent applicable for most organic and inorganic materials.

(2) As the material to produce diamino-type amino modified silicon oil and many kinds of super soft finishing agent of organic silicon. After amino radical bond onto the skeleton of silicon oil, greatly improve the orientation property of organic silion (molecule) onto the fabric and stengthen the affinity to fabric, which make fabric super soft, smooth, well-drape, antistatic, resistant to washing and crinkle.

(3) It can be used as coupling agent in single or double component RTVsealant to improve adhesion to materal (concrete, copper, glass, etc.). And when sealant is solidified, system appearance is clear without air bladder.

Packing & storage:

(1) Plastic barrel, net weight 10kg, 20kg, 200kg; or other packing on request.

(2) Store in a cool, dry place and avoid light.
