Chemat Technology has been
awarded a patent for developing a safe metal pretreatment solution for adhesive
bonding without Volatile Organic Compounds. Chemat's pioneering
efforts utilizing the sol-gel process has resulted in a novel solution for
metal pretreatment to enhance adhesive bond performance.
This stable, water based product is designed to
replace many hazardous surface pretreatment solutions such as those found in the
chemical etching or anodization processes.
Surfaces treated with this product will
have superior adhesive bonding at considerably
lower cost in comparison with other
techniques. The solution adhesive bonding and offers mechanical properties and corrosion
resistance.
Easily applied, this ready-to-use solution deposits a thin oxide layer on the metal
surface through a simple "dip" or "spray" cure method.
The product has an extended shelf life and is capable of cross
linking when applied to a metal surface.
It is a micron-thin composition that forms
an adherent coating that has a substantially
uniform distribution of metal, silicon, and
oxygen throughout the thickness of the coating.
It is capable of bonding with the material to be fastened
to a metal surface forming a strong adherent bond
between the metal surface and the material.
Chemat Technology, Inc. foresees this product as a
tremendous benefit to the aviation, aerospace, sporting goods, and
construction industries to make adhesives bond better without compromising safety of the
environment. |
