Descripción del producto

SCOPE:

HAMBOND-A chemical is designed for the treatment of aluminum, its alloys or zinc metal surface by spray or immersion application. The treatment forms on the aluminum or zinc surface a thin amorphous oxide trivalent chromate coating iridescent to yellow brown in color depending on the alloy and treatment time. This coating provides good corrosion resistance and excellent paint adhesion with the base metal and it also provide efficient corrosion resistance for unpainted surface as well.

PRINCIPAL USE

It produces chromate coating on aluminum for excellent paint adhesion and corrosion resistance.

 

PROCESSING TIME

2 *3 minute immersion at ambient temperature

COVERAGE

 **3 kgs/**0sqm

REQUIRED CONCENTRATION

 3 *5% with respect to the volume

 BENEFITS
 

• Low-cost option for corrosion and wear protection
• A bonding agent for paint and adhesives
• A lubrication carrier
• Conductive surface
• Minimal electrical resistance
• No effect on critical dimensions, in most cases

• Class 1A coatings are thicker and intended to provide better corrosion prevention when left unpainted as well as to improve adhesion of paint finish systems on aluminum alloys.

• Class 3 coatings are intended for use as a corrosion preventative film for electrical and electronic applications where lower electrical resistance is needed or required.
