Pre-treatment

The service of in house pre-treatment is available.

On aluminium castings and product machined from solid in aluminium we can add Alacrome 407-47. This gives you an excellent conversion coat to the material for corrosion resistance and adhesion prior to painting or powder coating.

On Zinc castings we can pre-treat with Grenodiene for good adhesion prior to painting or powder coating.
