VICOTE® F817 Enhanced Adhesion Grade

VICOTE® is the brand name for the Victrex range of coatings

based on VICTREX® PEEK polymer. The VICOTE dispersions

are available through Victrex plc or its preferred coater

network. Contact Victrex plc for further details.

VICOTE dispersions are aqueous based, however there

may be small amounts of solvent present. Refer to the

appropriate MSDS sheet for details.

VICOTE F817 can be applied to most ferrous and non

ferrous metals. Cast metals need to be de-gassed in an

oven to prevent pin holes in the coating surface. Aluminium

and other thermally sensitive substrates may be coated

however the mechanical properties of the substrate may be

affected when exposed to VICOTE processing temperatures.

The VICOTE F817 enhanced adhesion grade can be used

on metal substrates where limited surface roughening is

allowed or desired. When using this VICOTE grade the

adhesion to a non-roughened or grit blasted surface is

much higher than using the standard VICOTE dispersions.

VICOTE F817 will withstand 24 hours boiling water test on

non-grit blasted stainless steel without loss of adhesion.

Note: Although roughening the metal surface may not be

required, removal of oils and greases must be undertaken

to obtain the optimum adhesion. Rust and mill scale

would need to be removed by conventional grit blasting

while either thermal degreasing or a conventional vapour

degreasing step should be employed to remove oils and

greases. Once this is done the substrate should not be

handled with bare hands.

Note: Phosphate pretreated substrates are not

recommended for VICOTE grades as the high processing

temperatures required for processing can result in

de-lamination of the coating.
