Technical Data

 

Product Description

 

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 notrecommended for VICOTE grades as the high processing temperatures required for processing can result in de-lamination of the coating.
