Acrofast Primer Surfacer Zinc Phosphate

 
Tuff coat Polymers Introduction :
Acrofast Primer Surfacer is based on synthetic alkyd resin suitably modified with acrylic monomers &plasticizer. It contains Zinc Phosphate as anticorrosive pigment. It offers good corrosion resistance, dries faster. Any type of Top Coat can be applied over this primer coat. This primer is available in different shades like red oxide, Grey, White & Off White.
The range of Application :
Suitable for application as a priming coat on steel structure, M.S job, pipelines FRP Sheets, & Wood, P.P., ABS. This can be Top Coated with NC paints, Enamels, Polyurethane and Epoxy paints.
Tuff coat Polymers Key Properties of System :
It can be used as undercoat for many types of paints.
Faster drying than other synthetic primers so immediate over-coating
Resists most salts & alkalis & mild acids.
Resist to splash of aromatic & aliphatic solvents. (Immersion is not recommended)
Excellent Water & Oil/ Grease Resistance.
It is single component primer as a under coat for Polyurethane Paint with lower D.F.T.
Tuff coat Polymers Product Data :
Composition
Especially syn modified alkyd, plasticizer, & corrosion inhibiting pigments, suitable solvents like aromatic, ethers, & alcohol & ketones.

Tuff coat Polymers Direction for Use / Application :

Remove oil, grease & other contaminations using proper degreasing agents from Ferrous substrate. For heavy corrosive conditions blast clean the surface [for ferrous substrate] For FRP, ABS, PP clean the surface with alcohols like iso-propanol etc,

Before applying the Primer confirm that no rust particle remains on the surface. Stir the material thoroughly in the container (There may be soft settling on storage condition). Then make the paint suitable for application viscosity by using recommended thinner. Apply by conventional spray or by brush. Take care to close the container immediately after removal of paint to avoid moisture intake & loss of solvents. Do not apply in very humid condition or during the raining, fog, or mist. Also do not apply at very low temperature bellow 10 0 C
Over coating can be possible after 15-30 minutes interval.

Tuff coat Polymers Limitation :
This primer has some limitations like poor resistance to strong acids and ketonic solvents
