Recommended use

The epoxy primer ZINEP is used to protect metal structures from corrosion in the atmosphere, including those with high corrosion activity. The coating is resistant to sea and fresh water, aqueous solutions of salts, to oil and oil products. ZINEP can be used as a primer in complex corrosion protection systems, and as an independent anticorrosive coating.

DESCRIPTION

ZINEP is used as a primer in coating systems with materials based on epoxy, polyurethane, vinyl chloride and copolymer-vinyl chloride bases. The zinc powder contained in the composition provides cathodic protection of steel.

ZINEP primer possesses all the advantages inherent in epoxy-based materials, including excellent adhesion to metallic surfaces, high chemical resistance, and mechanical strength.

Due to its high operational characteristics, epoxy primer is widely used to protect objects operating in aggressive industrial environment.

CONSUMPTION PER M2

The theoretical consumption for a single-layer coating is 195 - 390 g/m2.

 

SURFACE PREPARATION

degrease metal surface to the first degree according to GOST 9.402;

perform abrasive blasting of the metal surface to degree 2 according to GOST 9.402 (Sa 2 1/2 or Sa 2 according to ISO 8501-1) with roughening, the recommended surface profile Rz is ranging from 30 to 50 microns (using a G-type comparator, between segments 1 and 2, but below segment 2). For hot-rolled steel, mechanized and manual surface cleaning is allowed up to degree 3 according to GOST 9.402 (St 3 or St 2 according to ISO 8501-1).

Application on a smooth surface without roughening is not allowed;

remove dust.

INSTRUCTIONS FOR USE

prior to use, mix the base of the primer to a homogeneous state;

add the primer hardener to the base, stirring (the mass ratio is 5.5:100, respectively); stand for at least 30 minutes before application.;

mix thoroughly before application until smooth;

if required, dilute to working viscosity immediately before application.

Apply in factory and field conditions in 1-2 layers using airless, pneumatic (air) spraying, roller, or brush methods at temperatures ranging from 0 to plus 40°C and with relative humidity not exceeding 85%.

 

Each subsequent layer of the ZINEP primer should be applied when the previous one dries "to tack free" (a light finger press does not leave a trace on the coating and does not give a feeling of stickiness).

 

Minimum holding time of the ZINEP coating before applying anticorrosive coating materials (at a temperature of (20 ± 2) ° C and relative humidity (65 ± 5)%) is 3 hours, before applying fire retardants - 24 hours; before packaging and shipping structures – at least 24 hours.

 

The maximum overcoating interval is not more than 1 year. The exposure time of the coating before use in aggressive environments is at least 7 days.
