Farbacoat Vinylester

Two-component thick-layer coatings with a high solids content, designed primarily for immersion conditions, if high protection against chemical attack is required. Composition based on epoxy vinyl vinyl ester resins and a number of special organic and inorganic fillers and additives.

Depending on the type and number of special fillers and additives of the “Farbacoat VINYLESTER” series coatings, the following modifications are made:

“Farbacoat VINYLESTER 51” — primer, for priming and impregnating glass materials, applied by brush, roller, airless spraying;
“Farbacoat VINYLESTER 52” — for lining pipes by the centrifugal method;
“Farbacoat VINYLESTER 53” — lining, for application by brush or roller;
“Farbacoat VINYLESTER 54” — lining, increased thixotropy, for applying with a spatula;
“Farbacoat VINYLESTER 55” — repair, for filling of shells, cracks, cavities and alignment (smoothing) of welds, drawing with a spatula

ADVANTAGES

very high adhesion to steel and concrete surfaces
high chemical resistance in the environment of concentrated solutions of acids, alkalis, salts
high temperature resistance in aggressive environment — up to 130 ° С
high mechanical resistance, abrasion resistance

RECOMMENDATIONS FOR USE

used to protect internal surfaces of pipelines, metal tanks, tanks, process equipment, concrete tanks, general-purpose metal structures where high protection against chemical attack is required, as well as at high abrasive and impact loads of the environment

APPLICATION METHOD

Coatings series «Farbacoat VINYLESTER» are supplied in two containers. It is necessary to mix such an amount that will be guaranteed spent for 0.5 … 1.0 h (depending on the modification of the coating) in appropriate proportions.

Preparation of the coating — add component II to the mechanically mixed component I and mix thoroughly.

Mix in a weight ratio:

component I — 100 m.h.
component II — 2 pm

Stir the mixture until uniform.

Long mixing should be avoided to prevent air from entering the mixture.

No need to dilute the product.

The suitability of the mixture is 0.5 … 1.0 h at a temperature of 20 ° C. Higher temperatures shorten the life of the mixture, lower temperatures prolong it.

After mixing the components, the product must be used within the indicated pot life.

Application method — after mixing the components

airless spraying: Ø0.38-0.53 mm; 15 — 20 MPa
brush
roller
putty knife
centrifugation

MODE OF APPLICATION

Surface: the better the surface is cleaned, the more resistant the coating will be.

The highest chemical and mechanical resistance is obtained by coatings applied directly to steel surfaces that have undergone abrasive blasting at least to the degree of cleaning Sa 2½

The surface of the steel is dry, free from contamination, degreased — cleaned to at least Sa 2 1/2 degree for submerged surfaces or at least to St 2 degree for external surfaces.
The surface prepared for coating should be dry, free from salt, grease, dust and other contaminants.
Before applying to concrete surfaces, make sure that the surface is clean, free from grease, oil, liquid bitumen and detergents. If the concrete is new (min. C20 / 25), then the milk of lime must be removed. Smooth concrete mechanically bring to a roughness, for example by easy bead-blasting treatment to obtain a profyle CSP-3 (according to ICRI). In case of renovation, the concrete surface should have a minimum profyle of CSP1, as well as adhesion at the level of> 1.0 MPa in the tear test.
In the case of coating operation in aggressive conditions, it is recommended to prepare the surface as best as possible and apply subsequent layers until the previous layer is completely cured.

Full cure time of the coating	20^oC	15^oC
Days	2	3

Use with caution.

Packages contain appropriate safety signs that must be observed.

Conditions of application and curing of the coating:

minimum surface temperature: 12 oC
surface temperature above the dew point (avoid condensation)
relative air humidity not higher than 85%,
good ventilation

Packaging:

Component I — metal bucket rev. 20l, net weight — 24.5 kg
component II — polypropylene capacity about. 0,55l, net weight — 0,5 kg

SHELF LIFE: when stored in a closed factory packaging at a temperature of 5-35 ° C — 6 months from the date of manufacture for component I (base) and 6 months for component II (hardener).

NOTE! The product is intended for professional industrial use. Information about the safety of the use of the product is contained in the Safety Data Sheet of Coatings of the Farbacout VINYLESTER series
