Main types, properties and application of MA-15 paint

Oil paints are now used less often than in the past. Water emulsion, acrylic, alkyd and other finishing materials came to replace them. But in some cases, replacing such products is not recommended. An example is the paint MA-15 and its individual varieties. This oil paint is widely used in construction and repair.

Description and purpose of paint

Paints and varnishes MA-15 oil paint is produced according to state standard GOST 1503-71, manufacturers are KraskaVo, Infrahim, LKZ Color and many others. This product contains combined drying oils (brand - K2, K3, K5) or drying oil of natural origin "Oxol". As additives, various fillers, pigments, desiccants are used.

The paint is available in different colors:

• beige;
• white
• yellow;
• red;
• brown;
• blue
• blue
• black and others.

The color of the product depends on the type of incoming pigment. The composition may contain titanium white, ocher, zinc white, the mummy, chromium oxide, red iron oxide and others. It is possible to produce any shade of material at the request of the client.

The use of the product is wide. They cover wooden products, apply to metal, concrete surfaces, paint the floor, walls. It is used for exterior and interior decoration, popular in construction and repair.
Material Properties:

• resistance to temperature extremes;
• rust protection;
• giving a beautiful look to products;
• formation of a durable coating in places subject to severe wear;
• light fastness, ductility;
• excellent adhesion to any surfaces;
• antibacterial qualities, ability to resist microbes and mold;
• ease of application, ease of use.

When the coating becomes completely dry, it is 100% safe and can even be used in children's rooms.

Material characteristics

Technical characteristics of this material are in the description of its properties indicated in the certificate of conformity and the batch passport.
Main parameters:

• the surface is flat, smooth, without pockmarks and craters, without defects;
• the proportion of solids in the composition - 12%, the proportion of film-forming substances - 26%;
• the degree of milling - 90 microns;
• viscosity on a VZ-246 viscometer at a temperature of +20 degrees - 64–140 (depending on color);
• hiding power of the film - 45–210 g / sq. m (depending on color);
• drying time of one layer - 24 hours at a temperature of +20 degrees;
• TML film hardness - 0.05 cu;
• light fastness of the coating - 2 hours;
• resistance to water at room temperature - 0.5 hours

Application features

Painting with MA-15 is carried out after preliminary surface preparation. It is cleaned of dirt, grease, stains, dust, the remnants of the old coating, from scale and rust. Pits and irregularities must be repaired with plaster. To strengthen the adhesion strength, it is recommended to apply a primer (alkyd, glyphthal). New wood should be pre-coated with drying oil or wood primer.

Only a dry surface can be painted. The paint is mixed before application. If the viscosity is too high, add turpentine solvent, a special thinner for oil paints.Application methods - roller, brush, direct pneumatic spray. Humidity during work - up to 80%, temperature from +5 to +35 degrees. After completion of work, tools are washed with white spirit.

Layer Consumption

Consumption of 1 m2 of the product significantly depends on the absorption of the surface, method of application, color of the material. The indicator is from 55 to 240 g / sq. m surface. Metallic substrates need less material than wooden ones.

Layer thickness

When measuring the thickness of one layer of MA-15 is 25-30 microns. The coating in two layers is 50-60 microns. It is recommended to apply two layers without a primer, or one with a preliminary primer. The thickness of the layer depends on the preparation of the painters, the method of coloring, the viscosity of the product.

Surface drying

Usually enough 24 hours of drying the coating "on stick" at a temperature of +20 degrees. But depending on weather conditions, temperature and humidity in the room, the period of complete drying can be 4-120 hours. The final properties of the material appear 5 days after application.

Coating Life

If you comply with all the requirements for surface preparation, properly paint, dry, then a coating in 2 layers will last at least a year. It is about the complete preservation of its decorative properties when used in a temperate climate. Application temperature - from –45 to +60 degrees.

Staining schemes

For metal, the surface must first be primed with primers of the grades GF, VL, PF, FL. In the presence of rust, a coat of Unicor or a rust converter is preliminarily applied. After applying 2 layers of paint MA-15. Iron products without traces of rust can be coated with paint in 2 layers without a primer, wooden, treated with varnish, in 1-2 layers.

Other MA paint series

Other paints and varnishes related to oil are on sale. Their properties and parameters are described below.

Meerk MA-15

Iron meerk is used for processing roofs, pipes, and other metal surfaces. The product has anticorrosive properties, the coating is resistant to temperature extremes –50 ... + 60 degrees. It is well polished, has high adhesion.
Main characteristics:

• color - red, red-brown;
• consumption - 0.1-0.25 kg / sq. m;
• viscosity - 80–160 s with a VZ-4 viscometer;
• hiding power of the film - 35 g / sq. m;
• solids content - 14.5%;
• milling degree - 80 microns.

MA-015

MA-015 thick-grated paint is produced according to GOST 8292-85, is a paste with a mixture of pigments and fillers. Unlike liquid grated paints, which are ready for use, thick grated paints need to be diluted with linseed oil in a volume of up to 40%. This paint is applied indoors, keeping properties throughout the year. It is applied with a brush, roller to metal and wooden surfaces.

Main characteristics:

• color - green, blue, red and many others;
• layer thickness - 15–20 microns;
• drying time - 24 hours at +20 degrees;
• the degree of milling - 50 microns;

MA-0115

These paints are referred to as oil earthenware MA-0115, in the series are produced minium, mummy, ocher. They are made on an alkyd, vinyl polymer base, and include a number of polyesters. Used for painting metal and wood indoors, with the exception of floors.

Specifications:

• consumption per layer - 55–240 g / sq. m;
• drying time - 24 hours at +20 degrees.

MA-22

Paintwork material MA-22 is a suspension of dyes, fillers on drying oil with the addition of desiccants. The paint is used outdoors and indoors to protect metals from corrosion, wood - from moisture.

Main characteristics:

• consumption - 100–180 g / sq. m;
• colors are diverse;
• solids content - 12%;
• viscosity - 65–140 s with a VZ-246 viscometer;
• film hardness - 0.05 cu on the pendulum device.

MA-25

Oil paint MA-25 is used in the air and indoors to protect wood and metal from damage. This tool is more weather resistant than the previous one. It perfectly withstands temperature changes, moisture. Drying time - 24 hours, milling degree - 80 microns, consumption per square meter - 60–240 g.

All paint series should be used, not forgetting personal protective equipment. Work is carried out only in a mask, gloves, with good ventilation of the room.
