DEFENS AL.UR-01 (1K) Alkyd – urethane soil

Single-component alkyd-urethane primer containing anti-corrosion additives that enhance the protective properties of the formed coating.

Application: ,

Specifications

Designed for painting metal and concrete with a long service life of up to 10 years.

Can be applied using air and airless spraying methods, as well as with a roller and brush. Due to the low toxicity of the solvents contained in it, the primer is convenient to apply. It can be used as a primer in anti-corrosion protection systems for steel surfaces exposed to mechanical and chemical influences, as well as atmospheric effects in humid climates and industrial environments.

Recommended for painting rolling stock, automotive transport, bridges, steel and reinforced concrete structures, tanks, equipment in the chemical and petrochemical industries, port and waterfront facilities, marine and river vessels, power line towers, etc.

Coloring in any color at the request of the customer according to the RAL scale is possible.

Optimal budget coating

Requirements for the substrate

The metal surface must be dry, cleaned of rust, debris, dust, grease, and other contaminants that may act as separators. If necessary, treat the substrate by sandblasting or shot blasting to a degree of Sa 2-2.5 (ISO 8501-1:2007). After cleaning, the steel or galvanized surface must be dusted and degreased.

Previously painted surfaces suitable for repainting. Remove contaminants (e.g., grease and salts) that hinder. Surfaces must be dry and clean. Old surfaces with paint that has exceeded the maximum time for applying the next layer must be sanded to roughness. Damaged areas of the surface must be treated according to the substrate preparation and maintenance instructions. The location and timing of the preliminary surface preparation for painting should be chosen so that the treated surface remains dry and clean until the next stage of painting the product begins.

Application

Before applying the primer-enamel, mix thoroughly for at least 5 minutes until a homogeneous consistency appears. Apply to the prepared substrate using air or airless spraying, brush, or roller. To achieve the required working viscosity of the material, the addition of a mixing solvent (solvent) is possible.

The surface to be painted must be dry and have a temperature at least 3 °C above the dew point. The recommended number of layers is 1-2. Work should be carried out in accordance with the ISO 12944-7:2017 standard.

Packaging and storage

The paint is stored in a tightly closed container, protecting it from moisture and direct sunlight, away from heat sources, at a temperature between -20 and +30°C. The warranty storage period is 12 months from the date of manufacture without violating storage conditions. Minor delamination is allowed during prolonged storage, which does not affect the quality of the material.

Cleaning of tools

Working tools and equipment are rinsed with solvent R-4 immediately after use.

Safety measures

This product is intended for professional use only in industrial facilities according to the recommendations provided here, as well as safety instructions provided to customers along with the containers containing the paint. All work, including the application and use of the product, must comply with health, safety, and environmental protection requirements, all regional standards, and instructions.

When carrying out painting work, use personal protective equipment, avoid contact with eyes, respiratory tract, and skin. Keep away from fire.
