A single-component chemically resistant fast-drying chlorinated rubber primer. It provides high protective properties of the formed coating and a long service life in chlorinated rubber coating systems for use in chemical aggressive environments.
It is used for prepriming metal and concrete surfaces with anti-corrosion protection of structures and equipment exposed to moderate chemical actions
It is used to protect pipeline volume capacity, vessels, industrial equipment, railway rolling stock, mining equipment, surface and underwear broadsides of floating crafts and so on.
The primer is intended for effective and long-term anti-corrosion protection of metal surfaces operating in atmospheric conditions (including industrial and marine atmospheres)
It is used as a high quality fast-drying primer at low temperatures. It can be also used as a primer layer in anti-corrosion protection systems in accordance with the ISO 12944-5:2018 standard.
It can be applied by air or air-free methods of dispersing, as well as with a roller or brush.

Requirements to the base
The metal surface should be dry, free of rust, debris, dust, oils, fats and other contaminants that may act as separators. Galvanized surface must be removed from dust and degreased.
Cement-containing and stone surfaces should be clean, dry (humidity is not more than 5%), without traces of bleed water, dirt, oil, as well as withstand design loads (compression capacity is not less than 200 kp/cm2), contain no fragile and stuck-on particles. If necessary, handle the base with a sand- and bead-blasting method, milling or polishing. After processing, the surface should be removed from dust and saturated with the DEFENS materials.
Previously painted surfaces suitable for repainting. Remove impurities (e.g., grease and salts). Surfaces must be dry and clean. Old surfaces with a painting that has exceeded the maximum application time of the next coat should be ground to roughness. Damaged surface areas should be handled in accordance with accepted procedures on how to prepare the base and maintenance operations. Place and time of prefinishing of the surface for applying the paint should be chosen so that the neat surface remains dry and clean until the next stage of painting the product.
Application
Before applying, the primer should be thoroughly mixed for at least 5 minutes until an even consistency is obtained. Apply it on the prepared base by air or air-free methods of dispersing, as well as with a roller or brush. To obtain the material of necessary application viscosity, it is possible to add the mixed solvent Defens. When working with the primer at low temperatures, it is recommended to use highly volatile solvents (Р-646, Р-647). The surface to be painted should be dry and have a temperature of a 3 °С above the dew point. Recommended number of layers is 1-2. Perform the work control in accordance with the ISO 12944-7:2017 standard. Avoid different staining techniques whenever possible.
Package and storing
The material is stored in a tightly closed packaging at a temperature from -20 up to +30°С, away from moisture and direct sunlight, heat sources. Warranted storage life is 12 months from the date of production without violation of storage conditions. Slight delamination is allowed during the long-term storage, but it does not affect the quality of the material.
Tool cleaning
Work tools and facilities are washed with the solvent P-4 immediately after their usage.
Protective measures
This product is intended only for professional use in industrial facilities in accordance with recommendations given here, as well as safety directions provided to customers along with paint containers. All work, including the application and usage of the product, must comply with Health, Safety and Environmental requirements, all regional standards and instructions.
When painting use personal protective equipment, avoid of getting in eyes, respiratory tracts and on skin. Keep away from open flame.
