PLAMCOR®-3
PLAMCOR®-3
Weather-resistant fireproof composition
- Color: Grey
- Packing: Double-packed
Recommended use
Fire protection of metal structures in the atmosphere, including those with high corrosion activity. Provides a fire resistance limit of up to 90 minutes. It is used as a flame retardant layer in complex systems of protective coatings with anticorrosive primers.
MAIN AREAS OF APPLICATION
Industrial construction.
FLAME RETARDANT EFFICIENCY
The fire resistance of the loss of bearing capacity in the case of cellulose burning:
- with reduced metal thickness of 3.4 mm and coat thickness of 2.2 mm – 45 minutes;
- with reduced metal thickness 3.4 mm and the thickness of coating 3.3 mm – 60 minutes;
- with a reduced metal thickness of 5.8 mm and a coating thickness of 4.1 mm – 90 min;
- with a reduced metal thickness of 7.2 mm and a coating thickness of 7.3 mm – 120 min.

EXPENDITURE
The theoretical consumption for a single–layer coating with a thickness of 800 to 1000 microns is 1.0 - 1.3 kg/m2.
SURFACE PREPARATION
Primer coating shall be cleaned from dirt, dust and decreased, shall be free from moisture and shall not have any corrosive degradation, flaking off and cracking.
All areas of damage of primer coating should be repaired.
The thickness of the primer coating should be from 40 to 80 microns. The holding time of the primer coating (at a temperature of (20 ± 2) ° C) before applying the PLAMCOR-3 composition is at least one day.
INSTRUCTIONS FOR USE
Preparation of the composition for use:
- mix thoroughly until homogeneous using mixer;
- when mixing add the hardener (mixing ratio 100:12 by weight), after mixing the composition is ready for use;
- if required prior to application dilute with thinner until working consistency.
The composition shall be applied at temperature from minus 5 to plus 40 °C and relative air humidity of up to 80 %.
Recommended application methods:

The composition shall be applied in 1-5 layers depending on the fire rating requirements and reduced metal thickness.
Drying of the coating is natural, the coating is repairable.
Each subsequent layer shall be applied on expiration of 12 hours after application of the previous layer at temperature from (20±2)°C, at low temperatures holding time shall be increased. At low temperatures, the time of interlayer drying of coatings should be increased.
Minimum holding time of the coat PLAMCOR-3 before application of the top enamel is not less than 24 hours, maximum holding time- not more than 1 month.
The time of complete drying of PLAMCOR-3 at temperatures (20±2)°C is not less than 7 days (depending on the temperature).
Storage and handling
PLAMCOR-3 composition is two-package: basis and hardener packing in metal buckets.
Storage and transportation are carried out in accordance with GOST 9980.5 (in closed premises, ambient temperature from minus 35 to plus 35 °C). During storage, the container should not be exposed to precipitation and direct sunlight.
Warranty storage period in air-tight original manufacturer’s containers is 12 months from the date of manufacture.
PRECAUTIONS
When working with the enamel one shall observe the existing sectoral standard norms and requirements and safety measures as specified on the package label.
Personal protective equipment (goggles, face masks and respirators) shall be used, inhalation of thinners and contact of the composition or its components with skin, ocular mucosa, respiratory channels shall be avoided; use inside the premises is allowed only in case sufficient ventilation is provided.
The composition is classified as a fire-hazardous material.
COMPATIBILITY WITH OTHER MATERIALS
It is applied on the primer coatings of ZINOTAN (TU 2312-017-12288779-2003), ZINEP (TU 2312-022-12288779-2000), ISOLEP-primer (TU 2312-067-12288779-2008), ZFES (TU 2312-004-12288779-99), GF-021 (GOST 25129-82), Penguin Express or other primers in agreement with the manufacturer of the flame retardant.
As a coating layer, it is recommended to use POLYTON-UR (UV) enamels (TU 2312-033-1228779-2002), VINIKOR-62 (TU 2312-001-54359536-2011), as well as polyurethane, vinyl-epoxy or other enamels in agreement with the manufacturer of the flame retardant.
