- Recommended Use
Steel surfaces:
- As a primer or intermediate coating in corrosivity categories C2-C4, C5 and CX (ISO-12944-2 / 2018). It is suitable for frameworks of industry building, bridges, conveyors and structural constructions of process indrustry.
Aluminum surfaces:
- • As a primer or protective coating in corrosivity categories C2- C4, C5 and CX (ISO- 12944-2 /2018).
- Compatible Coatings
Depending on the operating conditions the material can be used with different types of coatings:
- Two-component epoxy coatings (2 pack EP) of Rayston.
- Two-component polyurethane coatings (2 pack PUR) of Rayston.

- Drying Time
Standard Grade
Dry Film Thickness 80 µ 5°C 10°C 23°C Surface dry (Dust free) 3 h 2.5 h 1.5 h Dry to touch 8 h 6 h 3 h Min. recoating interval 7 h 5 h 2 h Min. PU overcoating interval 14 h 10 h 3 h Full curing 14 d 10 d 7 d Note: Drying times and polymerization depend from the relative humidity, temperature, ventilation conditions and the thickness of the film. If maximum recoat time is exceeded, it is necessary to make surface roughness with abrasive, rinse with clean water to remove dirt and allowdrying.
The maximum overcoating time is 3 months without roughening provided the surface is free from dirt and grease. If the coating has been exposed to direct sunlight for some time, special attention must be paid for the removal of chalking with the suitable method before the paintingwork.
- Application Data
Mixing Ratio: 5:1
Product Volume Resin 5 parts by volume Curing Agent 1 part by volume Stir resin and curing agent separately (slow stirring) and then mix both components thoroughly with propeller stirrer.Before use the temperature of packaging and material should not be less than 3° C higher than the dew point. Add thinner only after both components have been thoroughly mixed and stir the mixture.
Thinning: If is necessary, the thinner Raystonthinner EP could be add up to 10% by volume.
Note: Adding a thinner will increase the drying time. In the case of using thinner other than recommended, the manufacturer not takes responsibility for any possible reduction in the quality of thecoating.
Cleaner: Raystonthinner EP
Pot life (+23°C): Approx. 1 h after mixing (induction time approx. 15 min)
- Application Method
Application by airless spray, by brush and by roller. For other spraying methods, viscosity correction may be required.
Airless spray: Airless spray with a nozzle tip of 0.013”-0.018” orifice. Spray angle depending on the object to be painted. Pressure ratio of the spray pump must be minimum 45:1. In order to ensure the best possible performance, it is recommendeded that the paint is at room temperature before the application.

Storage & Handling
- Storage & Shelf Life
The product must be stored in original sealed containers. The storage conditions are to keep the containers in a dry, well ventilated space away from source of heat and ignition.
Storage Temperature From 5 to 30°С Component A 1 years Component B 2 years Note: After lasting storage primer shall be stirred thoroughly until its precipitation is spread over the suspension homogeneously. Precipitation in primer does not change its properties or worsen its quality.After the expiration date has passed, it is necessary to check the quality of the paint material.
