- Recommended Use
Steel surfaces:
- Environment classes C2-C4 and C5-I/C5-M on blast cleaned steel surfaces (ISO- 12944-2).
Aluminum and non-ferrous surfaces:
- As a primer or protective coating in corrosivity categories C2- C4, C5 and CX (ISO- 12944-2 /2018).
- As an adhesive layer for epoxy and polyurethane coating systems.
- Compatible Coatings
Depending on the operating conditions the material can be used with different types of coatings:
- Single pack acryl coating (1pack AY) of Rayston.
- Two-component epoxy coatings (2 pack EP) of Rayston.
- Two-component polyurethane coatings (2 pack PUR) of Rayston.

If maximum recoat time is exceeded, it is necessary to make surface roughness with abrasive, rinse with clean water to remove dirt and allow drying.
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: 4:1
Product Volume Resin (Comp. A) 4 parts by volume Curing Agent (Comp. B) 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 no more than 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 the coating.
Cleaner: Raystonthinner EP
Pot life:
- Standard Comp. B: approx. 7 h after mixing
- S-Comp. B: approx. 3 h after mixing
- Application Method
Spray application: Airless spray is the main method of application. For other spraying methods, viscosity correction may be required.
Brush and Roller: Application by brush and by roller.

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 2 years Component B 3 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.
