Steel surfaces:
- As a single-layer coating in conditions of low and medium atmospheric corrosion categories C2-C3 (ISO-12944-2 / 2018).
- As a top layer (when coating on various types of primers) under the corrosivity categories C2-C4, C5 and CX (ISO-12944-2 / 2018).
- Maintenance coating over old paintedsurfaces.
Non-ferrous and galvanized surfaces:
- As an atmospheric protective coating
Concrete surface:
- In the industry.
- At civil engineering objects.
- Compatible Coatings
Depending on the operating conditions the material can be used with different types of coatings:
- Single pack, moisture cured polyurethane coatings (1 pack PUR) of Rayston.
- Two-component epoxy coatings (2 pack EP) of Rayston.
- Two-component polyurethane coatings (2 pack PUR) of Rayston.

- There is no maximum overcoating interval.
- Rayston Activator may shorter drying time of the coating.
- Dryingand curing time determined at controlled temperatureand relative humidity (RH) 60 - 80%.
- As the relative humidity of the air decreases, the curing time of the coating increases.
- Application Data
Mixing ratio: By volume 4 : 1, By mass 5.2 : 1
Product Volume Resin 4 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 dewpoint. Add thinner only after both components have been thoroughly mixed and stir the mixture.
Thinning: Adding a thinner is not necessary, but if needed Raystonthinner PU may be added up to 10% by volume.
Note: Adding a thinner will increase the drying time. In the case of using thinner other than those recommended, the manufacturer is not responsible for any possible reduction in the quality of thecoating.
Cleaner: Rasytonthinner PU
Pot life (+23 °C): Approx. 1.5 hour after mixing.
- Application Method
Spray Application: Airless spray is the main method of application. For other spraying methods, viscosity correction may be required.
Brush: Application by brush. Recommended for touch-up, stripe coating and small areas.
Roller: Application by roller. Use roller on concrete surfaces.

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 24 months Component B 24 months 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.
