AKRYL 2K PU Enamel
A coloured protective and decorative layer for primed metal. In the tested system it is applied after the primer surfacer and before the polyurethane clearcoat.
TypeTwo-component
LayerEnamel
Base : hardener20 : 6 by mass
Thickness40-50 µm
About the material
The colour layer in the coating system
The enamel is based on acrylic resins with pigments, fillers, organic solvents and a hardener. The presentation specifies use on primed metal surfaces of vehicles and metal structures.
Material selection and the application process depend on the substrate, previous coats and service conditions. Request the current TU specification and instructions before use.
Purpose
Where the material is used
The list is based on the AKRYL presentation. Suitability for a specific project is confirmed through technical selection.
Urban and commercial vehicles
Coating primed metal surfaces using an agreed application procedure.
Metal structures
Suitability is determined by the substrate, environment, required colour and application conditions.

These are individual material specifications, not test results for the complete system. Requirements and test methods must be checked against current technical documentation.
Preparation
What to check before application
Describe the object and primer
Specify the metal, previous coating and service conditions.
Agree the colour
Confirm the required shade and colour availability before ordering.
Check the system
Confirm compatibility and application conditions using the current TU specification and a trial on the project.
Components, application and storage
| Supply set stated by the manufacturer | Enamel base, hardener and thinner. The set composition and mass are specified in the order. |
|---|---|
| Component B | AKRYL 2K PU Hardener, TU 24.72.28-056-49740748-2025 |
| Thinner | PU Akryl, TU 20.30.22-055-49740748-2025; no more than 10 % by mass. |
| Mixture preparation | Stir the base and hardener separately first. After mixing, allow 10-15 minutes before application. |
| Application | Air or airless spray; a brush is permitted on areas smaller than 1 m². One or two coats; consumption is calculated for a two-coat dry film of 40-50 µm. |
| Conditions | Relative humidity no more than 80 %; surface temperature at least 3 °C above the dew point. Agree the minimum application temperature with the technologist using the current instructions. |
| Intercoat interval | 6-24 h; after 24 h the surface must be sanded. Check the conditions against the project requirements. |
This information is taken from the manufacturer's materials and does not replace the current application instructions. Request them for the selected material and project before application.
Theoretical consumption is given for the specified coating thickness. Actual consumption depends on application methods and conditions, roughness, object geometry and process losses.
Request AKRYL 2K PU Enamel
Specify the object to be coated, substrate material, service conditions, required colour, area and application method. We will clarify technical documents and supply terms.
Individually or as a systemIndividual materials from the 2K system can be requested separately. Compatibility with other coatings must be checked.
Questions
What to clarify before ordering
Is a primer required before the enamel?
The presentation specifies enamel application to primed metal surfaces. The preparation procedure is agreed for each project.
Can the enamel be purchased separately?
Yes, you can request the material separately. Compatibility with a primer and clearcoat from another system must be checked.
Which colours are available?
Colour is clarified when you enquire. The current source does not include a public list of confirmed shades.
What is the mixing ratio?
For this grade, the presentation specifies a base-to-hardener mass ratio of 20 : 6.
What are the enamel application conditions?
Agree the minimum application temperature with the technologist using the current instructions. Relative humidity must not exceed 80 %, and substrate temperature must be at least 3 °C above the dew point.
How is the enamel applied?
Airless and air spray are listed; a brush is permitted on areas smaller than 1 m². Select the working viscosity for the application method.
When should the next coat be applied?
The presentation specifies an intercoat interval of 6 to 24 h; sanding is required after 24 h. Check the exact conditions against the TU specification and project requirements.
