TEKNODUR 3510-23

Two-component topcoat.

Two-component reaction drying topcoat for synthetics and MDF.

Resistant to weak acids, bases, and solvents. Re-coating must be carried out within max. 36 hours, as otherwise poor adhesion between the layers may be the result. Application of silk screen-printing must be carried out within 24 hours to obtain sufficient adhesion. For internal use if an abrasion resistant and robust surface is required.


MIXING OF THE COMPONENTS: To achieve a satisfactory result, it is important that the hardener is mixed correctly. Inadequate stirring or incorrect mixing ratio results in imperfect curing and impaired film properties. Within the first 15 minutes following the addition of hardener, the viscosity increases. Final adjustment of the spraying viscosity must be made after this time.

Application conditions

The surface to be treated must be dry. During the application and drying period the temperature of the ambient air shall be above +10°C and the relative air humidity below 80%. Adhesion and compatibility to plastic types should be tested before application as variation may occur, dependent upon the type of plastic.
