Primers

Primers are used for direct adhesive bonding between substrate and the coating structure which is applied subsequently. For this reason they are applied directly to the wood substrate.  In industrial applications, one must distinguish between hydro UV primers and 100% UV primers which have a solid particle content of 100%.

Hydro UV primers have a solid particle content of between 30 and 80% and therefore need to be pre-dried. They can be pre-dried using any of the commonly available, tried and tested methods on the market (e.g. jet drying, IR dying, cold drying, MOS (microwave) drying, etc.). Alongside its primary task as providing adhesive bonding, Klumpp Coatings Hydro UV primers also prime the wood very well, which accentuates the material’s naturalness. Depending on the primer system, colourations are also possible to make colouristic adjustments (achieve equalising effects).

100% UV primers (high-solid) can be used alternatively, should the coating technician not have a drying machine available. They have no, or next to no volatile matter and can be hardened with UV rays immediately after application.
