Wood Treatment Emulsions

NECOWEL FLE series are based on copolymer resin emulsions of natural fish and linseed oils. These products give excellent wetting and penetration properties on wooden substrates. As such they accentuate natural wood shade and provide early and long lasting water resistance and protection for the wood. Unlike acylic based emulsions these products help to protect from UV light degradation of the wood.

ASK also offer a range of film forming products for fast drying wood primers.


    • Non film-forming and film-forming emulsions for wood protection.

    • APEO-, VOC- and SVOC-free.

    • Low viscosity of the base resin.

    • Open pore wood stain chemistry is based on copolymer resins from natural sources (fish oil and linseed oil).

    • Film-forming products are based on PU-modified alkyds.


    • Excellent wetting and colour enhancement of wood fibres.

    • Outstanding penetration behaviour, good stability and early water resistance. Protects against UV light induced degradation of the wood.

    • Environmentally friendly.

    • Fast drying products available.

    • Simple to formulate with.
