NECOWEL Architectural

Modified Alkyd Emulsions

NECOWEL architectural emulsions are based on modified alkyd resins. Cationic modification gives them excellent stain blocking properties. Stain blocking primers and coatings can be formulated with a wide range of additives due to the neutral pH of the emulsion. PU-modified grades give excellent flow and wetting properties, allowing for high gloss finishes with low yellowing and good weathering. This makes them ideally suited for formulating trim paints and high gloss wall paints.


    • Aqueous alkyd emulsions that have been cationically modified or PU-modified.

    • Medium oil length.

    • APEO- and VOC- free.

    • Neutralized with ammonia.

    • Solids content typically around 40% by weight.


    • Cationic modification on certain grades gives high performance stain blocking for water soluble substrate contaminants.

    • Neutral pH allows for a wide formulation latitude.

    • Environmentally friendly.

    • PU-modified grades have a high gloss and excellent flow with no additional associative rheology modifier needed.

    • High weathering stability and low yellowing with the PU-modified grades.

    • Excellent substrate wetting properties.

Typical Applications

    • Stainblocking primers and coatings.

    • Trim paints and general wall paints.
