Wetting & Levelling Agents

Münzing have a range of solutions for addressing wetting and levelling problems; marketed under the EDAPLAN® LA and METOLAT® series. Wetting problems are often expressed in terms of surface defects like craters, fish eyes, orange peel or cissing. Levelling agents tend not to influence the surface tension but rather act at the air-liquid interface to improve characteristics of gloss and slip. A range of different polymer chemistries are available, generally being divided into siloxane-based and siloxane-free, and either non-ionic or ionic. There are a number of considerations to make in choosing the correct product and the Lawrence Industries team are here to help you. Get in touch to discuss your project and find the right solution.


    • Efficient substrate and solid filler wetting.

    • A range of polymer chemistries available, based around ester, acrylic and organo-modified siloxanes. Silicone-free and fluorine-free materials available.

    • Improved levelling with the "LA" series.

    • Easy incorporation into aqueous systems possible.


    • Solve complex surface defect issues such as cratering, cissing, fish eyes and orange peel.

    • Surface tension reduction without intercoat adhesion. Low foaming possible.

    • Excellent compliance levels across regions. Some grades are VOC-free.

    • Indirect food contact approvals on certain grades.

Typical Applications

    • Decorative Coatings.

    • Industrial Coatings.

    • Wood Coatings.

    • Inks

    • Adhesives.

Featured grades with technical datasheets

A brief overview of the key grades is given below. You will find the Technical Datasheets (TDS) available for download. If you are looking for a Safety Datasheet (SDS) or Product Safety Information (PSI) then please get in touch by phone or via the contact buttons at the top of the page.

Should you not find what you are looking for here then please note that we have further grades available besides these. One of our Technical Sales team will be happy to help. All of the sales team are technically qualified and will be able to advise you on which product to choose. You can either call us, email us or fill in a quick form at the top of the page to get us to call you (Request a Callback).
