Borchi^® Shield

Borchi^® Shield: MEKO Replacement Anti-Skinning Agent

Borchi^® Shield is a MEKO-free anti-skinning agent for use with alkyd coating technology, which includes traditional cobalt driers in solvent-based oxidatively cured coating systems. This solution is specially designed for use with Borchi^® Dragon high-performance cobalt-free catalyst. It is a sustainable anti-skin solution that is specifically designed to work well in high solids, long oil resin systems. Borchi^® Shield is an amino / oxime compound dissolved in fatty acid ester. This solution has minimal impact on dry times and provides excellent storage stability.  

MEKO Regulatory and Sustainability Concerns in Paint and Coatings

MEKO (Methyl-ethyl-ketoxime = 2-Butanone oxime) is used in anti-skins due to its ability to prevent skin formation in closed containers. It has little or no effect on drying performance. MEKO works well with cobalt primary driers in alkyd paints.   So what’s the problem with MEKO?   The European Union, the Canadian government, and other nations have proposed the reduction of MEKO levels in alkyd paints. Cobalt driers have also faced regulatory pressures in the coatings industry. Sustainability is increased in alkyd paints with the use of MEKO-free anti-skins and high-performance cobalt replacement catalysts.

MEKO-free anti-skinning agents sustainably reduce in-can skinning

   

Benefits of Borchi^® Shield Anti-Skinning Agent

MEKO replacement anti-skinning agents like Borchi^® Shield are specially designed to prevent skinning in high solids and long oil systems with reduced VOCs. This solution is compatible with high-performance cobalt-free driers – specifically Borchi^® Dragon high-performance catalyst for high solids, long oil alkyd coatings.    

In-can skinning is reduced without significantly affecting dry times or storage stability when using Borchi^® Shield anti-skin with Borchi^® Dragon cobalt-free high-performance catalyst
