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
Features
  • Improves the storage stability
  • Controls surface dry retardation and keeps the film open longer to ensure deeper penetration of oxygen
  • Can eliminate excessive dry time retardation with phenolics
  • Works synergistically with Borchi® Dragon

Dosage
Borchi® Shield can be added to the system at any stage of the manufacturing process but it is highly recommended to add it as the final addition after driers. Pre-dilution is not recommended. The amount of Borchi® Shield depends on the type of binder and quantity of the driers used. Typical amounts are 0.2 to 1.5 % by weight on total formulation.
