Coatings Industry
Special Features and Benefits
The additive provides a medium reduction of surface tension in the coating systems. It increases slip and improves leveling and gloss. Silicone additives prevent the formation of Bénard cells.also improves substrate wetting and anti-blocking properties
Recommended Use
LAG 602 is broadly compatible and suitable for all solvent-borne systems.
Recommended Levels
0.1-0.3 % additive (as supplied) based upon total formulation
The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions
The additive can be incorporated during any stage of the production process, including post-addition.
Thinning before incorporation may make dosing easier
Special Note
Unlike so-called silicone oils, this additive is very user-friendly. However, before use, one should determine in test series whether foam is stabilized in certain systems and check the recoatability and crater development
