Applications

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
