Applications

Coatings Industry

Special Features and Benefits

The additive provides a strong reduction of the surface tension of coating systems. It therefore particularly improves substrate wetting and avoids cratering. Surface slip and gloss are also increased. LAG-604 is a thermostable silicone additive which, in contrast to conventional silicones, shows no thermal decomposition at temperatures between 150 °C and 230  °C. Consequently, when re-coating, no loss in adhesion and no surface defects occur, which can be caused by the decomposition products of conventional silicones above 150  °C.

Recommended Use

The additive is particularly recommended for all solvent-borne coatings and can also be used in solvent-free systems.

Recommended Levels

0.05-0.3 additive (as supplied) based upon total formulation. In solvent-free systems up to 0.5 .

The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.

Printing Inks

Special Features and Benefits

The additive provides a strong reduction of the surface tension of the systems. It therefore particularly improves substrate wetting and avoids cratering. Surface slip and gloss are also increased.

Recommended Use

The additive is particularly recommended for all solvent-borne coatings and can also be used in solvent-free systems.

Recommended Levels

0.05-0.3 additive (as supplied) based upon total formulation
