BYK-310

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. BYK-310 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 olvent-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. The optimum dosage should be determined by application-related test series.
Incorporation and processing instructions
The additive can be incorporated during any stage of the production process, including post-addition.
Special note
Unlike so-called silicone oils, this additive is very user-friendly. Nevertheless, it should be determined in series testing, whether foam is stabilized in certain systems. Similarly, the recoatability, the migration of silicone in stacked sheets as well as cratering should be checked.

Adhesives and sealants
Special features and benefits
BYK-310 is a highly effective silicone additive. It provides a strong reduction of the surface tension, thereby improving the wetting of critical substrates.
Recommended use
Recommended for improving the substrate wetting of epoxy-based adhesive systems.

The above recommended levels can be used for orientation. The optimum dosage should be determined by application-related test series.

Incorporation and processing instructions
The additive can be incorporated during any stage of the production process, including post-addition.
Special note
Unlike so-called silicone oils, this additive is very user friendly. Nevertheless, its influence on the adhesive properties should be checked.

Ambient-curing Plastic Systems
Special features and benefits
BYK-310 is a highly effective silicone additive. It provides a strong reduction of the surface tension, thereby improving the wetting of critical substrates. It also exhibits high temperature stability.
Recommended use
Recommended for improving the substrate wetting of ambient-curing epoxy-based resin systems.
Recommended levels
