Special features and benefits
The additive provides a strong reduction in the surface tension of coating systems. It therefore especially improves substrate wetting and prevents cratering. Surface slip and gloss are also increased. BYK-313 also provides very good leveling properties, even with thin layers. BYK-313 is a thermally stable 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. The additive is HAPS- and aromatic-free.
Recommended levels
0.05 - 0.5% additive (as supplied) based on the total formulation. 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. However, before use, one should determine in test series whether foam is stabilized in certain systems. Similarly, the recoatability, the migration of the silicone in stacked sheets as well as cratering should be checked.
