BYK-349

Silicone
MITM02238
ITM04006, ITM04007

Silicone surfactant for aqueous coatings, adhesives and maintenance products with a considerable reduction in the surface tension and therefore good substrate wetting.

Applications

Coatings Industry

The additive produces a significant decrease in the surface tension in aqueous coatings and therefore particularly improves substrate wetting and leveling. It only marginally, if at all, stabilizes foam and the recoatability is not impaired. The additive does not increase the surface slip. If a greater surface slip is required, we recommend that it is combined with a polysiloxane such as BYK-333.
Recommended Use
  • Automotive coatings
  • Architectural coatings
  • Wood and furniture coatings
  • Industrial coatings
  • Can coatings
  • Coil coatings
  • Protective systems
  • Leather finishes

 

Adhesives & Sealants

BYK-349 is a highly effective silicone surfactant. The additive causes a considerable reduction in the surface tension in aqueous adhesive systems. It thereby improves the wetting of critical substrates.

Care Products and Polishes

BYK-349 is a highly effective silicone surfactant with a considerable reduction in the surface tension to improve the substrate wetting and leveling in aqueous maintenance products. It only marginally, if at all, stabilizes the foam, does not impair the subsequent layer and does not increase the surface slip.
