SILRES® BS 45 is a water-dilutable, solventless emulsion of a silicone resin that serves as a binder in the production of silicone resin emulsion paints and plasters. It is primarily used as the main binder in these formulations, playing a crucial role in their performance. The use of SILRES® BS 45 also contributes to low water absorption, which helps to minimize water ingress and enhance the durability of the coatings and plasters. Additionally, products formulated with SILRES® BS 45 have a low tendency to accumulate dirt and soil, maintaining a cleaner appearance over time.

Application Details
  • SILRES® BS 45 is employed as the main binder in silicone resin emulsion paints and plaster. If formulated properly, the products made with it are characterized by high permeability to water vapor and CO₂, low water absorption, low soiling tendency, a mineral appearance and long life.
  • An excellent beading effect is also achieved if a SILRES® BS Additive is used. Facades must be primed before painting for optimal protection.
  • We recommend high quality SILRES® BS primers.
