BS 2410 A is particularly suitable to permeate through paper backer fibers and does not affect adhesion properties to gypsum. It is a highly active epoxy functional silicone macro-emulsion designed for use in the hydrophobation of paper backer for gypsum board. BS 2410 A has little, or no shade change and no concerns about the yellowing effect.

  • Empirical formula Polymethylsiloxane with funcitonal groups


BS 2410 A improves moisture and mildew resistance by improving hydrophobicity with a noticeable sheeting effect. These effects are fast and long lasting.  As a rule, no adverse effect on the shade or color fastness properties of colored goods is observed.


BS 2410 A has a shelf life of at least 180 days if stored in originally sealed containers at 25 °C or 70 °F. Emulsions showing signs of creaming should be agitated before use to assure uniform consistency. If the material is kept beyond the recommended shelf life, it is not necessarily unusable, but quality control should be performed on the properties relevant to the application.
