BLUESIL™ BP 9800

BLUESIL™ BP 9800 by Elkem Silicones is an aqueous APE-free polymethylsiloxane resin emulsion. Combined with acrylic or styrene-acrylic dispersions, BLUESIL™ BP 9800 enables the formulation of coatings with high water vapour permeability, notably below the cPVC. In matt systems with high porosity (PVC > cPVC), BLUESIL™ BP 9800 allows good water repellency and high wet scrub resistance. This emulsion is designed for use in facade coatings, to optimize the balance between water repellency and water vapor permeability. Typically, the recommended ratio is between 10% and 50%, relative to the total binder (calculated dry/dry).
