Xytu® BT142
Water Repellent for Rock Wool
Water Repellent
BT101 is a silane and modified polysiloxane emulsion for formulating water-based impregnating agents or primers for mineral substrates.
Use BT101 to impregnate mineral substrates such as brick, natural stone and mineral plaster. It is solvent-free, does not affect water vapor permeability, provides high early water resistance and helps prevent efflorescence from soluble salts.
Depending on the absorbency of the substrate, dilute BT101 with water at a ratio of 1:4 to 1:9. Apply the dilution evenly and liberally by brush, roller or immersion. Wet-on-wet application can help avoid missed areas.
