BD 138 High-Bond Anti-Debonding Tile Back Adhesive is a high-performance interface bonding agent formulated from premium polymer emulsion resins and inorganic silicate compounds. Engineered specifically for back-surface treatment of low-water-absorption tiles, including vitrified tiles, porcelain slabs, and heavy natural stone, it creates an impenetrable adhesion bridge for wet-lay installations.
By deeply penetrating dense tile backings and substantially elevating shear and tensile bond strength, BD 138 effectively eliminates chronic engineering issues such as hollow drumming, tile slipping, and premature debonding. It serves as a vital safety-assurance solution for commercial interiors, high-rise residential projects, and heavy-duty tiling tenders.
Prevents Hollow Drumming & Falling Off
Specifically engineered to solve debonding and tile-detachment risks in wet-paste installation, ensuring long-term structural safety.
Advanced Polymer-Silicate Composite
Combines flexible polymer emulsion technology with inorganic silicates to maximize interface penetration and cross-linking adhesion.
Broad Application Versatility
Compatible with a wide variety of dense materials, including vitrified bricks, porcelain tiles, natural granite, and marble slabs across commercial and residential projects.
Exceptional Bonding Strength
Significantly increases pull-off adhesive strength between dense, low-absorption tile substrates and cement-based mortar beds.
