This product provides shelf-stable and non-yellowing adhesion, improving the physical properties of adhesive/sealant systems. Used as a crosslinker or adhesion promoter, it improves water resistance and wet adhesion with good shelf-life. Silanes typically exhibit superior performance only in solvent-rich systems due to storage stability issues, which limits their use in acrylic emulsions. This product effectively eliminates this limitation, enabling future silane crosslinking with shelf-stable properties and, in turn, excellent bonding properties.
This product improves wet and dry adhesion, and adding, for example, 1% (or approximately 0.4% of the dose) significantly improves peel strength without yellowing compared to a non-silane standard. When used as the sole crosslinker, a higher additive may be required, and amounts greater than 2.5% by weight may impact shelf life.
The product was specifically designed to improve bonding properties without negatively impacting the shelf stability of adhesives or sealants. Formulations aged for 4 weeks at 500°C exhibit a similar viscosity change compared to a silane-free standard and significantly less than those currently used with silane.
It is used in water-based coatings, such as acrylics and polyurethanes, as an adhesion promoter and crosslinking agent. It improves the adhesion strength, water resistance, and abrasion and scrub resistance of the coating. Compared to BKTK-2301, this product allows for a longer shelf life in water-based resins.
