Use of silane coupling agents when producing acrylic resins (copolymerization) Example: Using a silane coupling agent (KBM-503) to modify acrylic resins via radical polymerization Improves adhesion to the substrate and moisture resistance. Prepare a coating liquid by adding 0.5‒2.0 wt% (vs. resin weight) of a silane coupling agent. Water Type
The main advantages of method #II over method #I were: (i) the heat/silane treatment of the hybridized fiber in the internal mixer chamber was omitted, and (ii) the highly viscous polyester polyols coated solid ingredients performed in the high-speed mixing chamber was finally coated with fine talc powder. The talc-coating procedure resulted in ...

Manufacturers of high-performance paint & coating formulations, as well as related applications like adhesives, inks, and sealants, incorporate organofunctional silanes to achieve key performance enhancements. To support the formulator in these applications, Gantrade offers an array of silanes applicable to both water-based and solvent-based systems.
Addition of silane treated talc improved the mechanical properties as compared to TPU/PP/talc blends without chemical modification of talc. The results of strength correlate to the values of the storage modulus and crystallinity of the investigated TPU/PP/talc blends.
TAGS: Adhesion Promoters / Bonding Agent The adhesion is the resistance of the coating to being removed from the substrate. The adhesion promoter for paint is an additive to promote adhesion of the film to the substrate. It usually has an affinity for the substrate and the applied coating and form a permanent and strong bonding.
