Link-Shine AP68
High-Performance Silane Adhesion Promoter – For Aluminum Alloy, Sealants, MS Adhesives
Product Overview
Link-Shine AP68 is a high-performance silane adhesion promoter, specially designed for aluminum alloy surfaces. It significantly enhances the bonding strength of sealants, MS adhesives, structural adhesives, and other industrial adhesives. The silane methoxy (Si-OCH₃) groups chemically bond with aluminum surfaces, improving adhesion, weather resistance, and moisture-heat durability.
