Applications

Antioxidant 1726 is a multifunctional hindered phenol antioxidant that can be applied to a variety of polymers. It is especially recommended for use in adhesives, such as hot melt adhesives (HMA) based on SBS or SIS, solvent-based adhesives (SBA) based on natural rubber, chloroprene rubber, etc., and water-based adhesives (WBA). 1726 is also recommended for use in block copolymers, such as SBS, SIS, and sealants. Since 1726 has low volatility, no color stains, and is resistant to extraction, it can provide excellent thermal oxidative aging protection for polymer materials. Since 1726 contains both primary antioxidant and secondary antioxidant structures in its molecules, it can provide thermal stability and processing stability for polymer materials at the same time. If necessary, 1726 can also be used in combination with primary antioxidants, secondary antioxidants, and light stabilizers.

Storage

Antioxidant 1726 is stable in nature and has no special requirements; pay attention to moisture-proof and avoid high temperature.
