A-6225 is a proprietary, patent-pending non-halogenated additive utilizing a monofunctional silicone together with a thiol reactive group allowing it to perform multiple functional roles. When used in metal filled and non-metal filled adhesive systems it reduces resin bleed out on a variety of surfaces. When used as a mold release in composite manufacturing the material imparts a residual anti-stiction silicone coating to surface of the parts.
A-6225 is co-curable in both free-radical based and traditional epoxy based polymerization systems. It can also enhance the rheological properties of various filled adhesives.
A-6225 is recommended for use as an additive to reduce resin bleed out specifically on metal surfaces. The recommended addition of the A-6225 to a formulation is between 2% - 5% weight percent of resin. It shows superior bleed control in silver filled formulations and can significantly reduce or eliminate resin bleed out in formulations that contain non-metal fillers such as silica. A-6225 may be applied up to full strength to molds or incorporated at 2 – 4% weight percent in resin formulations to provide mold release and surface anti-stiction properties.
