Our factory production aluminate coupling agent can be generic, however, each targeted.
The dosage of coupling agent is not only depend on models and manufactured materials, but also important of filler surface characteristics. For example, surface polarity, specific surface area and moisture content.
Generally speaking, products which are high strength, large specific surface area, strong surface polarity and high moisture content can be into more coupling agent. For example, black aluminum hydroxide is into them 2-3%; Fillers used in injection molding or extrusion of hard and soft products can be into them 0.8-1.2%.
Use our aluminate coupling agent when not to exceed 1.3%, if users used in plastic filler products. (without stearic acid)
