Q1: What is the primary function of TONSIL CO 630G in polymer processing?
A: TONSIL CO 630G is a high-activity, acid-treated bentonite-based catalyst designed to promote controlled crosslinking and condensation reactions—particularly in silicone elastomer and RTV systems—enhancing cure speed, green strength development, and final mechanical performance without excessive exotherm.
Q2: Is TONSIL CO 630G compatible with platinum-catalyzed silicone formulations?
A: No—TONSIL CO 630G is an acid-clay catalyst and is not intended for use in platinum-cured (hydrosilylation) systems. It is specifically formulated for tin-catalyzed (e.g., dibutyltin dilaurate) or amine-catalyzed condensation-cure silicone chemistries where acidic activation supports hydrolysis and silanol condensation.
Q3: How should TONSIL CO 630G be incorporated into a formulation?
A: It is typically added during the high-shear mixing stage under dry or low-moisture conditions to ensure uniform dispersion. Pre-drying the catalyst is recommended if ambient humidity is elevated, and it should be introduced before moisture-sensitive components to avoid premature reaction onset.
Q4: Does TONSIL CO 630G require special storage conditions?
A: Yes—store in a cool, dry place in tightly sealed original packaging. Due to its hygroscopic nature, prolonged exposure to ambient humidity may reduce catalytic activity and affect batch consistency. Avoid storage near strong oxidizers or alkaline materials.
