Q1: What is the primary function of TONSIL CO-N L in polymer processing?
A: TONSIL CO-N L is a high-performance clay-based catalyst designed to promote controlled crosslinking and improve thermal stability in silicone elastomers and certain thermoset systems. It supports efficient condensation curing while helping to minimize post-cure shrinkage and enhance mechanical consistency.
Q2: Is TONSIL CO-N L compatible with platinum-catalyzed addition-cure silicones?
A: No — TONSIL CO-N L is specifically formulated for condensation-cure (e.g., acetoxy or oxime) silicone systems. It is not intended for use in platinum-catalyzed addition-cure formulations, where it may interfere with catalytic activity or cause premature gelation.
Q3: How should TONSIL CO-N L be incorporated into a formulation?
A: It is typically added during the mixing stage under moderate shear, after base polymer and fillers are homogenized. Pre-dispersion in a portion of the polymer or solvent may improve uniformity. Dosage depends on formulation requirements but generally ranges from 0.1% to 2% by weight relative to the total batch.
Q4: Does TONSIL CO-N L require special storage conditions?
A: Yes — store in a cool, dry place in original sealed packaging to prevent moisture uptake. Prolonged exposure to ambient humidity may affect reactivity and dispersion behavior. Avoid freezing and direct sunlight.
