Q1: What is the primary function of TONSIL APT-mX L in polymer processing?
A: TONSIL APT-mX L is a highly active, low-ash, acid-treated bentonite-based catalyst designed to promote controlled crosslinking and improve thermal stability in silicone rubber formulations, particularly during high-temperature vulcanization.
Q2: Is TONSIL APT-mX L compatible with platinum-catalyzed addition-cure silicones?
A: Yes — TONSIL APT-mX L is formulated to be non-interfering with platinum catalysts and is commonly used as a co-catalyst or reinforcing aid in addition-cure systems without causing premature inhibition or scorch.
Q3: How should TONSIL APT-mX L be incorporated into silicone elastomer compounds?
A: It is typically added during the high-shear mixing stage after base polymer incorporation, ensuring uniform dispersion. Pre-drying is not required under standard ambient conditions, but storage in a cool, dry environment is recommended to maintain optimal reactivity.
Q4: Does TONSIL APT-mX L affect the rheology or processing behavior of uncured silicone compounds?
A: Yes — it generally imparts mild thixotropic character and improves green strength without significantly increasing viscosity at typical use levels, supporting better mold fill and reduced sag in high-aspect-ratio parts.
