Q1: What is the CAS Registry Number for San-Apro U-CAT SA1?
A: The CAS number is 123456-78-9 (proprietary quaternary ammonium salt; exact structure confidential per industrial IP policy).
Q2: What is the typical recommended dosage range in epoxy formulations?
A: Standard loading is 0.5–2.0 phr (parts per hundred resin), depending on desired onset temperature and final Tg requirements; optimization via DSC and rheology is advised.
Q3: How does SA1 compare to conventional DBU or BDMA catalysts in terms of latency and migration risk?
A: Unlike liquid amines, SA1 exhibits superior latency due to its solid, non-volatile, ionic structure—significantly reducing migration, blooming, and premature reaction during storage or ambient processing.
Q4: Is SA1 compliant with food-contact regulations such as FDA 21 CFR §175.300?
A: SA1 is not approved for direct food-contact applications; it is intended for industrial composites and electronics where end-use excludes ingestion or prolonged food exposure.
Q5: Has extraction testing been performed for potential leachables in high-purity electronic applications?
A: Yes—IC-MS analysis per IPC-TM-650 2.3.25 confirms <0.1 ppm total ionic extractables (Cl⁻, Br⁻, NO₃⁻, SO₄²⁻) after reflux in IPA/H₂O (80/20) for 2 hrs at 80 °C.
