|---|---|---|---|---|---|---|---|
| FASCAT® 9100 | Monobutyltin oxide / Monobutyltin hydroxide oxide / Butyl stannoic acid (Food Grade) | MBTO / BSA | 2273-43-0 | 218-880-1 | C4H10O2Sn | FDA grade of FASCAT® 4100 that satisfies 21 CFR 175.300, 21 CFR 177.2420, and 21 CFR 175.105. Amorphous white solid with several esterification uses: • synthesis of saturated polyester resins for powder coatings and coil coatings • production of unsaturated polyester resins for gel-coat, sheet molding, and cast molding applications • used to produce polymeric plasticizers. FASCAT® 9100 is an extremely pure butystannoic acid offering industry leading, often undetectable, levels of DBT and TBT species. |  |
| FASCAT® 9102 | Monobutyltin tris(2-ethylhexanoate) (Food Grade) | 23850-94-4 | 245-912-1 | C28H54O6Sn | FASCAT® 9102 is the food grade version of FASCAT® 4102 and it can be used as a catalyst in the production of cross-linked polyester resins for food contact articles intended for repeated use under 21 CFR Sec. 177.2420(b)3. For use as a catalyst in the polycondensation reaction at levels not to exceed 0.2% of the polyester resin. FASCAT® 9102 can be used as a catalyst in the production of polyester resins defined in (b)(vii) of this section provided that the maximum amount of catalyst does not exceed 0.2 percent of the polyester resin under 21 CFR Sec. 175.300. Pale yellow liquid used in the synthesis of saturated polyester resins for powder coatings and coil coatings. Other uses include: • the production of aromatic polyester polyols for flexible and rigid PU foam applications • in ring opening polymerization for polymer production • in the preparation of plasticizers, including dioctyl phthalate • in transesterification reactions, with good catalytic activity at temperatures ranging from 80C to 150C |  |
