AM7C81.02 (70 wt% AM0281 in 30 wt% PGMEA) is a hybrid molecule with an inorganic silsesquioxane at the core and organic N-phenylaminopropyl groups at the corners of the cage. It is effective at improving weather-ability of polymers and coatings by reducing water sorption. AM0281 is naturally adhesive, greatly increases performance of BMI and epoxy resins and – as a hindered amine – is an excellent antioxident.
Note: AM7C81.02 (formerly AM0281) is 70 wt% AM0281 in 30 wt% PGMEA (propylene glycol methyl ether acetate). Additional diluents and custom solutions are available upon request.
