Abstract
The present disclosure provides an organic sulfur acid-free composition containing a benzoxazine, phenolic compound and nitrogen-containing heterocyclic compound. The organic sulfur acid-free composition, upon curing at temperatures as low as 130°-140° C., renders void free cured articles having well balanced thermal, chemical and mechanical properties. The organic sulfur acid-free composition may be used in a variety of applications, such as in coatings, structural and non-structural composites and encapsulating systems for electronic and electrical components.
