Abstract
The present teachings contemplate a method that includes a step of providing a first amount of esterified reaction product of an acid and an epoxy-based material. The esterified reaction product may be further reacted an epoxy resin to form a polymeric epoxy. The resulting material may have a generally linear backbone, foaming and curing capability and flame retardant properties.
Claims20
A two-part composition comprising:
- a part A comprising an epoxide-functional resin;
- a part B comprising a reaction product of an epoxide and a phosphoric acid that forms a phosphate ester comprising monoesters and diesters wherein the diester is present in an amount that is less than 50% of the amount of monoesters as measured by NMR;
- wherein upon mixing part A and part B, a resulting composition is adapted to cure at room temperature.
