Abstract
A salicylic acid salt-containing liquid composition useful as an accelerator for a hardener includes a reaction product of (a) salicylic acid; and (b) at least one amine compound compatible with said salicylic acid such that the composition is in liquid form, the composition has a concentration of salicylic acid at from about 35 weight percent to about 55 weight percent, and the composition has a viscosity in the range of from about 500 mPas to about 20,000 mPa-s at 25° C.; a curable epoxy resin composition containing the salicylic acid salt-containing liquid composition accelerator; and a cured product made from the curable composition.
Claims14
A salicylic acid salt-containing liquid composition comprising a reaction product of (a) salicylic acid;
- and (b) at least one amine compound compatible with said salicylic acid, wherein the at least one amine compound comprises 2-methylpentanediamine, a polyetherdiamine, trimethylpentamethylene diamine, or mixtures thereof;
- wherein the resulting composition comprises a liquid;
- wherein the resulting composition has a concentration of salicylic acid at from about 1 weight percent to about 55 weight percent;
- and
- wherein the resulting composition has a viscosity in the range of from about 500 mPa-s to about 20,000 mPa-s at 25° C.
A process for making an accelerator precursor for a hardener comprising admixing (a) salicylic acid;
- and (b) at least one amine compound, wherein the at least one amine compound comprises 2-methylpentanediamine, a polyetherdiamine, trimethylpentamethylene diamine, or mixtures thereof;
- wherein the resulting precursor comprises a liquid;
- wherein the resulting precursor has a high load of salicylic acid at a concentration of from about 1 weight percent to about 55 weight percent;
- and
- wherein the resulting precursor has a viscosity of from about 500 mPa-s to about 20,000 mPa-s at 25° C.
