20110065837 | LOW TEMPERATURE CURABLE EPOXY COMPOSITIONS CONTAINING PHENOLIC-BLOCKED UREA CURATIVES - A heat curable epoxy composition comprising the contact product of an epoxy resin, an epoxy curing agent and an accelerator for the epoxy curing agent, the curing agent or the accelerator comprising the reaction product of (a) a phenolic resin and (b) a urea compound which is the reaction product of an isocyanate and an alkylated polyalkylenepolyamine having one primary or secondary amine and at least two tertiary amines of the general formula: | 03-17-2011 |
20110065958 | Low Temperature Curable Epoxy Compositions Containing Urea Curatives - A heat curable epoxy composition comprising the contact product of an epoxy resin, an epoxy curing agent and an accelerator for the epoxy curing agent, the curing agent or the accelerator comprising a urea compound which is the reaction product of an isocyanate and an alkylated polyalkylenepolyamine having one primary or secondary amine and at least two tertiary amines of the general formula: | 03-17-2011 |
20120077943 | Low Temperature Curable Epoxy Compositions - A heat curable epoxy composition comprising the contact product of an epoxy resin, an epoxy curing agent and an accelerator for the epoxy curing agent, the curing agent or the accelerator comprising the reaction product of (a) a phenolic resin (a) of general formula: | 03-29-2012 |
20140243456 | Anhydride Accelerators for Epoxy Resin Systems - Carboxylic acid salts of tertiary amines for use as an accelerator for an anhydride based epoxy curing agents are disclosed. The disclosed carboxylic acid salts of certain tertiary amines are latent anhydride accelerators and enable epoxy resin curing when heated to an elevated temperature (e.g., an onset temperature of greater than about 50° C.). | 08-28-2014 |
20140303342 | One Component Epoxy Curing Agents Comprising Hydroxyalkylamino Cycloalkanes - Liquid epoxy curing agents that have improved latency over conventional liquid curing agents while retaining the physical properties of the cured material are disclosed. These liquid curing agents can be used for curing epoxy resins, or in combination with dicyandiamide (DICY) based curing agents in order to accelerate DICY curing. | 10-09-2014 |
20150025201 | AMINES AND POLYMERIC PHENOLS AND USAGE THEREOF AS CURING AGENTS IN ONE COMPONENT EPOXY RESIN COMPOSITIONS - The disclosure relates to solving problems associated with conventional latent epoxy curing agents by providing a new class of latent epoxy curing agents. In particular, the disclosure relates to epoxy curing agents with improved storage stability and low use level (e.g., less than about 10 wt % relative to the epoxy compound) by forming solid solutions of certain classes of amines in polyphenolic resins. | 01-22-2015 |
