EPIKURE™ Curing Agent 3046

 

 

Product Description

 

EPIKURE™ Curing Agent 3046, an aliphatic amidoamine, is in the same class as EPIKURE Curing Agent 3055. The useful combining ratio with EPON™ Resin 828, varying from 35 to 100 parts per 100 parts resin, makes EPIKURE Curing Agent 3046 a very versatile ambient temperature curing agent.

General Information

 

EPIKURE Curing Agent 3046 provides a working life of several hours at normal room temperatures, yet cures to handling strength in thin sections overnight at temperatures above 60 °F. Good strength properties are generally achieved within three days and an essentially complete cure is obtained within two weeks at room temperature. The gel times and maximum exotherms for several formulations cast at normal room temperature at a thickness of 1/2 inch are listed in Table 1.

 

Optimum properties are obtained at 50 parts per 100 parts resin in combination with an unmodified epoxy resin such as EPON Resin 828. Although the heat deflection temperature is improved with an elevated temperature post cure, most other properties are as good or slightly better in a room temperature cure; impact resistance is particularly high. The effect of curing agent level, reactive diluents and cure schedule on properties is illustrated by data presented in Table 2.

Safety, Storage & Handling

 

Please refer to the MSDS for the most current Safety and Handling information.

 

Please refer to the Hexion web site for Shelf Life and recommended Storage information.

 

This curing agent product may crystallize after extended storage times. It can be reconstituted by gentle warming of the entire container and its contents to approximately 80°C (176°F) until all visual evidence of crystallization has gone away. Upon cooling to normal ambient temperature conditions the product will regain its original liquid state physical properties.

 

EPIKURE Curing Agent 3046 should be stored in tightly sealed containers, in a dry location at normal room temperature. Care should be taken to avoid storage environments resulting in moisture contamination. Exposure to moisture causes an increase in viscosity and reactivity, the degree of increase depending on the amount of moisture which has been absorbed.

 

Exposure to these materials should be minimized and avoided, if feasible, through the observance of proper precautions, use of appropriate engineering controls and proper personal protective clothing and equipment, and adherence to proper handling procedures. None of these materials should be used, stored, or transported until the handling precautions and recommendations as stated in the Material Safety Data Sheet (MSDS) for these and all other products being used are understood by all persons who will work with them. Questions and requests for information on Hexion Inc. ("Hexion") products should be directed to your Hexion sales representative, or the nearest Hexion sales office. Information and MSDSs on non-Hexion products should be obtained from the respective manufacturer.
