National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Cycloaliphatic Epoxy Resin/Anhydride System Usable Up to 150 deg C.

ADA300479

Publication Date	1980
Personal Author	Rindle, J. A.; Newey, H. A.; Chiu, I. L.
Page Count	19
Abstract	We determined the physical and mechanical properties of a cycloaliphatic epoxy resin that was cured using a liquid anhydride plus 1-methylimidazole as a catalyst. The resin system has a low viscosity and a long gel time, making it suitable for wet filament winding. The system cures at low temperatures (100-120 deg C) to yield strong, high modulus resins. High glass transition temperatures (>200 deg C) can be achieved with curing at 150 deg C. The cost of the resin system is low compared to other elevated-temperature resins. Data on aging at 150 deg C in air are presented. jg p.3.
