Abstract
The accelerated light aging of three epoxy resins - Araldite AY103/HY951, Devcon 2-Ton, and a non-commercial ultraviolet-curing resin - has been investigated. For samples of appreciable thickness the yellowing predominates at the resin surface. This occurs almost immediately in the case of the very unstable ultraviolet-curing resin but is only seen in the later stages of aging of the two more stable resins. The implication of these findings is that the degree of yellowing of thick casts cannot easily be inferred from the results of aging of thin films. -- AATA
