Epoxy value derives from the Epoxy equivalent weight (EEW) or Weight Per Epoxide (WPE) and is a measure of the epoxy content of an epoxy resin or epoxy reactive diluent, or glycidyl ether. This is an important parameter as it allows determination of the correct mix ratio of an epoxy system with a curing agent. The epoxide equivalent weight is usually measured first and done by titration. The standard test method is ASTM D1652 though this has been modified by certain sta… WebDesignation D4142 − 89 (Reapproved 2024) Standard Guide for Testing Epoxy Resins1 This standard is issued under the fixed designation D4142; the number immediately following the designation indicates[.] - 123doc - thư viện trực tuyến, download tài liệu, tải
