Grade Selection and Processing
HER and HQEE are different positional isomers with different processing behavior. This page identifies solid HER, not the HER-L mixture. Select the grade by hydroxyl value, melting behavior, resin compatibility and processing trials rather than abbreviation alone.
Tell us the resin or prepolymer type, processing method and required end-use properties. Agree the reactive-group balance, working time and cure conditions with your formulation team. No universal dosage or guaranteed finished-product performance is specified here.
Packaging, Storage and Safety
Package size, availability, lead time and shelf life are subject to confirmation in the quotation. Request the current TDS, SDS and available batch COA. Follow the supplied SDS and label for storage, protective measures, transport and disposal. This product page does not replace safety documentation.
