Description

This hardener is the reactive curing component used with epoxy resins to transform liquid material into a rigid, durable plastic. When combined at the correct ratio, it initiates a chemical reaction that controls pot life, cure time, and final mechanical properties.

Features

  • Available in fast (101), medium (102), and slow (103) speeds
  • HT (High Temperature) version for enhanced heat resistance
  • Slower hardeners generate less heat, ideal for larger pours
  • Faster options suited for small or quick applications
  • Proper mixing ensures consistent curing and optimal results

Instructions

Mix the hardener with the matching epoxy resin at the specified ratio by weight or volume. Stir thoroughly, scraping sides and bottom, until uniform. Pour immediately and avoid exceeding pot life.

Application

  • Work at room temperature and in a well-ventilated area
  • Choose 101, 102, or 103 based on desired working time, or HT for higher heat resistance
  • Avoid moisture contamination
  • Do not mix large masses to prevent overheating
  • Allow full cure before demolding or machining
  • Clean tools before material hardens
