Q
do i need to use a hardener when using epoxy
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Yes, using a hardener with epoxy is essential for ensuring the mixture cures properly. Epoxy resins are designed to react chemically with a hardener, initiating a cross-linking process that transforms the liquid resin into a solid state. Without a hardener, the epoxy resin would remain tacky or liquid, failing to achieve the desired strength and durability. The ratio of resin to hardener must be carefully measured according to the manufacturer's instructions, as incorrect proportions can lead to inadequate curing, affecting the performance and final properties of the epoxy. Thus, for any application that requires the full benefits of epoxy, including bonding, coating, or encapsulating, using a hardener is not optional but a fundamental step in the process.
