Hold it Right There! How Long Does Epoxy Take to Cure?

By November 4, 2012Repairs, Uncategorized

Hold it right there, Mr. Impatient. Wait another minute. Or is it an hour? Days? As it stands, curing times for different epoxy pastes and putties vary quite widely. As much as your fingers ache and yearn to pick up (or step on … or throw) what you’ve fixed and test it out, you might be jumping the gun. The strength of an epoxy hold often depends on how well it cures. You might want to resist temptation a little longer!

Looking for a Quick Fix?

It’s true that most of us are looking for something quick … because if it takes a long time, we just don’t want to bother. And we’re OK with that! PC Putty Epoxies are just the solution when you need a quick fix. Putties are hand moldable and quick setting, they boast a short work time and fast cure time. They are just what you need if you want to get back to the game before half-time is over!

Epoxy Rule of Thumb

A general rule of thumb for epoxy curing is this: if your project is important, cure it warm, slow, and long. Cold curing doesn’t hold strength very well. A good bet is to allow 72 hours of setup time for full strength building of adhesive bonds to form and mature. It is most critical to allow jobs subject to pressure or stress a full curing time.
