MID-CURE 15 min. epoxy is used in larger areas where more working time is needed. It is more water resistant and can be used as a substitute for QUIK-CURE in most applications. MID-CURE is our most flexible epoxy and is ideal for gluing to fiberglass surfaces. Allow 45 minutes before handling parts and 2 hours for full strength.

Epoxy Tips and Advice

All BSI epoxies are mixed with a 50-50 ratio.

Any scrap material or paper scratch pad can be used as a mixing surface.

We have found, however, that the plastic tops to coffee cans work best due to their outer border and their flexibility, which allows the unused cured epoxy to be released and thrown away.

Squeeze out equal length beads of the desired amount of epoxy, then mix together thoroughly with a popsicle stick or scrap piece of material.

Mix at room temperature and above. In cold weather, epoxy takes longer to cure (too cold and usually they never fully cure).

Acetone or rubbing alcohol works as the best solvent for cleaning epoxy from brushes and unwanted surfaces before it cures. If epoxy gets on surfaces that acetone will attack, use isopropyl alcohol. We do not recommend any additives for thinning epoxies due to their effect on curing and overall strength.

A small amount of CA can be used in strategic locations to hold parts in place while the epoxies cure. The minute designations for epoxies refer to the working time, i.e., the time one has before the epoxies begin to set up after being mixed in a large mass. When spread into thinner layers, the working time in increased significantly. Working time decreases approximately 25% at temperatures above 90 degrees F. Don’t panic if your skin comes in contact with either epoxy or CA.

While contact should be avoided, uncured epoxy can be washed from your skin with soap and water. Allergic reactions are rare. Cured epoxy and CA can be peeled off the skin and usually are gone after a full day of normal activity.

Worked well!

This volume was just what i needed to glue the delaminated fish scale bases on my old cross country skiis .The mid - cure provided enough working time and held well. I skied on them the following afternoon.
Working with epoxy can be messy so watching the You tube videos helped reduce the mess. Lining up your work, and even pressure on many clamps is important.

It seems to be working

Bought this product to repair fine spider cracks in fiberglass. Although it is not as thin when mixed as I would like I did manage to work it into the spider cracks and then sand off the excess.. it seems to be working but the test of time will be the challenge, but so far I am happy
