FINISH CURE 20 Minute Epoxy (13oz)

FINISH-CURE 20 min. epoxy is an excellent, low odor substitute for polyester resins. It can be used for applying fiberglass cloth to wood or by itself to give wood a surface ready for primer and paint. FINISH-CURE can be sanded the easiest of all our epoxies and is excellent for the sheeting of foam core wings. Allow 8 hours for full curing. For best results, FINISH-CURE should be heated to a temperature above 85 degrees F or applying light weight fiberglass, lay cloth on balsa first, then brush on FINISH-CURE. When fully saturated, go over the surface with a heat gun, and then squeegee off excess epoxy with a playing card from an old deck. Heat and remove excess several times for a light weight finish. If room temperature is below 70 degrees F use a heat gun on the surface several times for the next 2 hours. When dry, lightly sand, then fill surface with a low weight spakeling compound, scrapping off excess with a playing card. Sand to a smooth finish ready for primer. For heavy weight fiberglass, apply the epoxy before and after laying down the cloth. FINISH-CURE is best mixed in a disposable cup.

"Also works great as a balsa finish"
skydog (skydog538@gmail.com)
I've used this stuff for small fiberglass projects, including my supersonic rocket project (801 mph!) so I know the stuff is reliable and durable. It uses a 1:1 mix ratio, so no counting drops like polyester resin, and no smell. Working time is adequate, 12-24 hour cure time recommended before sanding. Sands very well wet or dry, does not clog up sandpaper It also works very well for filling and finishing balsa, especially nose cones and transitions, Just brush on a heavy coat, optionally apply gentle heat, and the epoxy will soak in enough that when you've sanded it smooth, you'll still have a harder-than-balsa surface that will be harder to damage. Clean brushes with lacquer thinner or rubbing alcohol.

Information

If CAs are the cure-all for just about all bonding problems, you may be wondering, "Why do I need epoxy?" One primary reason is price. Epoxy costs are about one fourth that of CA. When large objects are being bonded, economics can be a deciding factor on choice of adhesive. The specific characteristics of epoxies also give them advantages in some applications. All our 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. In cold weather, epoxy takes longer to cure (too cold and usually they never fully cure) and becomes more difficult to get out of the bottle, especially if it's less than 1/2 full. The epoxies can be heated in a microwave oven for about 10 seconds so that they flow easier. The heating process, with the caps off, also releases any moisture that can be absorbed by epoxies. Their shelf life, therefore, is virtually unlimited.

Acetone 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. If thin epoxy is required, either use heat or switch to EX-SLOW or FINISH-CURE. Epoxies bond best to clean, textured surfaces. Smooth, non-porous surfaces should be roughened with coarse sandpaper to improve adhesion.

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 (except QUIK-CURE). 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. UN-CURE will debond any body parts that get stuck together if a peeling action (never pulling) doesn't part them.
