BSI 201 QUIK-CURE 4.5 oz. (128g) 5 min. epoxy cures a slightly flexible consistency. This lack of brittleness allows it to form a lasting bond in areas subjected to high vibration or stress. QUIK-CURE™ shouldn’t be used in areas that are subject to long-term immersion in water; however, it works fine for the internal structure of wood-framed boats. QUIKCURE™ is our only epoxy on which you can apply polyester resins. It can be mixed with microballoons to form a quick-setting putty. Items bonded with QUIK-CURE™ can be handled after 15 minutes. Full strength is reached in 1 hour.
BSI 203 MID-CURE 4.5 oz. (128g) 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 fibreglass surfaces. Allow 45 minutes before handling parts and 2 hours for full strength.
BSI 206 SLOW-CURE 9 oz. (256g) 30 min. epoxy works best for forming reinforcing fillets on joints. It has the highest strength of our epoxies. It is waterproof and more heat resistant. SLOW-CURE™ can be used for bonding if you’re willing to wait overnight. Fillers such as microballoons can be mixed with SLOW-CURE™ and FINISH-CURE™ to form a putty-like consistency. Such fillers will usually decrease the working time by about 25%. Bonded objects can be handled after 8 hours and the cured epoxy reaches full strength within 24 hours.
BSI 209 FINISH-CURE 4.5 oz. (128g) 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.
