Description:
Bob Smith Industries BSI-141 Foam-Cure CA Adhesive, 1 oz.
Foam-Cure is a silicone based adhesive that works very well on EPP and EPO foams. It is crystal clear and cures to a more flexible consistency than CA. It is, however, not instant bonding like CA and there is no accelerator to speed its curing. To obtain a faster initial bond when bonding two pieces, Foam-Cure can be applied to one piece and after the two are joined, they can then be pulled apart. After letting it air dry for about ten minutes, Foam-Cure will act like a contact cement when the parts are rejoined, resulting in enough tack strength to allow the next steps of assembly. Full strength is reached in 10-12 hours.
Foam-Cure works with all foams, and will actually bond most other materials. It will bond wood and plastic to foam, and is good canopy glue. Foam-Cure does not, however, cure flexible enough to act as a hinge for aircraft control surfaces. Its limitations occur when bonding large areas of two non-porous materials. Foam-Cure requires exposure to air for drying. If one tried to bond, for example, a half-dollar coin to glass, over 90% of the adhesive would never cure, since the solvent it contains would have nowhere to evaporate. A small amount of denatured alcohol can be mixed into the Foam-Cure to make it thinner.
Directions:
Cut off tip of nozzle. Apply to one part before joining. Use tape to hold parts in place during cure. For faster curing, pull the joint apart and let Foam-Cure air dry for 5-10 min before rejoining the parts. This results in enough tack strength to allow the next steps of assembly. Full cure takes 10-12 hours. Foam-Cure works on all foams, especially on EPP and EPO, and will bond a porous surface to non-porous materials. Foam-Cure is also excellent glue for clear canopies, and will also bond paper. If needed, denatured alcohol can be used to thin or clean up uncured Foam-Cure . Replace cap after use.
