Bob Smith Industries, BSI-142 Clear Foam-Cure, Craft Glue, 4fl 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 it’s 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 a 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 no where to evaporate. A small amount of denatured alcohol can be mixed into the Foam-Cure to make it thinner.
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 an 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.
