Insta-Cure CA (2 types)
CAs have become the adhesive of choice for most hobby and household applications. High quality CAs such as Insta-Cure™, when used properly, form bonds that in many cases are stronger than the material that is being adhered. Insta-Cure™ is a highly refined CA which, combined with its freshness, gives a guaranteed 2 year shelf life. CAs are reactive monomers that chemically link (polymerize) when pressed into a thin film. Ideal for tacking fins or other parts into place to get perfect alignment before adding epoxy.
Insta-Cure™ Thin has a water-thin viscosity that wicks deep into joints by capillary action and cures in a matter of a few seconds. Surfaces to be bonded must be tight fitting and should be held together while you apply the CA around the edges of the seam. At the moment CAs cure, they give off a vapor that can irritate the nose and eyes, so be prepared.
Insta-Cure+™ Thick is a higher viscosity CA for loose fitting joints in which the adhesive must bridge gaps. Normally, the thicker CA is applied to one surface and then the parts are held tightly together for about 5 to 15 seconds. For large surface areas, including those with close fitting joints such as laminations, Insta-Cure+™ should also be used. To prevent premature curing, don’t spread the glue into a thin film. Lay down a serpentine bead with about 1" separations on one surface, then assemble the parts, letting the pressure spread the CA out.
