Maxi-Cure extra thick CA is the best CA for most plastics, including GE's Lexan MAXI-CURE is the best choice for plastic model assembly. When used with INSTA-SET, it works better than any putty for modifying or filling voids. It can be carved with a knife or razor blade and sanded and feathered to form a finish indistinguishable from plastic. MAXI-CURE bonds fiberglass, hardwood, metal and rubber better than any other hobby adhesive. For gluing to the inside, clothtextured surface of fiberglass, scrape the area to be bonded with a razor blade or coarse sandpaper before using MAXI-CURE or any other adhesive. It also is best for bonding the tires for R/C cars. MAXI-CURE has proven to be very popular in the archery business for the fletching of vanes onto aluminum and carbon arrow shafts. Along with being the strongest, MAXI-CURE is usually the least expensive option for this application. No. MT111 1/2 oz. ABOUT CYANOACRYLATES: Cyanoacrylates (CAs) have become the adhesive of choice for most hobby and household applications. High quality CAs such as MAXI-CURE, when used properly, form bonds that in many cases are stronger than the material that is being adhered. MAXI-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. The very thin layer of water moisture present on most surfaces acts as an alkali, or weak base, which is the catalyst that results in bonding; however, the presence of detectable amounts of water usually degrades the performance of CAs.
