BSI CA Glue Thin, Medium, Thick

BSI CA Glue Thin, Medium, Thick

Insta Cure Super 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.
  • Thin CAs work very well on balsa since they penetrate into the wood and form more than just a surface bond.


  • 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.
  • Unscrew top from nozzle. For finer applications, use the extender tip. Apply Insta-Cure+™ CA to one side of the parts being joined, then hold them tightly together for 5-15 seconds.
  • For larger bonding areas, apply serpentine beads of the CA with enough spacing to allow for the spreading of the adhesive. Insta-Set™ accelerator can be sprayed to cure the CA that oozes from joints.
  • Full strength is reached in three hours.
  • Wipe the nozzle clean before replacing screw-on top. Refrigerate to extend shelf life.
  • Cured CA is stable from -40 to 220° F. Soak extender tip in acetone for cleaning.

Maxi Cure Extra Thick

  • 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.
  • 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.
  • 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.


  • Available in 1/2 oz, 1 oz, 2 oz or 8 oz
