            Knot-Filler System Includes:

            2 oz. Black Medium-Thick CA Glue:

            Starbond Black Medium-Thick CA glue is a flexible, rubber-toughened super glue that dries jet black in color. This is ideal for hiding imperfections, filling dark voids, and accenting specific areas in your projects. Along with impact and shock absorbing properties, the black CA retains favorable qualities such as the ability to be sanded down and polished to a high gloss finish. Additionally, when infiltrating fractures, pores, and soft material, the adhesive is able to expand and contract with its surrounding malleable environment, preventing cracking. Starbond Black Medium-Thick CA glue is commonly used in reconing speakers, hobby RC car tires, woodturning inlays, burl, and spalted wood. heavy duty bonding, and filling voids.

            It is important to keep in mind that the colored CA glues have an extended bonding time due to the added rubber compound. Although bonding time is generally 40-60 seconds, it can take much longer to dry when larger volumes of the colored adhesive are applied. For these instances, use of Starbond Accelerator is highly recommended.

            Used In:

            • Repairing and filling cracks, inclusions, voids, and knots in wood
            • Accenting designs on spalted wood
            • Bonding dissimilar materials such as wood, metal, glass and rubber
            • Creating a black accent on projects
            • Gluing R/C Car tires
            • Threadlocking in R/C cars
            • In speaker manufacturing, bonding top plate to frame, spider to voice coil, spider assembly to frame, spider to cone assembly, dustcap to cone, gasket to surround, surround to frame or cone, cone to coil connections, dressing lead wires to cone, and select dustcap applications.

            2 oz. Dark Brown Medium-Thick CA Glue:

            Starbond Brown Medium-Thick CA Glue is for general-purpose use and so much more!  With its “coffee brown” color, there is no need to introduce sawdust and coloring agents to your other CA glues when filling voids! Our BR-500 super glue is the ideal adhesive for bonding close-fitting parts, filling bug holes and knots, and concealing imperfections in wood. We also recommend pairing this glue to highlight and contrast light-colored woods, for perfect inlays, crack repairs, and sanding to a high-polish finish. 

            Used In:

            • Conceal minor imperfections in darker wood such as walnut.
            • Fill cracks, inclusions, voids, and knots in wood
            • Glue and repair in general applications

            6 oz. Starbond Super Glue Accelerator:

            Starbond Super Glue Accelerator, also known as CA glue "activator," is used to significantly increase the drying time of cyanoacrylate super glues. The CA glue accelerant is a solvent based product that can be applied before and/or after CA glue application. Starbond Super Glue Accelerator is commonly paired with thicker viscosity CA glues and black CA glue, as these adhesives take longer to dry. In addition, Starbond Super Glue Accelerator is useful when priming uneven surfaces or material combinations that are harder to bond, and in colder, drier environments where curing time may be delayed. 

            When superglues dry too fast, you'll end up with whitening or "hazing" of the bonding surface. Our specially formulated CA accelerator is made to dry slightly slower than other accelerators on the market to prevent this effect.

            WARNING This product can expose you to chemicals including N,N-Dimethyl-p-Toluidine, which is known to the State of California to cause cancer. For more information go to www.P65Warnings.ca.gov.

            • Used to cure the CA that flows from joints that are being pressed together, greatly enhancing the joints strength
            • When using higher volumes of CA during gap filling applications, bonding time may take much longer, so Accelerator is highly recommended

                              First Time Buyer

                              The sanding discs cut quicker than my current brand and appear to last longer. I purchased these as part of the promo to try out the knot-filler system, which I have used, and it works exactly as advertised. These are great products that I will buy again.

                              I love the knot filler, I have been using it for a few years now. I recommend to everyone I talk to. The sand paper I just started using is great on flat surfaces but when I use it on curved surfaces it falls off of my sander. I have a porter cable and even changed the pad but did not make a difference. It’s the only paper I have had this problem with, otherwise it’s great sand paper.

                              These sanding disc are excellent, I no longer have to sand for hours to get the finish I’m looking for.
