Product description

Starbond KBL-500 Black Heavy Medium CA glue is a flexible, rubber-toughened super glue that dries jet black in color. The KBL-500 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 KBL-500 Black Heavy Medium 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.

Awesome PRoduct
Thick enough to fill voids without running all over your workpiece. Quick drying but using the accelerator gets you back to work instantly. Excellent results when used with carbide turning tools. Thanks Starbond!

Saves time!
This is exactly what I needed in lieu of epoxy for my project this time. I may be switching over completely now!

More Color Options
I would only like to see more color options...possibly some vibrant colors to add a unique flare to wood projects. Tourquoise or copper, bright red or blue?
