This glue is not only clear pure and consistent bottle after bottle but also designed to "wick" better into balsa wood for the strongest bond possible. Each viscosity CA CA+ and CA- has been tested and formulated to achieve the maximum penetration required for its specific application. Cyanoacrylates commonly referred to as "CA" are moisture-activated adhesives stabilized with acids. Water overpowers the small amounts of acid found in the CA so that when CA is applied to a part moisture from the surface of that part and from the atmosphere cause the CA to form a solid or bond in seconds. Some surfaces such as plywood spruce and balsa have a natural acidic content which may blend with the acidic stabilizers in the CAs overstabilizing them.
