INSTA-CURE Thin is a highly refined CA which, combined with its freshness, gives a guaranteed 2-year shelf life. INSTA-CURE 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 grenadilla since they penetrate into the wood and form more than just a surface bond. Perfect for wicking into wood dust when filling voids and cracks.
