BSI INSTA-CURE™ Super Thin CA Glue is a fast-acting, ultra-low viscosity cyanoacrylate adhesive designed to wick deep into tight-fitting joints and seams. With its water-thin formula, INSTA-CURE™ flows effortlessly by capillary action and bonds in just seconds, making it ideal for precision work where speed and strength are essential.

Perfect for model building, woodworking, crafts and quick repairs, this adhesive works best on accurately matched parts. Simply hold the components together and apply the glue along the seam, the adhesive will penetrate deep into the joint and cure almost instantly. Thin CA is especially effective on balsa wood, creating a strong internal bond rather than just a surface layer.
