bond™ is a unique low melting temperature adhesive plastic. bond™ can be used to secure coral to rockwork or to fuse rockwork together for more stable foundations in reef aquaria. bond™ is completely non toxic and inert with no impact on aquarium chemistry. bond™ has a much lower melting temperature than similar products making it safer and easier to work with. If necessary, bond™ can be reheated and reworked multiple times until desired results are achieved.
