The difference between this and Dowsil 789 is this one is acetoxy cure and is more rigid .. which means it will smell like vinegar while drying up. It dries faster than 789 which does not smell like vinegar while drying up. Some people have complained that the 789 is very flexible. This one is rigid. If you build an aquarium with this the glass panes won’t move much. This 100% silicon is a better choice for aquarium building. 789 is better suitable to flexible joints.
