NSI Superbond Primer is the original nail primer formula used in the nail industry. Superbond is a methacyrlic acid nail primer that slightly etches the nail plate to help with adhesion. All acid-based primers have a very high freezing point; therefore it does not take extremely cold temperature to make it freeze. By simply allowing Superbond to return to room temperature, it will be ready for application without losing any of its effectiveness.
