Abstract:
A metallic fastener has a threaded portion coated with a composition. The composition includes (a) a paraffin wax with a melting temperature in the range of 50 to 70° C. (b) 1 to 5 parts by weight (pbw) of a resin per pbw of paraffin wax, (c) 0.1 to 0.25 pbw graphite per pbw of paraffin wax, and (d) 0.05 to 0.30 pbw of an FDA-approved silica per pbw of paraffin wax. A process for coating the metallic fastener includes: (i) providing the composition as defined above, (ii) maintaining the fastener or bringing it to a temperature in the range of 30 to 70° C., (iii) applying the composition at a temperature in the range of 100 to 170° C., (iv) optionally, removing surplus composition, (v) cooling the fastener to less than 100° C., (vi) finishing the fastener in a water bath, and (vii) drying the fastener.
