To ensure a successful long term performance under severe conditions, preparation of SSPC-SP 5, or White Metal Finish with an appropriate angular profile is recommended.
However NACE 12/AWS 2.23M/ SSPC – CS 23.00 specifies a minimum surface preparation of SSPC-SP-10, or near-white-metal finish obtained by blasting.
A minimum of 2.5 mils of a sharp, angular profile depth is required. A high spray velocity is essential to penetrating the anchor profile valleys and developing superior splat adhesion. Particles are locked into the ridges of the profile peaks upon cooling.
