The aesthetics and durability of the coating is integrally dependent upon the application process. Each step and process contribute to making a coating system. This combined coating system must resist weathering and degradation.
The correct choice of chemicals and process plays a major role in the final quality of the coating system. The substrate to be coated must undergo pre-treatment such that the metal is devoid of any dirt, grease and rust and is adequately etched to enable a uniform film build-up of the powder with a strong adhesion to the metal.
The time and temperature of curing should be exactly as specified as the process controls the degree of cross-linking of the resin in the powder. This in turn provides adhesion and durability to the coating.
For products to be used in harsh/marine environments, it is recommended that machining be done prior to powder coating. Doing so allows for all sided coverage of the substrate thereby limiting ingress of moisture and dirt.
Regular cleaning is essential to maintain the appearance of the coating over an extended period of time.
