Abstract:
Introduction: Specialists in the Coatings industry stress that the
effectiveness of a coating is greatly dependent on the
component’s pre-treatment process. This is a well-respected
fact for some of us in the pre-treatment industry and it is what
makes us tirelessly pursue the advancement of pre-treatment
techniques. The two widely used types of pre-treatment
techniques are mechanical and chemical. Though the
manufacturing industry uses both, mechanical pre-treatment
such as blast cleaning and grit blasting are preferred due
to the environmental concerns associated with the use of
chemicals. Pre-treatment requirements are also applicable
for downstream processes such as thermal spraying and
galvanizing.
