Surface preparation marine coating

Surface preparation, always important in obtaining optimal coatings performance, is critical for marine coatings (see Metal surface treatments). Surface preparation usually comprises about half of the total coating costs, and if inadequate may be responsible for early coating failure. Proper surface preparation includes cleaning to remove contaminants and roughening the surface to faciUtate adhesion. 

Organic zinc-rich Contain high loading of metallic zinc dust in organic binders tend to have better compatibility with topcoat than inorganic zinc-rich coatings more tolerant to variations in surface preparation long service life, especially in marine and other environments. 

Waxes are found in animal and insect secretions and the cell walls of some bacteria. The stored fat of marine animals has a high wax component which forms an energy reserve. Waxes are extracted and used commercially in the preparation of creams, cosmetics, polishes, lubricants and protective coatings for surfaces.
