Fouling is a major problem for the performance and maintenance of boats. The rapid accretion of the first biofilm layer (approximately 1 mm) already results in a 20% increase in drag, rising to 60% if molluscs are present. Uniflow engineers decided to change the rules in dealing with fouling. Paints are very harmful for the oceans and for man. In addition, their effectiveness rapidly diminishes over time. Silikon is a three-layer polymer self-adhesive film with very high glide performances while with a very significant antifouling action. The principle is based on the very low surface tension and smooth finish of the upper layer in contact with the water, reducing considerably any loss of momentum. An increase in drag is one of the characteristics of antifouling paints, which degrade over time. The hull becomes increasingly rough and laden with algae and mollusks. Silikon Silikon is the best product for preserving both high- performance glide capacity and an optimum antifouling function without biocides
