Calcium carbonate and soluble glass and so on were confected as alkaline antifouling agent. The Infrared Spectrometry results showed that 2275-2250 cm~(-1) diagnostic absorb wave crest in part A and 3390-3200 cm~(-1) in part B and 1730 cm~(-1) in coating film strongly proved polymers reacted just as the reacting mechanism, that means polysiloxane which offer low-surface-energy property linked Polyurethane system by —OH groups reacting with —NCO groups. Relative molar mass of part A and part B was determined by Gel Permeation Chromatography and the results were appropriate. Surface-energy was determined and results were between 33.6-47.17 mN/m and it increased when alkaline antifouling agent was put into the coating. Alkaline antifouling agent was releasing steadily when the coating film was dipped in seawater. As time gone, the pH value of seawater was increasing. Solubility parameter and results showed that there was no corrasive phenomenon between the polyethylene strand and the coating.
