     SWD696 Series SH106 Two components

   UV resistance polyurethane system

     ship special UV resistance top coating

  Descriptions               Since the hull above the waterline exposed to suffer the oceanic atmospheric corrosion and sunshine, common anticorrosion coating is easy to be yellowing, pinking, and even cracking, seriously affect the ship's appearance and application. According to this situation, SWD Urethane Co., USA developed a two components ship special UV-resistance top coating. This coating has high weather resistance performance, without color change, powder and peel off after long term outdoor use and sunshine exposure. It is an ideal ship top coating product which has excellent performance of salt spray resistance and anticorrosion.

                                                                                

   

  Characteristics              Film of coating is colorful, full bright, no powder, no yellowing, anti-aging, with excellent weather resistance and gloss color retention decoration. Coating is dense, with high adhesive strength, wear resistance and tensile resistance, nice physical performances, stable chemical resistance, anticorrosion, wet resistance and salt spray resistance performance. Good compatibility with polyurethane, epoxy, chlorinated rubber, alkyd, phenol-formaldehyde and other paintings, recoating interval is unlimited.
