PURPOSE:To obtain a coating agent for a laver-cultivation net, containing a urethane resin and an acrylic resin as main components, enabling stable adhesion of laver spore to the laver cultivation net, facilitating the seedling collection work in a room and improving the adhesion state of the laver. CONSTITUTION:This coating agent is composed mainly of a urethane resin (preferably polyether or polycarbonate urethane resin having anionic nature and pH7-10) and/or an acrylic resin (preferably having a low viscosity and pH6-9). The agent gives a coating film having excellent adhesivity to a blended net composed of vinylon, nylon, polyethylene, etc., and excellent waterresistance. |
