| Superchlon | Recently, developing waterborne paints and adhesives has been required from the standpoint of environmental concerns. Chlorinated polyolefins have also been used in organic solvents such as toluene so far. SUPERCHLON E-723, E-673 and E-503 developed with our special technology are the waterborne chlorinated polyolefin, which shows excellent adhesion to polypropylene substrates and can be used as primers and adhesives. Appearance light brown liquid (dispersion) Solid content (%) 30 pH 7 - 9 Viscosity 5 - 30 (mPa.s / 25degree C) Average diameter of particle below 1 micro meter Film formation a transparent film is formed at room temperature UP Paints Inks Adhesives [Process] PP substrate Surface treatment by IPA Application of E-723 Dried at 80 for 30min. 2K urethane top and clear coat Baked at 80 for 30min. [Result] E-723 Solvent type Adhesion Excellent Excellent Gasoline Resistance >2 hours >2 hours [Testing procedures] Adhesion Coated test panel was cut to make 100sections of checked pattern with 1mm width interval. A cellophane adhesive tape was tightly applied on the checkered pattern, following peeled off at an angle of 180 degree for 10 times. Gasoline Resistance A cross cut was made on the coated test panel which was dipped into gasoline. The time at which any defects occured on the film was measured. UP
