Description:
1. Produced with advanced hue and partical size control technologies, R-618 is a kind of high-end rutile TiO2 pigment with good chalking resistant property. Coated with zirconia and alumina in an inorganic manner and modified with special organic finishing agent on the surface, it can be widely used in the fields that have special requirements on weather resistance.
Major characteristics:
◇ good weather resistance: it can be used under high temperature, highlight and severe salt mist environment without yellowing and chalking;
◇ excellent dispersibility: good wettability and easy to grind;
◇ low oil absorption: retaining good fluidity during the utilization of paint and ink.
Application fields:
◇ all kinds of decorative paints(especially good weather resistance required); ◇building paint ( for outdoor use);
◇ top-coat for automobile;
◇ plastic section bar.
