There are two types of styrene-acrylic emulsion,GHT-1 and GTH-1D.GHT-1 is styrene-modified acrylic esters copolymers resin emulsion, which has excellent water-resistance and alkali-resistance, and doesn’t become white when dipped into water. The latex paints compounded by GHT-1 have good stability and adherence, excellent swab-duration and weather-duration. It is suitable for producing exterior and interior wall latex paints, natural stone paints and natural stone paints compounded with silicon collosol, and middle coatings for thick paints. GHT-1D especially suits to produce exterior and interior latex paints of high pigment volumetric concentration. GHT-1D fits to produce natural stone coatings and glossy latex paints.
