Product Usage

Coating solvent: due to its good solubility and moderate volatilization rate, can effectively dissolve a variety of resins, such as alkyd resin, acrylic resin, etc., so that the paint has good leveling and gloss, widely used in the production of paint, paint, help to improve the construction performance and drying speed of paint.

Ink solvent: In the ink industry, it can be used as a solvent to help dissolve pigments and resins in the ink, so that the ink has good fluidity and transferability, and ensure the printing quality, and is often used in the manufacture of offset ink and gravure ink.
