Influence of Polyurethane Resin on Ink Performance - Pubinderchem.com
Polyurethane resin is a high-performance polymer material with good chemical stability, wear resistance, and flexibility. It has been widely used in coatings, adhesives, and sealants, among other fields. In recent years, with the increasing demand for environmental protection, the application of polyurethane resin in the ink field has also attracted more attention. This article will analyze the influence of polyurethane resin on the performance of ink from a professional chemical perspective. 1. Influence of Polyurethane Resin on the Viscosity of Ink Viscosity is an important factor affecting the printing performance of ink. Polyurethane resin has good thickening effect, which can effectively improve the viscosity of ink. By adjusting the molecular weight and structure of polyurethane resin, viscosity within a certain range can be controlled to meet different printing needs. In addition, polyurethane resin can also improve the flowability and drying speed of ink, thereby im...
