How does HPMC improve coating adhesion?
Hydroxypropyl Methylcellulose (HPMC) is a versatile cellulose ether widely used in coatings, construction, and industrial applications. It significantly enhances the adhesion of coatings through multiple mechanisms, as detailed below: 1. Thickening Effect HPMC acts as a thickening agent, increasing the viscosity of coatings and improving their rheological properties. This thickening effect prevents sagging during application,
