Hydroxypropyl methylcellulose is mainly used in the construction industry-cement mortar and putty powder are the largest application industries, and their demand accounts for 70%; the coating industry-real stone paint, water-based paint, and glue will require a large amount of hydroxypropyl Methylcellulose;
Construction industry applications:
Plastering mortar: also called surface mortar. The addition of hydroxypropyl methylcellulose to the plastering mortar can improve the uniformity, making the plastering mortar easier to coat and improving the anti-sagging ability. Enhance fluidity and pumpability, thereby improving work efficiency. In addition, it can effectively limit the infiltration of air, thereby eliminating micro-cracks in the coating and forming an ideal smooth surface.
Masonry mortar: The addition of hydroxypropyl methylcellulose to the masonry mortar can enhance the adhesion to the surface of the masonry, and enhance the water retention, so that the strength of the mortar can be improved. Improve lubricity and plasticity to improve construction performance, easier to apply, save time, and improve cost-effectiveness.
Self-leveling mortar: Hydroxypropyl methylcellulose added to self-leveling mortar can provide viscosity and can be used as an anti-settling additive. Enhance fluidity and pumpability, thereby improving the efficiency of paving. Control water retention, thereby greatly reducing cracks and shrinkage.
Water-resistant putty: Hydroxypropyl methylcellulose in the water-resistant putty mainly plays a role in water retention, adhesion and lubrication, to avoid cracks and dehydration caused by too fast water loss, and at the same time enhances the adhesion of the putty and reduces the sag phenomenon during construction , The construction is relatively smooth.
Coating industry application:
Water-based paint: The addition of hydroxypropyl methylcellulose to water-based paint can improve water retention and leveling, which can significantly improve product performance, improve coating performance, and reduce environmental pollution.Tags: HPMC, Hydroxypropyl MethylCellulose
