The HPMC capsule itself is made from a wood source, so is often described as natural. Of course the contents of the capsules you buy may or may not be from a natural source, but the shell itself will be.
In the paint and coatings industry, HPMC is employed as a thickener and film-former, enhancing the application properties and the final film's performanceA mortar bonding agent, typically a specialized type of cement, is a blend of fine aggregates, water, and a binder. The binder, usually Portland cement, lime, or a combination of both, is what gives the mortar its binding properties. It is this component that interacts chemically with the surface of the masonry units, creating a robust connection. The role of the bonding agent is not just limited to adhesion; it also enhances the workability, durability, and weather resistance of the mortar. Another significant benefit of redispersible polymer powders is their ability to increase the flexural strength and impact resistance of cementitious composites. When added to concrete or mortar, these powders form a network of microfibers that provide additional support and reinforcement, making the material more resistant to cracking and deformation under stress. This is particularly useful in applications where the structure is subjected to heavy loads or dynamic forces, such as bridges, highways, and industrial floors. The solubility of HEC in cold water is typically slow, often requiring agitation or heating to facilitate dissolution
