  • No information on the dusting potential of the additive was made available. The analysis (by sieving) of one batch of the additive8 showed that 100% of the additive had particles smaller than 420 μm.

  • In the construction sector, HPMC plays a crucial role as a water retention agent and cement additive. It enhances the workability of concrete, improving its flow properties while reducing water demand. This not only increases the durability of structures but also aids in energy efficiency during production.
  • 2. Degree of Substitution As mentioned earlier, the degree of substitution (DS) refers to the number of hydroxyl groups on the cellulose molecule that have been substituted with hydroxypropyl groups. HPMC with a higher DS tends to be more hydrophilic and has a greater thickening effect.
  • Hydroxypropyl methylcellulose, commonly known as HPMC, is a cellulose-based polymer that is commonly used in wall putty formulations due to its excellent thickening, water retention, and adhesion properties. These properties make it an ideal additive for wall putty as it helps to improve workability, consistency, and durability of the final product.
  • Paints and Coatings:

  • Overall, HPMC is a versatile and multi-functional ingredient that is widely used in various industries. Its unique properties make it an essential component in the formulation of a wide range of products. Whether it is used as a thickening agent, film-forming agent, emulsifier, or stabilizer, HPMC provides numerous benefits and enhances the quality of the final product.
  • HEC possesses a high degree of molecular flexibility, which allows it to form stable films and hydrogels. Its hydrophilic nature enables HEC to retain a high level of moisture, making it suitable for use in moisturizing creams and lotions. Additionally, HEC exhibits good thermal stability, allowing it to maintain its properties over a wide range of temperatures. Furthermore, HEC is non-ionic, which means it does not ionize in aqueous solutions, making it compatible with a variety of other compounds.
  • Textile manufacturers utilize VAE powder to create eco-friendly coatings and finishes, which not only improve the fabric's durability but also offer water-repellent and flame-retardant properties
