Klucel hydroxypropylcellulose is a nonionic water-soluble cellulosic polymer with a versatile combination of properties. it combines organic solvent solubility, thermoplasticity, and surface activity with the thickening and stabilizing properties of other water-soluble cellulose polymers. Klucel is available in a wide range of viscosities with measurements reported at varying concentrations in water Key Attributes: - Klucel is soluble in many polar organic solvents and in water below 38°C, but is insoluble in water above 45°C. - Klucel is highly surfae-active, with low surface and interfacial tensions of solutions. It has a wide range od compatibilities with latexes and with synthetic and natural colloigs. - In films and coatings, Klucel is heat-sealable, extremely flexible without plasticizers, and non-tacky at high humidity. Main Applications are: - Film-former and rheology control for Coatings - Solvent based systems and Hot-melts in Adhesives
