November 22, 2006—Hercules Incorporated has announced that the Aqualon business unit is introducing Culminal S cellulose ethers as a result of technological developments based on unique methylcellulose chemistry. This chemistry offers new superior performance to the construction market, says the company.
Compared to other cellulose ethers, the Culminal S line of products, says the company, offer faster cement setting due to extremely low retardation effect; improved strength development; smooth dispersion in gypsum machine plaster reducing lumps and improving workability; and high mortar stability giving constant properties over the entire working life.
Culminal S cellulose ethers for various grades of tile cement and gypsum machine plaster are available now, or will be commercialized by the end of the year. New Culminal S products tailored to specific end uses and customer requirements are planned as additions to this product line.
