An inline rotor/stator mixer capable of sub-surface powder injection. The liquid stream (blue) enters the mixer and encounters the solids (yellow) right in the high shear zone, where everything is subjected to intense hydraulic shear. The resulting dispersion (green) is expelled centrifugally through the stator openings at high velocity. Alternative mixing strategies Figure 2. Change-can dual-shaft mixers with discharge systems are widely used for processing glue stick hot melts, pressure-sensitive adhesives, RTV silicon compounds and many other formulations under 500,000 cP. The use of a discharge system eliminates hours of scraping heavy or sticky materials from a mix vessel. With push-button simplicity, the system can automatically discharge several hundred gallons of product in minutes. Alternative mixing strategies Figure 3. 40-gal planetary disperser on a raised base. After the mixing cycle, the vessel is rolled over to the discharge station. A precisely machined platen is lowered hydraulically into the vessel, forcing the finished product out of the bottom valve. The raised base allows for product to be discharged directly into 5-gal pails positioned underneath the vessel. Alternative mixing strategies Formulating pressure-sensitive adhesives (PSAs) presents a number of complex challenges. The adhesive must flow and set without activation from anything more than the pressure of a hand, remain permanently tacky, and exhibit a strong bond—often to a variety of substrates, such as wood, glass, or metal—for as long as the application requires or until the end user decides to remove it.

I am familiar with typical polyurethane raw materials, but have recently become aware of polyaspartic coatings. Could you provide an overview of this technology?

Volume growth is forecast at a 5% annual rate, with coatings, adhesives and sealants matching the overall growth, but inks trailing at only 2% per year.
