Product Overview
Abstract Water-borne coatings and resins have gone through many stages of evolution. Despite steady progress, there is still need for improvements. Recent innovations in the area of polymer colloids and hybrid materials offer new opportunities to develop novel water borne coatings for all most all Industries like packaging, Advertising Printing etc.By choosing the appropriate technology, it is possible to design SBR ,Acrylic , Styrene Acrylate binders with improved barrier properties, low water uptake, and improved enviromental properties. Different methodologies will be discussed including: designed particle morphology, engineering of the water phase composition, and the use of hybrid binders. Also, a new technology exceeding basic barrier function will be presented. IntroductionThe more stringent environmental standards and new technology advances are pushing waterborne coatings for many applications as mentioned above. Currently, most of the R&D effort is focused on reducing the volatile organic content (VOC) content in architectural and industrial coatings. Because the film formation in polymer dispersions is greatly assisted by the use of organic solvents, The pursuit of low VOC formulations can be detrimental to film formation and, therefore, result in poor barrier properties. As a result of the substantial effort in the field, many new waterborne coating technologies have been launched (high performance acrylics, SBR Latices, Styrene Acrylates , epoxy esters, alkyds, zinc rich epoxies, fluoropolymers, polysiloxanes etc).Despite the fact that waterborne systems hold still a relatively low share of the total market for specialty coatings, the average growth rate (AGR) for waterborne coating technology is larger than the AGR for conventional solvent-borne coatings. Other benefits of waterborne coatings are the reduction of worker exposure to organic solvents and of fire hazards in confined areas. Water-based Acrylic or SBR Latices are not new in the market and they have gone through different developments in the last 20 years with the aim of replacing solvent-based systems. The first waterborne systems appeared in the market on the 1960s and were based on formulations containing simple acrylic copolymers with red lead or zinc chromate
