Presstige™ biosolvents
Presstige biosolvents comprise a family of proprietary products used for felt conditioning, general cleaning and roll treatments. The products, which are based on natural agri-based oils (i.e., oil produced from agricultural produce), are extremely effective at removing pitch and stickies deposits from paper machine clothing and surfaces. The properties of the biosolvents mirror those of methylene chloride, an extremely effective solvent. However, unlike conventional solvents, Presstige biosolvents contain low VOCs, feature excellent HMIS ratings, have high flash points and emit mild odors.
Laboratory testing and commercial applications confirm that Presstige biosolvents are more effective at removing pitch and stickies deposits than conventional solvents. And because the biosolvent can be safely applied to hot surfaces, such as felts, or mixed with hot water, which improves reaction kinetics, they allow for a more complete cleaning.
