Lanxess’ new blocked, one component urethane systems for large or complex elastomeric parts
Lanxess announced new blocked products for cast elastomers. Marketed under the brand name Adiprene K the blocked systems are based on LANXESS’s leading Low Free ( LF) isocyanate technology. They offer three key benefits: Improved industrial hygiene, controlled curing and excellent performance for broader range of applications.
Adiprene K blocked systems have inherently good industrial hygiene, due to the incorporation of low hazard ingredients and the blocking of already low levels of residual isocyanate. As a one-component system, workers do not have to handle a separate curative, improving productivity and worker safety.
Adiprene K blocked systems are available as fully-formulated reactive systems. Curing of these prepolymers is triggered at a precisely defined temperature resulting in a controlled cure. “With these systems, we are targeting large and complex parts and manual processing, which is used for very low volume production,” says Eckert. Potential applications include the impregnation of fabric belts, the coating of industrial rollers, and extremely large parts for the industrial, mining and oil and gas industries. These blocked systems also extend the use of urethane prepolymers into rotational molding and liquid injection molding applications.
