Multitec® sprayable polyurethane systems have proven their value in full-featured, high productivity and environmental compatibility The Multitec® polyurethane spray system developed by Leverkusen – Bayer MaterialScience is a typical example of economic and ecological development that are not mutually antagonistic but joint development. This liquid system – with or without glass fiber reinforcement – ​​can be sprayed in open or closed molds to create parts with different geometries. This process has proven to be very effective for producing molded articles. Compared to conventional production using manual lamination, the system has a short curing time that varies between 3 and 5 minutes and has a very positive impact on productivity. In addition, the system eliminates styrene and past energy-intensive post-cure processes. Depending on the application under discussion, the manufacturer can perform multiple spray operations in succession, whether or not glass fiber reinforcement is used, to increase the strength or produce a coatable surface.

Many different types of development have long used these advantages. For example, the complex shape molded hood made by Multitec® reinforced ABS has been designed for use on new tractors manufactured by Pronar Sp. z oo (a manufacturer of agricultural machinery in Narew, Poland). Dr. Marc Schütze, an expert in Bayer MaterialScience Polyurethane Spray Systems, said: "This example is a good example of how polyurethane spray systems can also be used in the manufacture of high quality parts for commercial vehicles."
A glass-reinforced Multitec® staple fiber spray system is also used on Neoplan vehicles to produce 130 x 95 cm anti-drilling molded parts. The molded part is light in weight and can reliably protect the upper oil pan to prevent scattered debris and rotating particles.
The Multitec® staple fiber spray system also proves its value in the production of bathtubs. The shape of the bathtub is generally made by thermoforming polymethyl methacrylate (PMMA) or ABS thermoplastic film. To ensure that the molded article has the necessary stability, the back side of the thermoformed film must be reinforced. Until now, it has been mainly done by a manual process of laminating a film using unsaturated polyester and chopped fiber, which is time consuming and energy consuming. “Our polyurethane spray system is ideally suited to replace previous processes. It cures quickly, does not use styrene and adheres very well to film substrates. Currently in addition to the glass fiber reinforced Multitec® system, we are still developing a A new type of foaming system."
Since March 1, 2007, Bayer MaterialScience has consolidated its entire global polyurethane systems business under the BaySystems® main brand. The move will have an impact on existing product brands in this area, including Baydur®, and the global network of polyurethane systems companies. More information about BaySystems® can be found at
