BYK Additives & Instruments is one of the world’s leading suppliers in the field of additives and measuring instruments. The coatings, inks and plastics industries are among the main consumers of BYK additives. Yet with exploration technology oil/gas, the manufacture of care products, the production of adhesives and sealants, and construction chemistry, too, BYK additives improve the product characteristics and production processes. As a globally operating specialty chemicals company, BYK has production sites in Wesel, Kempen, Moosburg, Schkopau and Geretsried (Germany), Deventer and Denekamp (Netherlands), Widnes (UK), Wallingford, Chester, Gonzales, Louisville (USA) and Tongling (China).

Our Offer for RTM:

In RTM, resin infusion and other composite manufacturing technologies BYK´s surface additives have a strong positive influence, by enabling fast and complete wetting of fibers and fabric by the matrix resin. Composite materials made using  fiber wetting additives were more homogeneously impregnated and had less pin holes fewer dry spots and a reduced porosity. This is particularly evident in systems with high fiber volume contents.
One example of this product family is BYK-P9920, a highly effective dynamic wetting agent for Epoxy systems. Beyond that, BYK´s range of fiber-matrix coupling agents can also be used in RTM and related processes to optimize the mechanical properties of composites based on glass fibers.

Various Additives to improve processing and properties of RTM materials, e.g.

• Fiber Wetting Agents to improve wetting of fibers and fabrics to give composites with reduced porosity less pinholes and fewer dry spots.
• Fiber-Matrix Coupling Agents to covalently couple glass fibers to thermoset matrix resins (Epoxy, VE, UP) for improved mechanical properties
• Polymer Processing Additives with excellent resin compatibility for better mold release without the common drawbacks of most traditional mold release agents

Development partners to further prove and demonstrate the effect of Additives in High-Speed RTM.
