Sustainability & Environmental Considerations
Product Examples & Applications
Whether it’s classic cavity wax, thin-film cavity sealing for the narrowest gaps, or transparent systems for visual inspection: The PFINDER portfolio offers the right solution for virtually any cavity preservation application. Variants with different flow properties, viscosities, and drying speeds allow for optimal adaptation to your manufacturing processes—from OEM series production to post-preservation in the after-sales sector.
For complex body structures, high-crawling cavity sealants are available that penetrate even overlapping seams and hard-to-reach areas. In addition, we offer cavity waxes with increased temperature resistance e.g., for commercial vehicles, buses, or export vehicles with particularly high corrosion exposure. Together with you, we define the right combination of product, application technology, and process window.
In conjunction with our technical support, you can ensure cost-effective, efficient, and reliable results in the field of cavity sealing.
