WIDOPAN-Universal Primer is used for all subsequent seals made of WIDOPAN-FD and WIDOPUR 1K. Furthermore, this primer is also used before applying WIDOPERL. Then, the application is done “wet in wet” (for further details, please refer to our product information for WIDOPERL).
WIDOPAN-Universal Primer hardens with exposure to air, and is one-component, making it particularly economical to process. The addition of a crosslinking agent ensures rapid curing even at low temperatures. The polyurethane-based primer can be used on almost any surface and provides adequate protection against alkalinity.
Tests should generally be made on curing and adhesion to the substrate.
