Saturants
Saturating or “weeping” resins are unique in the way that they are used to wick into small voids and porous structures to consolidate and add strength when cured. We approach saturant applications much like in our other segments, working to understand the forces affecting the application, the desired cured characteristics, as well as the desired ‘working conditions’ when applying the resin.
Because these materials become an integrated part of the substrate to which they are applied, we assess material compatibility to ensure optimal bonding once cured. From high-temperature VPI insulating resins to less-caustic, occupationally-friendly resins used in repair operations, it is critical for saturants to be well-matched with the substrates to which they are applied and the operating conditions they will experience in service.
