Systems, methods, and compositions for producing liquid repellant materials include a first support configured to support a spool of flexible substrate, a second support configured to support a plurality of compressing rollers configured to apply a force to a segment of the flexible substrate that extends from the roll. The segment is located within a zone between the compressing rollers. The system, in an embodiment, has a plurality of gas directors, wherein each one of the gas directors is configured to direct a stream of gas that flows at least partially around one of the compressing rollers. The streams cause an air pressure reduction in the zone. Also, the system has a precursor supply configured to expose the substrate to a precursor (e.g., a siloxane precursor), resulting in a coated material or protected material.

A system for treating a substrate comprising a treatment module and a substrate plane. The substrate extending along a substrate plane to treat the substrate and wherein a fluid is deliverable via the module to a local region between the module and the substrate plane to treat the substrate with a predetermined treatment.
