Managing condensation with fluid control film apparatus

A condensation management apparatus comprises a microstructured film arranged to condense water vapor on an underside of a substantially horizontal surface. The film comprises channels disposed at least on a first major surface and configured to support capillary movement of condensate. The channels have a channel axis substantially parallel with a longitudinal axis of the film. A capillary siphon structure of the film comprises a fold in the film, a condensate collection region proximate the fold, and a siphon region between the fold and a condensate release location of the film. At least a portion of a second major surface is attached to the underside of the substantially horizontal surface such that longitudinal openings of the channels of the condensate collection region are oriented towards a direction of gravity and the condensate release location is positioned lower along the direction of gravity than the condensate collection region.

Wax-organic extender emulsion and method for manufacture thereof

A wax-extender emulsion including a plurality of wax-extender complex particles suspended in water is described. A wax-extender complex includes a wax component, an organic extender component and a surfactant that stabilizes the wax component and the organic extender component collectively to form the wax-extender complex. The wax-extender emulsion comprises from 2 wt % to 30 wt % organic extender. During manufacturing, the organic extender and wax component are emulsified and homogenized together to produce the wax-extender emulsion. The wax-extender emulsion can be co-applied as a mixture with adhesive resin during wood-based composite manufacturing.
