    Abstract: The present disclosure relates generally to photocurable compositions and methods for continuously forming a three-dimensional body from these compositions. More particularly, the present disclosure relates to photocurable compositions comprising a mixture of polysiloxanes capable of being dually cured, i.e., first by UV radiation followed by thermal treatment, or being cured by UV radiation. In one aspect, the disclosure provides a photocurable composition, including: a first polysiloxane comprising at least two acrylate or methacrylate groups per molecule; a second polysiloxane containing at least one (e.g., at least two) Si—H group per molecule; a third polysiloxane containing at least one (e.g., at least two) reactive aliphatic ethylene group per molecule; a free radical photoinitiator in an amount of about 0.01 to about 10 weight % based on the total weight of (meth)acrylate-containing polysiloxane in the composition; and a hydrosilylation catalyst in an amount of about 0.001 to about 10 weight % hydride-containing polysiloxane and vinyl-containing polysiloxane in the composition.

    Abstract: The present disclosure relates to a multilayered film that may include a first PET substrate, a first anti-microbial coating overlying the first PET substrate, and a first self-wetting adhesive layer underlying the first PET substrate. The first anti-microbial coating may include a silver-based filler component within the acrylate-based component. The first anti-microbial coating may have a MRSA anti-microbial rating of at least about 75%, where the MRSA anti-microbial rating is defined as the percent reduction of methicillin-resistant Staphylococcus aureus (MRSA) activity from an initial inoculation of MRSA on the surface of the anti-microbial layer after 24 hours as measured using ISO22196.

    Abstract: According to a first aspect, a method of designing a radome may include defining a set number N of flight paths FPN, where each flight path FPN is between a first city and a second city, determining a Looking Angle Distribution (Lα-Dist) for each flight path FPN, calculating a Combination Looking Angle Distribution (Combo-Lα-Dist) for the set number N of flight paths FPN, determining a Combination Incidence Angle Distribution (Combo-Iα-Dist) corresponding the Combo-Lα-Dist, and tailoring at least one radome shell structural component of the radome to minimize electromagnetic degradation of electromagnetic waves intersecting the radome at angles within the Combo-Iα-Dist.

    Abstract: Filter capsules for showers and sinks used in surgical settings, clean rooms and other contaminant-sensitive settings having modified outlets for improved splash control. Flat, concave, convex, asymmetric concave and asymmetric convex outlet inserts have pluralities of fluid bores with varying orientations to permit enhanced fluid flow control out of the filter capsules including divergent, convergent and mixed divergent/convergent fluid flows. An inlet with an axis offset at an angle to the longitudinal axis of the filter capsule body permits user control over the fluid flow strike point in a sink or shower stall via rotation of the capsule about the inlet connection point. A recessed outlet improves the prevention of contaminant dispersal by recessing the outlet away from contact points and potential contaminant sources. A filter cartridge top cap includes a downwardly extending extension with a concave bottom end to redirect fluids undesirably entering the filter capsule from the outlet away from the enclosed filter media and out the outlet.
