Systems for producing, applying and evaluating coating compositions are disclosed. An automatic color matching system includes an automatic coating component dispenser, a container, a mixer for mixing the components of the coating composition and a solvent, an automatic pressurization station to apply pressure to the mixed coating composition, and a robotic arm to transport the container to and from the mixer. A coating composition dispensing system includes a computer to provide a target formulation for a coating composition, an automated component dispenser containing the components of the coating composition, a container positionable adjacent to the component dispenser to receive the components of the coating composition, and an automated component sensor to measure the amounts of each of the components dispensed into the container. The computer is programmed to store data corresponding to the measured amounts of each of the components, and amounts of components contained in the coating compositions may be monitored, along with processing parameters when the coating compositions are applied to various substrates. The characteristics of a produced sample coating may be compared with the characteristics of a target or reference coating to determine if they are sufficiently matched.

Systems for automated production, application and evaluation of coating compositions

Systems and methods for producing, applying and evaluating coating compositions are disclosed. The amounts of components contained in the coating compositions may be monitored, along with processing parameters when the coating compositions are applied to various substrates. In certain embodiments, the characteristics of a produced sample coating are compared with the characteristics of a target or reference coating to determine if they are sufficiently matched.

System and method for automated production, application and evaluation of coating compositions

A photovoltaic module can be produced by suspending a photovoltaic cell with a front side of the photovoltaic cell facing upward, positioning a backsheet and a first encapsulant layer underneath the suspended photovoltaic cell, lowering the suspended photovoltaic cell into contact with the first encapsulant layer wherein a back side of the photovoltaic cell contacts the first encapsulant layer, applying a second encapsulant layer over at least the front side of the photovoltaic cell, positioning a front transparency onto the second encapsulant layer, and curing the first encapsulant layer and the second encapsulant layer.

Process and system for producing photovoltaic modules

A panel carrier system and method for coating panels with the carrier system are disclosed. The carrier comprises a base and protective cover with an enclosure that protects the base when coating compositions are applied to the panels. The carrier system and coated panels may be transported to a curing location, followed by removal and evaluation of the coated panels.

Carrier systems for coating panels

Systems for delivering coating compositions are disclosed. The system may include a support base for supporting a container of a coating composition and a pressure canister movable in relation to the support base from an open position to a closed position in which the pressure canister surrounds the coating composition container and forms a seal with the support base. The system may include a pressure canister that is movable from a delivery position in which the canister is pressurized to a cleaning position in which the canister may be cleaned by a cleaning fixture. The pressure canisters are useful in automated systems for delivering various types of coating formulations.

Pressure canisters for automated delivery of coating compositions

The present invention provides an at least partially coated fiber strand comprising a plurality of glass fibers having a coating composition on at least a portion of at least one of the glass fibers, the coating composition comprising at least one coating comprising greater than 20 weight percent on a total solids basis of a plurality of particles selected from inorganic particles, organic hollow particles, composite particles, and mixtures of any of the foregoing, wherein the plurality of particles have a Mohs' hardness value which does not exceed the Mohs' hardness value of the glass fibers.
