Abstract: An apparatus for mixing and spraying a catalyst with a resin onto a surface. The resin and catalyst are internally mixed within a disposable mixing tube. After the spraying is completed, the catalyzed resin is allowed to harden within the tube and the tube is thereafter disposed of. Because the catalyst and resin are not mixed within any reusable portions of the spraying apparatus, the need for rinsing with acetone or similar hazardous solvents is eliminated.
Abstract: An apparatus for monitoring and spraying a catalyst with a resin onto a surface. A pressure gauge is attached to the manifold of a spray gun to monitor the pressure of catalyst within the manifold. The pressure gauge warns of and diagnoses problems with the apparatus ranging from a damaged pump to a plug in the manifold.
Abstract: An apparatus for mixing and spraying a catalyst with a resin onto a surface. The resin and catalyst are delivered to a mixer having no O-rings which could become clogged with catalyzed resin and destroy the gun. The manifold is connected to a mixer which is connected to an air supply. The spray gun eliminates the need for any check valves within the manifold.
Abstract: An apparatus for mixing and spraying a catalyst with a resin onto a surface. The resin and catalyst are internally mixed in confluence with pressurized air. The sprayer is provided with a specially designed check valve to prevent resin and catalyst from entering the pressurized supply line. The construction of the check valve prevents it from clogging or becoming stuck shut during operation.
Abstract: An apparatus for mixing and spraying a catalyst with a resin onto a surface. The apparatus is provided with a restricted orifice union on the resin line running into the manifold. The union traps large plugs of resin and prevents them from entering and clogging the manifold. The union is designed so that plugs of resin may be easily removed from the resin line with only a minimum of down time.
