COMBINED FROTH-POUR SPRAY SYSTEM FOR RESIN FOAMS

摘要

Apparatus for processing an organic resin froth from an airless-type spray gun employing an adapter which has a second mixing chamber coaxial with the spray axis of the gun, together with means for selectively introducing either a pressurized mixture of a physical blowing agent to create a froth from the material issuing from the spray gun or a solvent for cleaning the second mixing chamber at the conclusion of the spraying operation.
