Webb14 jan. 2010 · Historically, vacuum infusion of thick laminates has been avoided because of the likelihood of uncontrolled or “runaway” exotherm. But this 5.375 inches/135 mm thick fiberglass/vinyl ester hatch cover for a flue gas desulfurization installation was successfully produced by Kenway Corp. (Augusta, Maine) using a resin modified with new initiator … WebbVacuum Infusion. Vacuum infusion, also called resin infusion, is a fabrication technique that uses vacuum pressure to drive resin into a laminate. Dry materials are laid into the mold and the vacuum pressure is applied before resin is introduced. Once a complete vacuum is achieved, resin is forced into the laminate via vacuum tubing.

WebbResins such as the #77 Molding Resin and #90 Isophthalic Resin provide a viscosity of about 475 centipoise, allowing it to infuse quite readily during your vacuum infusion project. System 2000 Epoxy System 2000 offers a viscosity of 900-975 centipoise (depending on hardener choices) meaning it will infuse slower.
