Intake manifold is a part of an engine that supplies fuel/air mixture to the cylinder heads. Recently, silicone FIPG has been used for the two part design of the intake manifold. It is known that a small, but significant, amount of gasoline fuel can penetrate through silicone FIPG layer due to the flexible nature of the siloxane backbone. Since gasoline permeation is becoming more important because of more severe regulations, it is found that a new polyacrylate based FIPG dramatically reduces the gasoline fuel permeation.
This study compares this new technology, polyacrylate FIPG sealant with silicone FIPG sealant used today for vehicle powertrain gasketing applications. Adhesion investigation on both aluminum and magnesium alloys, and oil resistance are also discussed in this study.
