Composite repair solutions and material supplier Heatcon Inc. (Seattle, Wash., U.S.) is offering Deployable Isolation Repair Technology (DIRT Bag) products, which Heatcon is manufacturing and distributing through an agreement with Cornerstone Research Group (CRG, Miamisburg, Ohio, U.S.)

According to Heatcon, DIRT Bag provides composite repair technicians with an off-the-shelf solution to provide contamination and environmental control during the repair process. During damage removal, the DIRT Bag is said to keep contaminants from entering the surrounding environment and can be used with HEPA vacuum systems. DIRT Bag can also be used during the repair layup or curing process to keep outside contaminants from entering the repair area, and can be used with environmental control units that provide temperature and humidity controlled air to the enclosed area.

It can be set up in minutes and can be customized for each repair or coating removal situation.

  • A self-adhesive seal
