Foster® Vapor-Out™ Coating 30-33 is a water-based vapor retarder coating designed for insulation, suitable for interior and exterior applications. It is particularly useful for low-temperature and some dual-temperature scenarios, including chilled water and refrigerated pipelines, HVAC ducts, and low-temperature equipment. This coating dries quickly, creating a resilient, flexible, and dry film that safeguards insulated surfaces and hinders vapor flow through the insulation system.
