Fiberglass Material Specification Test Support
Abstract
Battelle has conducted a preliminary investigation for the U.S. Coast Guard to establish an information baseline into possible causes for the blistering of gel coat laminates on boats. It appears to be generally agreed that osmosis (diffusion) is the predominant mechanism for the onset of blister formation, but little agreement is found beyond that. The suspected causes of osmosis are reported to be caused by either physical or chemical debonding between the laminates or between the gel coat and the laminate. In physical debonding, water permeates through the gel coat into an interface. At some point, an osmotic gradient is set up and more water is pulled into the area which will eventually form a blister.
