Spray Systems » Elastomeric

The development of an elastomeric spray system which would cure at room temperature was required as a direct result of our client's need for processing in high humid conditions with no effect on polymer cure, appearance or properties. The system resulted in outstanding hydrolytic stability and resistance to microbial attack. The development of one of our systems was pigmented Battleship Gray as a result of our client's requirements for use in coating the decks of mine sweepers. In the process of development, the Long Beach Naval Shipyard conducted evaluations on the material and determined it surpassed all requirements for deck coating materials. The material also exhibited excellent adhesion when spayed over fuel-contaminated surfaces.

Spray systems capable of curing at room temperature were developed to produce pillow tanks to store jet fuel. The larger tanks ranging in size from 50,000 gallons to 500,000 gallons required an elastomeric spray system that would surpass the permeability requirements in both the liquid phase and vapor phase without the addition of a barrier material. With our system, two 50,000 gallon tanks were produced and stored outside in pits for a two-year term with no visible loss of fuel. When empty, the tanks could be moved from place to place as needed.

Non-solvent systems were also developed for the pipe industry to protect the metal from corrosion. These systems were capable of curing at room temperature and contributed to the logivity of the pipe.
