Engineered Syntactic Systems SF-30 Subsea Syntactic Void Filler
Categories: Polymer; Thermoset; Epoxy

Material Notes: SF-30 is a low cost, low density syntactic formulated to serve as a void filler for shallow water subsea applications. The material is provided as a three-part kit that is mixed and poured into any freeflood cavity or void. The mix is allowed to cure at room temperature to form a solid syntactic material that will withstand repeated ocean excursions to depths of 1,500 feet. The easily cast system is provided in three parts; two resin components and a solid filler. The two resin components are mixed together, followed by the glass bubble filler. When the three materials are uniformly mixed, the moderate viscosity combination may be poured into its desired location. Initial cure will occur over a twenty four hour period at ambient temperatures, (50°F - 90 °F), providing a solid, lightweight article which is ready for any secondary operation such as machining, finishing or painting. Full cure will take place after 7 – 10 days. The cured material will provide an average of 34 pounds of buoyancy per cubic foot in seawater.
