SynFoam syntactic Foam Logo

SynFoam SG is a unique, cost effective castable syntactic foam that provides low density and moderate strength. It is suitable for numerous marine and aerospace applications where machining of parts is either impractical or too expensive. SynFoam SG is also ideal ideal for field repair due to its room temperature cure which also eliminates CTE problems that will arise with elevated temperature cures. SynFoam SG exhibits low shrinkage and is resistant to water, oils, and fuels. The castable nature of the syntactic eliminates the cost and waste associated with machining. .

SynFoam SG is available as 1, 2, and 5 gallon kits. Each kit contains an A and B side that must be mixed together prior to casting. Cure is achieved within 24 hours and full properties will be realized after 7 days at room temperature. Densities can be customized to the user's specifications. Please consult the appropriate instructions for limitations of depth of cure.

If you have a specific mold for use with SynFoam SG we also provide final casting and fabrication services. Services include casting and finishing with a quality marine based paint.
