VacuSpray®

The ability to fully automate composite lay-up processes has taken a giant leap forward with the introduction of VacuSpray®. This patent-pending spray-on vacuum bag system was developed to satisfy the overwhelming need of the composite manufacturing industry to reinvent the time consuming and failure-prone conventional vacuum bagging process.

VacuSpray® has proven to minimize, if not eliminate, the need for bleeder breather and FEP layers.  In most cases a narrow perimeter of bleeder breather circumnavigating the part leading to the vacuum ports is all that is required.  FEP is rendered unnecessary since our VacuSpray® bag can be mold released directly.

VacuSpray® SPRAY-ON VACUUM BAGS and CAULS

The VacuSpray® system’s vacuum bags and cauls consist of a two-part polymer specifically formulated to maintain elasticity and elongation while enduring autoclave temperatures as high as 380º F. 

The VacuSpray® Bag or Caul is created using a pressurized, heated spray system. The spray compound begins to cure immediately upon contact. 

VacuSpray® MULTIPURPOSE & VERSATILE

The versatile characteristics of the VacuSpray® compounds have proven to be an excellent material for solving other problems associated with the composite manufacturing process.  VacuSpray® can be used to build a semi rigid caul, used as a durable cover to protect finished parts during transport, even to preserve the working surface of tooling during long term storage.
