409 Microsphere blend is a low density filler based on hollow glass beads. It is used for filling and shaping fibreglass.
Mixed at a ratio of 10% to 25% by weight with WEST SYSTEM® epoxy, it becomes a smooth paste for filling and repairing fairings with fibreglass. After curing, the mixture is easy to sand.
The 409 filled epoxy mixture is white and can be easily masked with paint or polyester gelcoat. If used below the waterline, it must be protected by additional layers of epoxy.
