Gun Roving RO99-690

High-performance reinforcement designed for filament winding and pultrusion with phenolic resin systems. Applications include sprinkler system piping, ventilation ducting, heat shields, mass-transit interior lining panels and pultruded shapes. Its rovings are single-end (zero catenary) reinforcements. Burst strengths comparable to epoxy pipe can be achieved using 690 with phenolic resins. Its characteristics include low fuzz generation and outstanding compatibility with phenolic resins.
