Rodding Bonder RD50

Rodding Bonder RD50

Reinforce your peace of mind


Protect your fabrication with reinforcing rods and our fast curing, high strength RD50


Rodding Bonder RD50 is an epoxy based Bonder packaged in a 500ml dual component cartridge designed to embed fiberglass or steel reinforcement rods in countertops. Testing shows that the process can improve load tolerance up to 300% and deflection up to 1600%.

Rodding Bonder RD50 uses a measure-mix-dispense system (cartridge) that combines the strength of an epoxy with the cure speed and consistency of an acrylic. RD50 saves time (15-20 minute cure time), virtually eliminates waste and reduces overall costs.

Rodding Bonder provides excellent bond strength for the various rod options available to fabricators; Steel and Fiberglass rods are both compatible.
