About us

RD Specialties began manufacturing quality coating rods for use on carbon paper and applying hot melt wax coatings. Today our metering rods are used to make window film, tape, release paper, photovoltaic films, wall coverings, specialty papers and many others.

wire wound

Standard lab rods are 16 inches long and available in 3 diameters. They are the ideal size for handheld drawdowns. Type 300 series stainless steel throughout provides corrosion and wear resistance. Most wire sizes are in stock and ready to ship. Click on the core diameter below to order wire wound lab rods now.

gapped rods

For higher viscosity coatings, gapped rods reduce clogging and eliminate lines. By winding a smaller wire with spacing (see image) the cavity created is wide and shallow allowing heavy coatings to flow better. A smaller wire creates a smaller interruption in the coating flow enabling the coating to wet out more completely. While a gapped rod is less durable than a double wound rod, it is also less expensive.

double wound

For higher viscosity coatings, double wound rods reduce clogging and eliminate lines. By winding a smaller wire on top of a larger one (see image) the cavity created is wide and shallow allowing heavy coatings to flow better. A smaller top wire creates a smaller interruption in the coating flow enabling the coating to wet out more completely. While a double wound rod is more expensive than a gapped rod, it is also more durable.
