Application
ADK 4-NN is a flexible, heat resistant biased splicing tape for use on abrasive belt butt splices with flexible X and J weight cloth including non-woven surface conditioning materials. ADK 4-NN is also recommended for fine and medium grit applications that require either good conformability such as pump sleeves and draw sanders or resistance to thermal breakdown which can occur on stroke and edge sanders. ADK 4-NN can be used with glue bond, resin/glue, and full resin coated abrasives for narrow and wide belts.

All Adirondack woven products have been engineered to supply maximum strength in the belt direction without the additional thickness of traditional square weave fabrics. These thin oriented fabrics are also specially weave set to stabilize the tape for easier handling and processing.

Processing
Woven ADK tapes are advantageously used in a two-way adhesive application using contact bonding under pressure with heat activation. The following are suggested parameters which have been successfully employed in joining endless abrasive belts:

Adhesive Type:Linear Polyester Polyurethane
Adhesive Application to Tape:1.5-2.0 mils (37.5-50 microns)
Adhesive Application to Backing:3-12 oz/yd2 (100-400 gm/m2)
Drying Time:10-30 minutes at room temperature depending on the amount of curing agent and relative humidity.
Press Cycle:
  Time:10-20 seconds
  Temperature:72-150F (23-65C)
  Pressure:2000 PSI (140 kg/cm2)
Curing:
  Temperature:Room Temperature
  Time:Full cure will develop between 48 and 72 hours.

Storage
ADK 4-NN is stable for at least 1 year when stored under cool, dry conditions (about 72F/23C). It must be protected from exposure to humidity and direct sunlight.
