Aliphatic polyisocyanate "N-3200" is available from Bayer Corporation.
Note:
Purge Component B with dry nitrogen before sealing container.
Manufacturing Note - Disperse the pigment and thixotrope used in Component
A with a high speed dispersion mixer to a North Standard 5 on a Hegman
gauge, using as much of the resin and solvent blend as required for a good
working viscosity. To prevent deformation of the PTFE pigment particles,
add the chosen Poly(tetrafluoroethylene) to the dispersed material
following the grind operation, under moderate agitation to separate the
particles using the remaining resin and solvent. Agitate until complete
separation of the PTFE has been accomplished. Add any remaining resin and
solvent to completion.
Availability Note - Contact 21st Century Coatings, Inc., Chevy Chase, MD,
