Description
Valspar Pigment Dispersions are made with the highest quality
pigment in a vehicle that is excellent for use with polyesters and
urethanes, and is also compatible in many cases with vinyls and
epoxies. The pigment dispersions are low in viscosity and smooth,
blending evenly when stirred into liquid resins. Opacity is obtained
at a pigment level of 3% to 5% depending on part thickness.
Works
well in continuous casting equipment.

Application
For
polyester resins: Mix pigment dispersion into a small amount of
resin before adding to the main portion of resin - prior to adding
the catalyst. The resins can be colored and stored for use at a
later date, when only the catalyst needs to be added.
For
epoxies: Make compatibility tests to assess the pigment's suitability
due to differences in types of resins and hardeners. Limit pigment
level to 2%.
For
vinyls and urethanes: Test the desired color concentration before
use. In a urethane system, disperse the pigment in the resin phase.
