"Acrysol" ASE-60/4.4
Water/4.4
The formulation should be made in the indicated order. Before
addition of the diluted "Acrysol" ASE-60, the pH should be measured and
adjusted, if below 7.4. A pH in the range 7.4-8.0 is satisfactory.
following addition of "Acrysol" ASE-60, the pH may again require
adjustment by addition of ammonia to pH 7.4-8.0. The typical formulation
given above has an initial viscosity of about 28,000 cps. and can be
applied by knife coater.
Where dimensional stability alone is required, "Rhoplex" TR-520 can be
pigmented with whiting or clay, dispersed with "Tamol" SN, and the
formulation can be thickened with "Acrysol" ASE-60. Good fabric
stability and a non-tacky hand are obtained with filled formulations of
this type, applied by kiss roll or knife coater.
