Slow evaporation

Webba b s t r a c t A new semi-organic nonlinear optical crystal of Bisthiourea Ammonium Chloride (BTAC) has been grown by slow evaporation technique. The crystal system and lattice parameters were determined from X-ray diffraction. Fourier Transform Infrared (FTIR) studies confirm the various functional groups present in the grown crystal. WebbIt is a slow evaporating solvent that partitions primarily into the polymer phase of a waterborne coating and reduces Minimum Filming Temperature. It can be used with associative thickeners to enhance application properties such as brushability or roll application in high performance coatings.
