THICKENER AT-76
Thickener AT-76 is a synthetic acrylic copolymer dispersed in a paraffin solvent. It is developed for the thickening of water-based products, especially for the textile printing industry. The product can be used directly and does not require the addition of ammonia or other alkali to the system.
This product has the following benefits:
- Extremely easy to use and highly efficient
- High electrolyte resistance and flush resistance
- Superior definition and color yield
- Excellent workability
- Effective over a wide pH range
Typical Physical Properties
- Appearance: Creamy liquid
- pH: 8.0 ± 1.0 (light ammonia odor)
- Solids: 31.0 ± 1.0%
- Specific gravity: 1.20
- Viscosity: 20,000 ± 5,000 cps (Brookfield, RVT, #6, 5 rpm)
Method of Use and Example
Water is added to the pre-weighed AT-76 with gentle agitation to prepare a thickener stock. Binder, pigment, and other ingredients of the printing paste formulation are then added to the thickener stock to make the final printing paste. For example, a printing paste with the composition below has a viscosity of 20,000 - 25,000 cps (Brookfield, RVT, #6, 5 rpm) and gives excellent print definition and color yield.
*This example is for reference only. The formulation should be adjusted to the product requirement. The viscosity may vary due to water quality or other additives.
