THICKENER DP-225
Thickener DP-225 is a synthetic thickener containing 2-Acrylamido-2-methyl-propane sulfonic acid sodium salt (AMPS) copolymers dispersed in a paraffin solvent. It is developed for water-based products and polar organic solvents such as ethylene glycol, propylene glycol, and glycerol. This product provides remarkable thickening power between pH 2.0 and pH 12.0, very good mechanical stability and electrolyte resistance. It is especially suitable for systems which polyacrylic acid thickeners do not meet application requirements. 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
- Good thickener for polar solvents
- Excellent workability
- Effective over a wide pH range

Method of Use and Examples
Water or solvent is added to the pre-weighed DP-225 with gentle agitation to prepare a thickener stock. The results of two examples are shown in the following table:
