Standard DMDA Organoclay — Substitution & Grade Selection Guide

What Is Standard DMDA Organoclay?

Standard DMDA organoclay is the baseline chemistry for the most widely used organoclay rheology modifiers in industrial coatings and drilling fluids. It is produced by reacting high-purity sodium montmorillonite with dimethyl dioctadecyl ammonium (DMDA) chloride via wet-process ion-exchange, then drying and milling to specification.

Drop-In Substitution from Other Standard Grades

CP-34 uses the same DMDA-modified wet-process chemistry as all equivalent standard organoclay grades. Formulators switching from any standard DMDA organoclay can substitute CP-34 at the same usage level with no formulation changes required.

1. Request a free CP-34 sample (200 g–2 kg available by courier)
2. Run a side-by-side dispersion test in your current formulation at the same treat rate
3. Measure thixotropic index and anti-settling performance against your current result
4. We provide TDS, SDS, and COA for full qualification documentation

Why Source CP-34 Direct from Manufacturer?

• 20–40% cost reduction vs. Western-distributed equivalents — no distributor margins
