High efficiency surfactant and versatile wetting agent.
DeCAL 2170 is a formulated aqueous/propylene glycol solution of sodium dioctyl sulphosuccinate.
1.Typical properties:
- Appearance Colourless liquid
- Active content 66%
- Solid content 70%
- Density 1.01g/cm³
2. Applications:
Solubility of DeCAL 2170 in water based formulations depends on type of electrolyte and concentration, e.g. in the presence of 1% sodium chloride a turbid solution is formed. The active substance of DeCAL 2170 is hydrolysed by acids and alkalis. The best working range of pH is between 6-9. The products of hydrolysis are water soluble. Since any component present in a formulation can have significant impact on the overall latex properties, compatibility and dosage level should always be checked in the actual formulation.
Typical uses of DeCAL 2170 include:
- Pigment Dispersion - Self-emulsifying pigment pastes can be formulated comprising of only the pigment and DeCAL 2170
- Water based coatings - DeCAL 2170 may be post-added to a coating formulation to assist the wetting of substrates with low surface tension, e.g. plastics and metals. The optimal concentration range for DeCAL 2170 in this application must be derived from a series of experiments in the actual formulation in order to achieve maximum wetting with low foaming.
- Water based wax formulations such as car polishes can be stabilized against phase separation by addition of DeCAL 2170.
3.Recommended concentration of DeCAL 2170:
- Pigment Dispersion - up to 5% Based on pigment weight.
- Water based coatings: 0.05 - 0.3% based on total formulation.
- Water based wax formulations - up to 5% based on wax weight
