Mona™ AT-1200

• Acid Stable
• Detergent
• High Foaming Agent
• Rheology Modifier

Mona™ AT-1200 is a concentrated, biodegradable liquid surfactant that delivers dramatic viscosity building properties to acid cleaning formulations. It offers rapid solubilisation with a wide range of viscosities possible for HCI, H2SO4, HNO3 and H3PO4/HCI mixtures. In addition, it offers corrosion inhibition and provides foaming and detergency enhancement to acid cleaners.

Mona™ AT-1200 is ideally suited for use in viscous acid cleaning formulations such as metal cleaners, rust removers, dairy and brewery cleaners, acid bowl cleaners and shower cubicle cleaners.

• Range of high viscosities obtainable
• Corrosion inhibition
• Ease of dilution
• Foaming and detergency boost
• Surface tension reduction
• Long-term stability with a variety of acids
• Multifunctional acid thickener
• Organic and inorganic acids
• Can replace other surfactants and solubilisers
• Protects metal surfaces

Viscosity Building

Mona™ AT-1200 effectively thickens HCI, H2SO4, HNO3 and H3PO4/HCI mixtures.

A wide range of viscosities can be achieved by varying the type of acid, the concentration of acid, or the concentration of Mona AT-1200, as illustrated for the case of HCI and H2SO4 in the following graphs.

In figure 3, shown below, the broad range of viscosity obtainable in 10% hydrochloric acid using Mona™ AT-1200 is illustrated:

Foaming

Mona™ AT-1200 is an effective foaming agent when used with organic acids (glycolic and citric) and inorganic acid such as HCl as shown in the graph below, all samples gave a high level of stable foam:

Corrosion Inhibition

Mona™ AT-1200 effectively inhibits the corrosive attack by acids on metal. The following table shows the reduction in weight loss of various metals when Mona™ AT-1200 is incorporated into hydrochloric and sulphuric acid systems:
