PANGEL S1500 is specially recommended for salt and electrolyte rich systems.

Properties

PANGEL S1500 is a thixotropic additive developed to be used in water-based compositions where electrolytes are present. PANGEL S1500 imparts excellent thixotropic and pseudoplastic properties to the systems it is incorporated to improving stability and spreading properties:

• At rest, it provides the system with a high consistency what produces a suspending effect and a great resistance to settling, avoiding sedimentation. Also sagging and film thickness are highly improved due to this effect.
• Under a shear stress, PANGEL S1500 forces the viscosity to promptly fall down, easing manual and mechanical application and leveling

PANGEL S1500 controls system flow and consistency, ensuring optimal distribution of pigments, fillers and other components. PANGEL S1500 is electrolyte-activated, therefore suspensions made with PANGEL S1500 are specially stable even at high electrolyte concentration. Its rheological behaviour is stable in a broad pH range and at high temperatures. PANGEL S1500 keeps a high absorption capacity and a high degree of interaction with polymers.

Fields of application

• Suspending agent for liquid additives.
• Asphalt emulsions.

PANGEL OM8 is a rheological additive for low to medium polarity systems based upon highly purified bentonite clay. PANGEL OM8 is particularly recommended for systems based on resins such as polyurethanes, acrylics, polyesters, epoxy esters and alkyds.

Properties

PANGEL OM8 is an organobentonite recommended for providing the following properties in intermediate polarity systems:

• Thixotropic and pseudoplastic effects.
• Sag control.
• Excellent levelling.
• Prevents pigment from long-term storage settling.

Fields of application

Use of PANGEL OM8 as a rheological additive is recommended in the following applications:

• Anti-corrosive paints.
• Polyester coatings.
• Primers.
• Industrial finishes.
• Road marking paints.
• Bituminous undercoats.
• Varnishes.
• Inks.
