Viscosity Improver

Product Details:

Acry Thick KWT-60 Acrylic Thickener KWT-60 is an acid – containing cross-linked Acrylic emulsion copolymer. When the emulsion diluted with water and neutralized with a base, each emulsion particle swells greatly. The emulsion clarifies under these conditions and becomes highly viscous. Thickener KWT-60 being a Poly acrylic thickener gives superior performance than conventional thickener like CMC, HEC. Storage stability of paint with Thickener KWT-60 is much superior that CMC or HEC. Solutions for use are prepared rapidly since neutralization occurs instantaneously with a variety of standard bases. Handling is greatly simplified, compared to that required with powdered natural or synthetic gums, cellulose thickener. It is frequently possible to incorporate Thickener KWT-60 directly into the system to be thickened without pre-neutralization. This avoids handling a viscous thickener solution. Thickener KWT-60 fully neutralizes at a pH 8.0 approximately. Solutions of Thickener KWT-60 effectively suspend pigment, abrasive and other finely divided solids.

Physical Properties:

• Storage: Protect from freezing
• Miscibility : Good in water
• Colloidal charge : Anionic

Applications:

• Thickener KWT-60 is also useful for viscosity adjustment of emulsion and latex compounds of many types. In such applications Thickener KWT-60 is complementary to the action to linear thickners.

Rheological Additive World RHEO 38 Rheological Additive for Solvent Base & Oil Base. World RHEO 38 is modified organoclay, designed especially for use in solvent base and oil base system including intermediates low polarity range organic liquid.

Key Benefits:

• Exerts gelling efficiency over a wide range of intermediate and low polarity.
• Easy dispersing.
• The gel is colourless and of high clarity.
• Produce reproducible thixotropic consistency over a wide temperature range.
• Imparts particle suspension, sag resistance without impairing flow and levelling preventing hard setting of pigment and fillers.
• Exerts strong film reinforcing action in organic binder systems.

How and where to incorporate World RHEO 38:

• World RHEO 38 disperses under high shear and requires a polar activator (30%~40%) for the best efficiency. Heat is not required to obtain a good dispersion
• Addition levels are typically in 0.2%~2.0%
• Polar activator (95% Ethanol or 95% Methanol) is needed.
• Normally addition level of polar of polar activator is recommended to be 30%~40% of World RHEO 38 in weight

Organoclay Thickener Rheological Additive for Solvent Base & Oil Base. World RHEO 3452 is modified organoclay, designed especially for use in solvent base and oil base system. It can be used widely in solvents and oils from low polarity to medium-high polarity.

Typical Properties:


Key Benefit:

• High gelling efficiency.
• Wide application range, it can be applied in all low, middle and high-temperature range.
• Produce reproducible thixotropic consistency over a wide temperature range.
• Imparts particle suspension, preventing hard setting of pigment and fillers.
• Exerts strong film reinforcing action in organic binder systems.

How and where to incorporate WORLD RHEO 3452:

• World RHEO 3452 disperses under high shear and requires a polar activator for the best efficiency. Heat is not required to obtain good dispersion. Addition levels are typically in 0.2%~2.0%. Polar activator (95% Ethanol or 95% methanol) is needed. Normally addition level of polar activator is recommended to be 45%~60% of World RHEO 3452 in weight. If xylene system, addition level of polar activator is about 30%~40% of World RHEO 3452 in weight.

Pre- gel is made as below procedure:

 

• Charge solvent to mill.
• Slowly add World RHEO 3452 (6-10% by weight of total pre-gel) to mill under agitation.
• Mix at high speed for 5 minutes.
• Add polar activator.
• Mix at high speed for 5 minutes.
