Coatings industry
Special features and benefitsGaramite-1958 is a unique rheology additive with very wide compatibility in a wide range of solvent- based and solvent-free coating systems.
Garamite-1958 has the following product features and benefits:
• Pseudoplastic flow
• Improves sagging resistance
• Improves anti-settling properties
• Supports the alignment of effect pigments
Due to its high bulk density, it is easy to handle and is not sensitive to shear forces.Recommended levels
0.1–2% additive (as supplied) based on the total formulation.
The above recommended levels can be used for orientation. The optimum dosage should be determined by application-related test series.
Incorporation and processing instructions
The additive can be incorporated in various ways. Garamite-1958 is either dispersed directly in the millbase or added as a 10 to 15% paste in solvent to the millbase or letdown. It should be incorporated into the solvent using adequate shear forces. When adding during the grinding process, it should be pre-dispersed in the binder and solvent with moderate shear forces before adding the pigments and fillers. The effect of Garamite-1958 can be increased by adding a booster or small quantities of a polar solvent or water.Powder coatings
Special features and benefits
Garamite-1958 is a rheology additive that can be used to increase melt viscosity in powder coatings. Even at low dosage, the melt viscosity is increased during extrusion and cross-linking reaction. The resulting coating will maintain good flow properties despite its increased viscosity. The combination of different morphological structures in the mineral component results in particularly easy dispersibility with high efficiency. Garamite-1958 is recommended for epoxy-based resin systems. Higher dosages result in a fine texture finish and a reduction in the gloss level. Garamite-1958 can be used to modify the surface structure in finely textured systems. The increased melt viscosity improves edge coverage. This
results in better corrosion resistance.
Recommended use
The additive is recommended for powder coatings based on epoxy, polyester, polyurethane and acrylate resins as well as polyester/epoxy combinations. It is particularly recommended for epoxy-based binders.
Recommended levels
0.5–4% additive (as supplied) based on the total formulation.
The above recommended levels can be used for orientation. The optimum dosage should be determined by application-related test series.
Incorporation and processing instructions
The additive should be mixed with resin, curing agents, pigments and other raw materials in a high-speed mixer and then extruded.Thermosets
Special features and benefits
Garamite-1958 is a solid rheology additive based on a composition of organically modified phyllosilicates. The combination of different morphological structures in the mineral component results in particularly easy dispersibility with high efficiency. Garamite-1958 delivers the following advantages over conventional rheology additives in various resins based on unsaturated polyester, vinyl esters, polyurethanes and epoxy resins:- Allows adjustment of low to higher viscosities and various layer thicknesses
- Prevents filler settling
- Systems with Garamite have very good shear-thinning flow properties
- Higher efficiency or lower application volume, especially in combination with booster additives
- Reduced dust generation in production compared to fumed silica
- Easy to incorporate as extremely low shear forces are required. The processing time can be significantly reduced compared to conventional fumed silica.
- No activation by heat or activators required
- Less storage area due to higher bulk density compared to fumed silica
Recommended levels
0.5–5% additive (as supplied) based on the resin content.
The above recommended levels can be used for orientation. The optimum dosage should be determined by application-related test series.
Incorporation and processing instructions
Garamite-1958 can be incorporated directly into the resin. A premixture in styrene is recommended to achieve full efficacy in UP/VE resins (dosages 0.5–2%). For this purpose, 8 to 12% Garamite-1958 must be incorporated into styrene. At this concentration, the mixture can still be pumped and will still flow and can be later dosed to the resin. The use of deaerators in such resins is advisable to reduce the quantity of air bubbles. Content in UP/VE resins can be reduced by combining Garamite-1958 with booster additives, such as RHEOBYK-R 605. The combination also allows for the transition from a pseudoplastic to a thixotropic rheology profile and for the reduction of thixotropic drift over time.Detergents, cleaning and care products
Special features and benefits
Garamite-1958 can be used in solvent systems within a wide polarity range from low polar to high polar. Suitable solvents include, for example, esters, vegetable oils, glycerol, aromatic compounds, mineral oils and silicone oils. It can also be used in nonionic surfactants (alcohol ethoxylates). Garamite-1958 is very easy to disperse and can be processed using low shear forces. It does not require an activator for gelling. Garamite-1958 produces excellent sagging resistance and effectively prevents settling and syneresis.Recommended levels
0.5–3% (as supplied) based upon the total formulation, depending on the properties of the formulation to be achieved.
The above recommended levels can be used for orientation. The optimum dosage should be determined by application-related test series.
Incorporation and processing instructions
Garamite-1958 can be incorporated either as a pregel or in situ.
Pregel can be produced as follows:- Place the organic solvent in the dispersion vessel
- Slowly add the Garamite-1958 (up to 20% based on the pregel) while stirring
- Mix for 15 minutes while stirring
Direct induction during production can be carried out as follows:
- Place the organic solvent or oil in the dispersion vessel
- Slowly add the Garamite-1958 while stirring
- Mix for 15 minutes while stirring
- Continue to add the other recipe components
The retrospective incorporation of Garamite-1958 to a finished system is also possible. Then higher shear forces are required and the temperature of the mix must be below 50 °C.
