Incorporation and Processing Instructions. The additive can be incorporated in different ways. Either disperse GARAMITE directly in the millbase or add it. GARAMITE® is a unique rheological additive developed for a wide range of solvent born systems. Compared to fumed silica and organoclays. Rheology additive based on mixed mineral technology for solvent-borne unsaturated polyester, epoxy and vinyl ester resins that provides excellent.

How to Use Garamite The use of Garamite is very similar to organoclays. When comparing MMTs to fumed silica, the big difference is in bulk densities. As organoclay manufacturers we impart a lot gaaramite energy to break this naturally occurring layered mineral apart. As with the previous study, we compared the MMT to a polyamide, conventional and self-activating organoclays, and a blank. Originally we used the Garamite only in Part A.

The information presented here was acquired by UL from the producer of the product or material or original information provider. The package viscosity tends to go higher and the sag and graamite resistance trend lower, making it difficult for the end user to provide a uniform surface to protect the substrate.
Certain quaternary amines work better in aliphatic vs. Including the other mineral type helps to prevent this gaamite occurring. Always be mindful of the fact the actual rheology of the finished system may not match exactly.
In recent studies we have seen the Garamite work across a very wide range of solvent systems. The comparison thixotropes need to achieve the correct temperature and dwell time garamie be activated and work properly, while Garamite does not.
To totally suspend the zinc it took 1. Byk invests approximately 7.
Cowles-type shear will suffice in all applications for dispersing the MMTs. However, UL assumes no responsibility or liability for the accuracy of the information contained on this website and strongly encourages that upon final product garaamite material selection information is validated with the manufacturer. This pregel was both pourable and pumpable Figure This system turned out to be a little more difficult than the previous system, as it took the higher 4 pounds per gallon level of Garamite to eliminate the settling.
We will now recommend some starting use levels, keeping in mind that we are talking in generalities, and some systems have different demands than expected. In this case the polyamide had the highest viscosity but did not do well for the prevention of settling during heat aging Figure 9.

This morphology plays a role in not only the ease of incorporation, but also in the efficacy of sag resistance and settling resistance over heat aging.
Keep in mind that the viscosity may be lower, but the sag resistance should be greater. If solvent is not available, then add the Garamite to a reactive diluent or garammite the lowest-viscosity resin, with the first choice being the diluent. Garamite has a unique morphology of rods and plates as compared to conventional organoclays that use just a plate-like layered structure Figure 2. This page can be found at http: They are off-white powders that are organically modified and have a specific gravity of about 1.
These organoclays usually are more efficient for thickening, but can be more difficult to incorporate, and order of addition can be more critical.
Not only is sag resistance increased, but runs are reduced or eliminated Figure 3. We have shown that Garamite fills this need agramite many cases as compared to conventional organoclays, polyamides and fumed silicas. Also, it may be possible to use these products during manufacture without the ideal conditions, yet still pass QC. We also found that the quaternary garamire does not play as important a role in determining efficiency in a specific solvent system, like with traditional organoclays.
This higher level of quaternary amine typically makes them easier to incorporate, but slightly less efficient than traditional organoclays, all other things being equal. Epoxy Floor Coating Figure garanite highlights the suspension of quartz sand in an epoxy floor coating.
However, this property is not noticed in filled systems. It is also more efficient and easier to handle in manufacturing less dusty, higher bulk density and not sensitive to shear.
When working with epoxies do not be afraid to try various combinations between Part A and Part B. While the MMTs have a low bulk density compared to traditional organoclays, it is much higher than fumed silica, which has an extremely low bulk density.
But for reactivity and storage stability it should be tested to see if the water in Garamite causes issues in these watersensitive formulations. Another advantage of the MMTs is that in most systems polar activators are not necessary. Organoclays are typically made from smectite and garaamite in a form graamite like a deck of cards, with clay particles Stacked one garamit another.
