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.

To totally suspend the zinc it took 1. The morphology also plays a role in ease of incorporation. The information garamige here was acquired by UL from the producer of the product or material or original information provider.
A Novel Mixed Mineral Thixotrope Technology For Industrial Coatings, Southern Clay Products
However, this property is not noticed in filled systems. This flexibility could reduce the number of thixotropes needed. When comparing MMTs to fumed silica, the big difference is in bulk densities. They also require the proper agitation during cooling in order to prevent the system from forming a false body.
Organoclay Rheological Additive Sg-58 Counter to Garamite 1958
The Garamite should be added at a percentage high enough to make a pregel that is still pourable. You gzramite choose a language below to continue to this industry or close this dialog above.
Conclusions As coating formulations move to lower VOCs and higher solids, the demand on the thixotrope becomes more difficult as it pertains to package viscosity, sag and settling resistance. While ggaramite completely necessary, this will consistently yield the most efficient results. This morphology plays a role in not only yaramite ease of incorporation, but also in the efficacy of sag resistance and settling resistance over heat aging. Even though the polyamide yielded the highest viscosity, the Garamite at the lowest level, 2 pounds per gallons, had a settling resistance that matched the higher loading level of polyamide Figure 8.
Originally we used the Garamite only in Part A. This is garaite the first time in this article we use a rheological enhancer, the BYK R A simple way to look at organoclay is to look at the level and type of quaternary amine modification on the clay.
But it does mean MMTs are more flexible as compared to organoclays and have the ability to work in more systems. Having the ability to make pourable high-solids pregels makes it easier to formulate in systems where one has low levels of solvents Figure 4. The water garamiye adhering to the clay surface and is not automatically available for reaction with the isocyanate.
This article explains how and why Garamite works. Also, it bears mentioning that some color is imparted into clear, unfilled systems by the MMT. This pregel was both pourable and pumpable Figure If solvent is not available, then add the Garamite to a reactive diluent or to the lowest-viscosity resin, with the first choice being the diluent. How to Use Garamite The use of Garamite is very similar to organoclays. This class of material is used from time to time to boost or enhance the properties of the thixotrope.
Self-activating organoclays tend to have a higher loading of quaternary amine on them. Are you a distributor who is interested in being listed here?
It is also more efficient and easier to handle in manufacturing less dusty, higher bulk density and not sensitive to shear. Keep in mind that the gafamite may be lower, but the sag resistance should be greater. However, the Garamite will still in most cases maintain an advantage over other competitive materials. If needed to gain gqramite little more efficiency, one can use polar activators in a manner similar to traditional organoclays.
While the efficiency was there we discovered that the sag resistance fell off during the pot life. Company Byk has an established history of innovation such as being the first additive manufacturer to begin using Controlled Polymerization Technology CPTlaunching the first rheology-modified wax emulsion, and being one of the first companies to use nanotechnology for improving Coatings properties.
In this study we compared the MMT to a polyamide, both conventional and selfactivating organoclays, as well as a blank.
Properties such as sag 198 and settling resistance become garamie difficult to balance with package viscosity. Other incorporation methods can also be used. When working with epoxies do not be afraid to try various combinations between Part A and Part B.
Powdered rheology additive: GARAMITE
Garamite outperforms fumed silica and significantly outperforms conventional organoclay. However, MMT networks use different spacing than do traditional organoclays, due to the different particle shapes involved. 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.
