Dushura Garamite Compared to Organoclay There are a variety of organoclays, but for the purpose of this article we will stick to the basics and compare and contrast activated versus self-activating organoclays. Garamite has a unique morphology of rods and plates as compared to conventional organoclays that use just a plate-like layered structure Figure 2. When comparing Garamite to garaimte or castor derivatives, the MMT is much less sensitive to processing conditions. It is also more efficient and easier to handle in manufacturing less dusty, higher bulk density and not sensitive to shear. How to Use Garamite The use of Garamite is very similar to organoclays.

Placement can be important to both pot life and shelf life and should be tested. Always be mindful of the fact the actual rheology of the finished system may not match exactly. Garamite has a unique morphology of rods and plates as compared haramite conventional organoclays that use just a plate-like layered structure Figure 2.
MMT Advantages In practical terms we have found that Garamite tends to build less package viscosity while providing more sag resistance than organoclays. Other incorporation methods can also be used. The lowest levels, considered to be traditional organoclays, have to be activated with some type of polar activator.
When working with epoxies do not be afraid to try various combinations between Part A and Part B. 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. When comparing MMTs to fumed silica, the big difference is in bulk densities.
Unlike organoclays, Garamite is easily incorporated into the coating formulation without using a high level of quaternary amine. Industrial White Topcoat The next study looked at an industrial white topcoat. Notice the phase separation of the modification made with organoclay. However, UL assumes no responsibility or liability for the accuracy of the information contained on this website and strongly encourages that upon final product or material selection information is validated with the manufacturer.
One advantage for fumed silica is clarity in the final film. How MMTs Work MMTs thicken systems similarly to the way in which organoclays work, using hydrogen bonding to form a three-dimensional network Figure 1.
Including the other mineral type helps to prevent this from occurring. Another key advantage to the coatings manufacturer is the ability to make high-solids premixes at pourable viscosities. The Garamite should be added at a percentage high enough to make a pregel that is still pourable.
As with the previous study, we compared the MMT to a polyamide, conventional and self-activating organoclays, and a blank.
Certain quaternary amines work better in aliphatic vs. However, the Garamite will still in most cases maintain an advantage over other competitive materials. Epoxy Floor Coating Figure 7 highlights the suspension of quartz sand in an epoxy floor coating. 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.
Another advantage of the MMTs is that in most systems polar activators are not necessary. Be sure to test for compatibility and stability. We have shown that Garamite fills this need in many cases as compared to conventional organoclays, polyamides and fumed silicas. This website provides links to other websites owned by third parties. Originally we used the Garamite only in Part A. To totally suspend the zinc it took 1. Organoclays are typically made from smectite and come in a form somewhat like a deck of cards, with clay particles Stacked one upon another.
Also the type of quaternary amine modification determines which type of solvent system the organoclay will work best in. 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.
This higher level of quaternary amine typically makes them easier to incorporate, but slightly less efficient than traditional organoclays, all other things being equal. Related Posts.
Doshicage Keep in mind that the viscosity may be lower, but the sag resistance should be greater. 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 garakite for improving Coatings properties. Certain quaternary amines work better in aliphatic vs. The Garamite should be added at a percentage high enough to make a pregel that is still pourable.

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. China Rheological Additive Counter to Garamite — China Organoclay, Rheological Additive The information presented here was acquired by UL from the producer of the product or material or original information provider.
