GARAMITE 1958 PDF

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.

This pregel was both pourable and pumpable Figure This class of material is used from time to time to boost or enhance the properties of the thixotrope. The package viscosity tends to go higher and the sag and settling resistance trend lower, making it difficult for the end user to provide a uniform surface to protect the substrate. Another key advantage to the coatings manufacturer is the ability to make high-solids premixes at pourable viscosities.

They also require the proper agitation during cooling in order to prevent the system from forming a false body. Unlike organoclays, Garamite is easily incorporated into the coating formulation without using a high level of quaternary amine. One advantage for fumed silica is clarity in the final film.

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.

Originally we used the Garamite only in Part A. Garamite is significantly easier to incorporate when compared to polyamides and castor derivatives and does not have their temperature and dwell time limitations.

MMT Advantages In practical terms we have found that Garamite tends to build less package viscosity while providing more sag resistance than organoclays.

While not completely necessary, this will consistently yield the most efficient results. You may choose a language below to continue to this industry or close this dialog above. But in the end, Mother Nature tries to return the clay back to its natural state.

In this case the polyamide had the highest viscosity but did not do well for the prevention of settling during heat aging Figure 9.

Zinc The next study intended to find the level of Garamite ggaramite to suspend zinc through the use of high-solids pregels. Other incorporation methods can also be used.

This allows for lower package viscosity, lower cost and increased ease of manufacture. The information presented here was acquired by UL from the producer of the product or material or original information provider. However, the Garamite will still in most cases maintain an advantage over other competitive materials. Byk makes their documentation available in the regions indicated below: This higher level of quaternary amine typically makes them easier to incorporate, but slightly less efficient than traditional organoclays, all other things being equal.

The faramite levels, considered to be traditional organoclays, have to be activated with some type of polar activator.

It is not unusual for the package viscosity to be lower and the sag resistance to be higher. Be sure to test for compatibility and stability. As you move from solvent to diluent to resin the efficiency will drop somewhat. It is also more efficient and easier to handle in manufacturing less dusty, higher bulk density and not sensitive to shear. But it does mean MMTs are more flexible as compared to organoclays and have the ability to work in more systems.

If needed to gain a little more efficiency, one can use polar activators in a manner similar to traditional organoclays. Another advantage of the MMTs is that in most systems polar activators are not necessary. Industrial White Topcoat The next study looked at an industrial white topcoat. This page can be found at http: In unfilled systems, another shortcoming would be that the MMTs do not perform quite as well for sag resistance.

In part, we believe this has to do with the difference in having a combination of rods and plates and having more spacing, making it much more difficult for Mother Nature to put the clay back to its natural state.

Powdered rheology additive: GARAMITE

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.

Self-activating organoclays tend to have a higher loading of quaternary amine on them. When working with epoxies do not be afraid to try various combinations between Part A and Part B.
