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.

Mixed Mineral Thixotropes MMTs are a combination of two different morphologies; one being a plate, the other being a rod. This flexibility could reduce the number of thixotropes needed. While not completely necessary, this will consistently yield the most efficient results. Other incorporation methods can also be used. This becomes more important as VOC goes down and solids go up. If needed to gain a little more efficiency, one can use polar activators in a manner similar to traditional organoclays.
It is as though the MMT needs to space something to work. Are you a distributor who is interested in being listed here? Then somewhere down the road the system may have seeding problems or lose stability. How to Use Garamite The use of Garamite is very similar to organoclays.
It is also more efficient and easier to handle in manufacturing less dusty, higher bulk density and not sensitive to shear. This pregel was both pourable and pumpable Figure 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.
Byk makes their documentation available in the regions indicated below: Polyurethane Systems Other potential applications include polyurethanes, epoxy adhesives and grouts, unsaturated polyesters, metallic coatings and aerosol coatings.
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.
Not only is sag resistance increased, but runs are reduced or eliminated Figure 3. As you move from solvent to diluent to resin the efficiency will drop somewhat. How MMTs Work MMTs thicken systems similarly to the way in which organoclays work, using hydrogen bonding to form a three-dimensional network Gqramite 1. The lowest levels, considered to be traditional organoclays, have to be activated with some type of polar activator.
Organoclay Rheological Additive Sg-58 Counter to Garamite 1958
Does this mean it will work every time? This article explains how and why Garamite works. However, the Garamite will still in most cases maintain an advantage over other competitive materials. To totally suspend the zinc it took 1.
GARAMITE® by Byk – Paint & Coatings
Industrial White Topcoat The next study looked at an industrial white topcoat. Stability can be lost in different areas, whether it be sag resistance 195 off or package viscosity rising substantially. While polyamides in particular may be among the best at yielding garamiye perfect buttery feel, they are much less forgiving during manufacture than MMTs.
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.
We then realized that by splitting the Garamite 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. When comparing MMTs to fumed silica, the big difference is in bulk densities.
The water is adhering to the clay surface and is not automatically available for reaction with the isocyanate. We also found that the quaternary amine does not play as important a role in determining efficiency in a specific solvent system, like with traditional organoclays. Another advantage of the MMTs is that in most systems polar activators are not necessary.
