AQUEOUS SLURRIES raiding down your production rate?
Complete visibility
ADD MARASPERSE DISPERSANTS to make them thinner and easier to handle. Completely corrosion resistant
The Marasperses keep small particles of insoluble solids dispersed, won't let them flocculate or "get together" in water. In slurries this means greater fluidity, because the smaller particles flow past one another more readily than do the larger ones. And in dilute suspensions, it means better suspensibility, because small particles remain suspended longer than do the more sizeable ones.
Patented seat
So, if your products have to be suspended in water for use, avoid customer complaints about sedimentation by using Marasperses in your formulations.
High heat resistance
A completely new concept in relief valve seat design plus*Pyrex & Teflon Construction for the added advantages of full visibility and corrosion resistance Seat pressure is completely independent of spring load. Valve reseats after venting without labor or material cost of rupture disc replacement. Ideally suited for both pressure and vacuum relief. Seals against liquids and gases. Use with liquid lines, with reactors and vessels of all types. Available in other materials of construction. Ask us for Bulletin RV-1
Only a little Marasperse is required to achieve a stabilized dispersion. Usually less than 3% ( based on the weight of the solids in an aqueous system) will do the job for you. Pigment dispersions, for example, need only 1 or 2% Marasperse . . . likewise, ceramic clay dispersions and dyestuff pastes. What's more, Marasperses are inexpensive, too!
It's easy to determine whether or not a dispersant can be useful to you. A few quick tests in your laboratory will provide the answer. Write us about your viscosity or suspensibility problems. We'll send you suitable Marasperse samples for evaluation, together with descriptive literature.
*T.M., Corning Glass Works A NEW LINE OF CORROSION RESISTANT FILTERS Permanent filter element offers maximum particle retention with very high flow rate. Porosity ranee, one to 100 microns. Use for sterilization, clarifying, polishing. Pyrex & Teflon construction for visibility and high temperature applications. Write for Bulletin FPT-2.
