MP-205 organic bentonite 
 MP-205 product is self-activated bentonite, can be added at any stage of paint, without pre-gel and the polar activator, distributed in the 20um fineness below can be used to paint and primer, providing paint rheological properties of the ideal system, control sedimentation and sagging, in addition to features with other similar products, MP-205 in the lower dosage, the high proportion of low-viscosity pigment flocculation system, the formation of a weak structure, to prevent the pigments sink node. This product can replace Bentone SD-1.

 Usage: 
 The bentonite in both solvent-based paint by adding dry powder can also be used to join pre-gel. However, pre-made gels with better play to the performance and effectiveness of organic soil. For poor wetting resin systems (such as epoxy, polyester, short oil alkyd resin, etc.) use the organic bentonite, pre-made pre-gel agreeable. 
 (1) pre-gel composition: 87% solvent, 8-10% organic soil, machine of the active agent 3-4%. 
 (2) pre-gel preparation process: Solvent + organic soil (mixture stirred for 10 minutes, fully wet), then add the polar activator (stirring 5 minutes, the full expansion). 
 Other: 
 (1) have appropriate shear dispersion and the time to make organic soil fully dispersed in the solvent. 
 (2) polar additives bentonite can be easier to help the formation of lamellar some lamellar structure, and the formation of thixotropic gel, machine additives (95% ethanol, 95% methanol, 100% acetone, 95% carbonate acrylic resin), the amount normally 30-50% of organic soil. 
 (3) organic soil must have sufficient water to enable it to develop into a network structure of the pre-gel, water molecules that form a grid structure of the bridge, so easy to over-drying of organic soil, moisture content of 3.5% for the general trade, machine sex additive is not easy to use water, the polar activator content of 95% for the prone (5% water). 
 (4) In order to fully disperse the pigment, which require the added surfactant, but it must be added after the model by adding activator, or the full spread of organic soil. 
 (5) addition of organic soil is generally 0.2-2% of the total system. 
 (6) organic soil in order to ensure full dispersion, polar organic soil activator must be added after wetting in the system, not the first Canadian polar activator, added organic soil. 
 (7) The best use of organic soil for one year, pay attention to moisture. 
 (8) through the FDA certification, organic bentonite harmless.
