MP-200 organic bentonite 
 Organic bentonite - MP-200 product is a modified product, the product maintained a thickening performance, anti-settling, anti-flow registration, etc., it also has a white appearance of the product, the gel is colorless or light color, Higher transparency features, in addition, the product also has good dispersion properties and dispersion fineness. 
 Quality index: 
 Appearance White 
 Viscosity (7% xylene) ≥ 2.5 
 Size (200 mesh)% ≥ 95 
 Moisture content% ≤ 3.5 
 Loss on ignition% ≥ 35 
 Fineness of Dispersion (xylene)% ≤ 70 
 Polar solvent polarity range 
 The conditions required for glue dispersion 95% ethanol for polar activator 
 Application: 
 MP-200 products do not need polar activator can also be used for a wider range, suitable for low to medium polarity. Products from 
 In light color, transparency, and particularly suitable for classes and transparent paint, such as a transparent primer. Change the product not only transparent but also can improve the anti-yellowing properties. Corresponding grades: BENTONE 27 / 38 
 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
