Anti Block of the Film Silicon Dioxide BV809

Water Base Coating Silicon Dioxide BV809     Product Description           Gasoloid Matting agent(Gasoloid is the Matting Agent’s production way) is a type of  synthetic  chemical, amorphous silica dioxide, that has strong porosity and purity. Silica dioxide is one of the most substance in the world,but from chemical or physical character, Gasoloid silica dioxide is most difference from the nature silica dioxide.Through their character, we found the synthetical silica gel is good to the further application because of the powder shape structure, including the coating, gloss adjustment on the cloth, anti block of the film, activator’s carrier etc. Our BV809 gasoloid matting agent can special use in the high grade furniture paint.   Gasoloid Matting agent charater a) Porosity   It can be adjusted by man on the Gasoloid’s porosity, therefore, the different grades of gasoloid is manufacture by man, means we can control the size of the pore. Why matting agent have different kinds of absorption? Because it has the porosity and the different size of pore on the basis types. b) Formation and surface treatment of Matting agent  The gasoloid matting agent surface is covered by hydroxyl(-OH), its inner contains 2.5% - 3.0% weight of hydroxyl, this percentage is decided its quality grade. Hydroxyl(-OH) has strong hydrophilcity and easy to form the hydrogen bonding combination, those both have a react group of hydrogen, for example,hydroxyl or amino. Silica dioxide also have selective molecular, they have strong polarity. To treat the hydroxyl on the silica surface, BV805 had been treated by inorganic substance. c) Particle size and arrangement    The size of particle arrangement had been controlled during the certained range.   Matting agent grades and physical/chemical character a) Physical character ·Dry, white micron powder (amorphous)  ·Porosity ·Tasteless and odorless ·Refractive index: 1.46 ·Specific gravity : 2.15 b) Chemical character   The character is inactive(but can solve in the HF and high concentration alkali)   Safety   Matting agent is amorphous silica dioxide( the compound of containg water silica), under the Amorphous status, it is safe, moreover, our chemical is authority tested under the MSDS, showing its safe and enviromental.   BV809 character is as following,   Excellence hand feeling, BV809 particle surface is treated by organic wax, let the coatings film has good touch and smooth. Optimal anti settlement, BV809 paticle surface is treated by organic wax, moreover, the big pore volume, let the coatings and oil ink have good suspension and not easy to settle. Optimal matting effection, BV809 pore volume is up to 1.8ml/g, the particle size is 5.6um base on D50 average particle,let the coatings and oil ink has higher matting effection.   The main chemical index
