Laponite can impartshear sensitive viscosity and improve syneresis control. Laponite products are also used toproduce antistatic Hazards IdentificationEmergency overviewMaterial can be slippery when wet.

2 Exposure to powder or dusts may be irritating to eyes, noseand throat. Health injuries are not known or expected under normal regulatory statusThis product is considered not hazardous under 29 CFR (Hazard Communication).Potential health effectsRoutes of in the eyes will cause or powder may irritate the skin. Health injuries are not known or expected under normal may irritate respiratory cause irritation. Health injuries are not known or expected under normal and symptomsNot componentsCAS #Percent3. Composition / Information on Ingredients53320-86-8100 Silicic Acid, Lithium Magnesium Sodium Salt4. First Aid MeasuresFirst aid proceduresEye contactGet medical attention if irritation develops or persists.

3 Flush eyes with water as a contactWash off with soap and water. Get medical attention if irritation develops or dust from the MATERIAL is inhaled, remove the affected person immediately to fresh air. Call aphysician if symptoms develop or mouth. If ingestion of a large amount does occur, seek medical to physicianNone adviceNo hazards which require special first aid Fire Fighting MeasuresFlammable propertiesNot a fire hazard. The product is not flammable. No unusual fire or explosion hazards noted. mediaSuitable extinguishingmediaUse fire-extinguishing media appropriate for surrounding extinguishingmediaNone name: Laponite RD370 Version #: 05 Revision date: Oct-02-2013 Print date: Oct-03-20131 / 6 MSDS USProtection of firefightersSpecific hazards arisingfrom the chemicalThe product itself does not burn.

4 No unusual fire or explosion hazards noted. MATERIAL can beslippery when equipment andprecautions for firefightersWear suitable protective equipment. Wear self-contained breathing apparatus and fightingequipment/instructionsNo unusual fire or explosion hazards methodsStandard procedure for chemical Accidental Release MeasuresPersonal precautionsKeep unnecessary personnel away. Local authorities should be advised if significant spillagescannot be contained. Avoid inhalation of dust from the spilled MATERIAL . Wear a dust mask if dustis generated above exposure precautionsDo not flush into surface water. Prevent further leakage or spillage if safe to do so. Do not letproduct enter drains.

5 Do not contaminate for containmentAvoid allowing water runoff to contact spilled MATERIAL . If sweeping of a contaminated area isnecessary use a dust suppressant agent which does not react with the product. Contaminatedsurfaces will be extremely for cleaning upShould not be released into the environment. Collect dust using a vacuum cleaner equipped withHEPA filter. Avoid dust formation. Following product recovery, flush area with water. For wastedisposal, see section 13 of the Handling and StorageHandlingProvide appropriate exhaust ventilation at places where dust is formed. In case of insufficientventilation, wear suitable respiratory not breathe dust from this MATERIAL . Avoid contact with skin and eyes.

6 Practice goodhousekeeping. Keep formation of airborne dusts to a minimum. Avoid release to the in a well-ventilated place. Keep container tightly closed. Avoid dust formation.

7 Ventilation ratesshould be matched to conditions. If applicable, use process enclosures, local exhaust ventilation,or other engineering controls to maintain airborne levels below recommended exposure limits. Ifexposure limits have not been established, maintain airborne levels to an acceptable level. Ifmaterial is ground, cut, or used in any operation which may generate dusts, use appropriate localexhaust ventilation to keep exposures below the recommended exposure protective equipmentEye / face protectionWear SAFETY glasses with side shields. Use tight fitting goggles if dust is protectionPVC or other plastic MATERIAL protectionIn case of insufficient ventilation, wear suitable respiratory equipment.
