COMPOSITION / INFORMATION ON INGREDIENTSHazardous Component(s)CAS NumberPercentage*SaccharinEthene, homopolymerCumene hydroperoxideCumeneMethyl -51-51-50.1 - 10.1 - 1* Exact percentages may vary or are trade secret. Concentration range is provided to assist users in providing appropriate protections.4. FIRST AID MEASURESInhalation:Move to fresh air. If breathing is difficult, give oxygen. If not breathing, giveartificial respiration. Get medical attention.Skin contact:Immediately flush skin with plenty of water (using soap, if available). Removecontaminated clothing and footwear. Wash clothing before reuse. Get medicalattention.Eye contact:Rinse immediately with plenty of water, also under the eyelids, for at least 15minutes. Get medical attention.Ingestion:DO NOT induce vomiting unless directed to do so by medical personnel.Never give anything by mouth to an unconscious person. Get medicalattention.Symptoms:See Section 11.5. FIRE FIGHTING MEASURESExtinguishing media:Water spray (fog), foam, dry chemical or carbon dioxide.Special firefighting procedures:Wear self-contained breathing apparatus and full protective clothing, such asturn-out gear. In case of fire, keep containers cool with water spray.Unusual fire or explosion hazards:Uncontrolled polymerization may occur at high temperatures resulting inexplosions or rupture of storage containers.Hazardous combustion products:Oxides of carbon. Oxides of nitrogen. Irritating vapors.6. ACCIDENTAL RELEASE MEASURESUse personal protection recommended in Section 8, isolate the hazard area and deny entry to unnecessary and unprotectedpersonnel.Environmental precautions:Do not allow product to enter sewer or waterways.Clean-up methods:Remove all sources of ignition. Evacuate and ventilate spill area; dike spill toprevent entry into water system; wear full protective equipment during cleanup. Soak up with inert absorbent material (e.g. sand, silica gel, acid binder,universal binder, sawdust). Scrape up as much material as possible. Store in apartly filled, closed container until disposal. Refer to Section 8 "ExposureControls / Personal Protection" prior to clean up.IDH number: 231926Product name: LOCTITE 262 THREADLOCKER HIGH STRENGTHPage 2 of 6

7. HANDLING AND STORAGEHandling:Use only with adequate ventilation. Prevent contact with eyes, skin andclothing. Do not breathe vapor and mist. Wash thoroughly after handling.Keep container closed. Refer to Section 8.Storage:For safe storage, store between 0 C (32 F) and 32 C (89.6 F)Keep in a cool, well ventilated area away from heat, sparks and open flame.Keep container tightly closed until ready for use.8. EXPOSURE CONTROLS / PERSONAL PROTECTIONEmployers should complete an assessment of all workplaces to determine the need for, and selection of, proper exposurecontrols and protective equipment for each task performed.Hazardous Component(s)SaccharinACGIH TLVOSHA PELAIHA WEELOTHERNoneNone15 MPPCF TWARespirable fraction.15 mg/m3 TWA Totaldust.50 MPPCF TWATotal dust.5 mg/m3 TWARespirable fraction.5 mg/m3 PELRespirable fraction.15 mg/m3 PEL Totaldust.NoneNoneNoneNoneEthene, homopolymer10 mg/m3 TWAInhalable particles.3 mg/m3 TWARespirable particles.Cumene hydroperoxideNoneNone1 ppm (6 mg/m3)TWA(SKIN)None50 ppm TWA50 ppm (245 mg/m3)PEL(SKIN)NoneNone50 ppm TWA100 ppm STEL(Dermal sensitization)100 ppm (410mg/m3) PELNone50 ppmCumeneMethyl methacrylateEngineering controls:Provide adequate local exhaust ventilation to maintain worker exposure belowexposure limits.Respiratory protection:Use NIOSH approved respirator if there is potential to exceed exposurelimit(s).Eye/face protection:Safety goggles or safety glasses with side shields. Full face protection shouldbe used if the potential for splashing or spraying of product exists. Safetyshowers and eye wash stations should be available.Skin protection:Use chemical resistant, impermeable clothing including gloves and either anapron or body suit to prevent skin contact.
