TSCA 8(b) inventory: VAROX® DCP-40KE Powder Product Name/ Trade Name Synonym Chemical name Chemical Formula Chemical Family Material Uses CAS# Code VAROX® DCP-40KE Powder Dicumyl Peroxide 40% Dicumyl peroxide on clay Not applicable. Organic Peroxide Mixture 71063 Industrial applications: Polymerisation initiator Section I. Chemical Product and Company Identification Supplier In Case of Emergency Material Safety Data Sheet R.T. VANDERBILT COMPANY, INC. 30 WINFIELD STREET NORWALK, CT 06855 Call: (203) 853-1400 TSCA Status chemusa Section II. Composition and Information on Ingredients Name CAS # % by Weight dicumyl peroxide 80-43-3 40 Burgess KE clay 66402-68-4 60 Section III. Hazards Identification Emergency Overview Off-white powder with faint odor. Organic peroxide. Heat or contamination with strong acids causes gaseous decomposition. May cause eye and skin irritation. Inhalation of high concentrations may cause irritation or discomfort. Do not induce vomiting. Loosen tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing, perform mouth-to-mouth resuscitation. Seek immediate medical attention. Eye Contact Skin Contact Inhalation Ingestion Check for and remove any contact lenses. Flush with running water for at least 15 minutes. Do not use an eye ointment. Seek medical attention. After contact with skin, wash immediately with plenty of water. Gently and thoroughly wash the contaminated skin with running water and non-abrasive soap. Be particularly careful to clean folds, crevices, creases and groin. Cover the irritated skin with an emollient. If irritation persists, seek medical attention. Wash contaminated clothing before reusing. Allow the victim to rest in a well ventilated area. Loosen clothing and seek immediate medical attention Section IV. First Aid Measures Continued on Next Page VAROX® DCP-40KE Powder Page Number: 2 Autoignition Temperature Products of Combustion Flash Point Fire Fighting Media and Instructions Flammable Limits Not available.

Risks of explosion of the product in presence of static discharge: Not available. Not available. Section V. Fire and Explosion Data Special Remarks on Explosion Hazards Special Remarks on Fire Hazards Explosion Hazards in Presence of Various Substances Flammability of the Product Section VI. Accidental Release Measures Small Spill Large Spill Put spilled solid in a waste disposal container. Oxidizing Material Organic peroxide. Stop leak if without risk. Avoid contact with a combustible material (wood, paper, oil, clothing...). Keep substance damp using water spray. Do not use metal tools or equipment. Do not touch spilled material. Use water spray to reduce vapors. Prevent entry into sewers, basements or confined areas; dike if needed. Eliminate all ignition sources. Call for assistance on disposal. Be careful that the product is not present at a concentration level above TLV. Check TLV on the MSDS and with local authorities. Storage Store below 30°C to maintain maximum quality. Detached storage is preferred. Avoid excessive heat and store out of direct sunlight in a cool well-ventilated place. Store away from combustibles and incompatibles. Section VII. Handling and Storage Handling Procedures and Equipment Store and use away from heat, sparks, open flame, or any other ignition source. Ground all equipment containing material. Engineering Controls Personal Protection Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits. If user operations generate dust, fume or mist, use ventilation to keep exposure to airborne contaminants below the exposure limit. Splash goggles. Lab coat. Dust respirator. Be sure to use an approved/certified respirator or equivalent. Gloves. Section VIII. Exposure Controls/Personal Protection TLV / PEL dicumyl peroxide TWA: 5 (mg/m3) from OSHA (PEL) Respirable.
