Based onits composition, it is anticipated to be slightly toxic if swallowed or absorbed through skin, practically non-toxic if inhaled,slightly irritating to skin and practically non-irritating to eyes. Repeated or prolonged contact may cause an allergic skinreaction. High vapor concentrations may be irritating to the eyes and respiratory tract, and may result in centralnervous system (CNS) effects such as headache, dizziness, nausea, drowsiness and, in severe exposures, loss ofProduct Code: RSO00 Revision: 13 Issued: 19 OCT 2004Page 1 of 6

Remove contaminated clothing and shoes.Get medical attention if symptoms occur. Wash clothing before reuse. Thoroughly clean shoes before reuse.IF SWALLOWED, induce vomiting immediately as directed by medical personnel. Get medical attention.NEVER GIVE ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON.IF INHALED, remove to fresh air.5 FIRE FIGHTING MEASURESFire and Explosive PropertiesAuto-Ignition TemperatureFlash PointFlammable Limits- UpperLowerNENENENEFlash Point MethodExtinguishing MediaUse water spray, carbon dioxide, foam or dry chemical.Fire Fighting InstructionsFire fighters and others who may be exposed to products of combustion should wear full fire fighting turn outgear (full Bunker Gear) and self-contained breathing apparatus (pressure demand NIOSH approved orequivalent). Fire fighting equipment should be thoroughly decontaminated after use.Fire and Explosion HazardsWhen burned, the following hazardous products of combustion can occur:Oxides of carbonTin oxides6ACCIDENTAL RELEASE MEASURESIn Case of Spill or LeakIsolate hazard area and deny entry to unnecessary or unprotected personnel. Contain spilled liquid withsand or earth. Clean up spill immediately, observing precautions in the Personal Protection section ofMSDS. Avoid runoff into storm sewers and ditches which lead to waterways.7HANDLING AND STORAGEHandlingAvoid prolonged or repeated contact with skin. Wash thoroughly after handling. Use only with adequateventilation.Product Code: RSO00 Revision: 13 Issued: 19 OCT 2004Page 2 of 6

THERMOLITE (R) 190Material Safety Data SheetArkema Inc.7HANDLING AND STORAGEStorageStore in a cool, dry place. Keep away from heat, sparks and flame. Keep containers tightly closed. Do NOTstore near strong acids. Material can burn; limit indoor storage to areas equipped with appropriate automaticsprinkler system.8EXPOSURE CONTROLS / PERSONAL PROTECTIONEngineering ControlsInvestigate engineering techniques to reduce exposures below airborne exposure limits. Provide ventilationif necessary to control exposure levels below airborne exposure limits (see below). If practical, use localmechanical exhaust ventilation at sources of air contamination such as open process equipment.Eye / Face ProtectionWhere there is potential for eye contact, wear chemical goggles and have eye flushing equipment available.Skin ProtectionWear appropriate chemical resistant protective clothing and chemical resistant gloves to prevent skincontact. Consult glove manufacturer to determine appropriate type glove material for given application.Wear face shield and chemical resistant clothing such as a rubber apron when splashing may occur. Rinsecontaminated skin promptly. Wash contaminated clothing and clean protective equipment before reuse.Wash skin thoroughly after handling.Respiratory ProtectionAvoid breathing vapor or mist. When airborne exposure limits are exceeded (see below), use NIOSHapproved respiratory protection equipment appropriate to the material and/or its components. Consultrespirator manufacturer to determine appropriate type equipment for given application. Observe respiratoruse limitations specified by NIOSH or the manufacturer. For emergency and other conditions whereexposure limit may be significantly exceeded, use an approved full face positive-pressure, self-containedbreathing apparatus or positive-pressure airline with auxiliary self-contained air supply. Respiratoryprotection programs must comply with 29 CFR § 1910.134.Airborne Exposure Guidelines for IngredientsExposure LimitOrganotin mercaptideACGIH Skin designatorACGIH STELACGIH TWAOSHA TWA PELOrganotin mercaptideACGIH Skin designatorACGIH STELACGIH TWAOSHA TWA PEL--------ValueY0.2 mg/m30.1 mg/m30.1 mg/m3Y0.2 mg/m30.1 mg/m30.1 mg/m3-Only those components with exposure limits are printed in this section.-Skin contact limits designated with a "Y" above have skin contact effect.

Repeated administration in the dietof rats produced pathological changes in the kidneys. Long-term administration in the diet of rats produced noadverse effects and no tumors were observed. No effects were seen on the ability of male or female rats toreproduce following administration in the diet for 2 successive generations. This material produced no geneticchanges in standard tests using bacterial cells.MercaptanSingle exposure (acute) studies indicate that this material is moderately toxic if swallowed (rat LD50 303 mg/kg),no more than slightly toxic if absorbed through skin (rat LD50 >2,000 mg/kg) or inhaled (rat 6-hr LC0 0.51 mg/l),non-irritating to rabbit eyes and slightly irritating to rabbit skin.Product Code: RSO00 Revision: 13 Issued: 19 OCT 2004Page 4 of 6

THERMOLITE (R) 190Material Safety Data SheetArkema Inc.11TOXICOLOGICAL INFORMATIONExposure of workers resulted in headaches, dizziness, fatigue, weariness and gastrointestinal symptoms. Skinallergy was observed in guinea pigs following repeated exposure. An increase in mortality was noted in ratsfollowing short-term oral exposure (NOEL 150 mg/kg) and in rats and guinea pigs following repeated dermalapplication. Slight liver, kidney and blood effects were noted in one study following repeated dietaryadministration to rats. Generally, no genetic changes were observed in tests using bacteria, animal cells oranimals.12ECOLOGICAL INFORMATIONEcotoxicological InformationData on this material and/or its components are summarized below.Organotin MixtureThis material is practically non-toxic to algae (96-hr EC50 260 mg/l), mysid shrimp (96-hr LC50 170 mg/l) andfathead and sheepshead minnows (96-hr LC50 >1,000 mg/l).
