Ensure that eyewash stations and safety showers are proximal to thework-station location.Personal ProtectionVentilation : Good general ventilation should be sufficient to control airborne levels.Respiratory system :Skin Contact :Eyes :Other information :Wear appropriate respirator when ventilation is inadequate.Use chemical resistant, impervious gloves. ( Nitrile. ) Work uniform or laboratory coat.Safety glasses with side shields or chemical splash goggles.Wear nitrile or other chemical resistant gloves to avoid skin contact when handling partially cured fabricatedobjects in the "green" state of cure (after initial laser cure). The fabricated objects may be handled withoutgloves after the object has been thoroughly washed with solvent (ex. tripropylene glycol monomethyl ether,isopropyl alcohol) followed by post exposure to UV light and/or an oven bake at temperatures aboves 130 o C.When sanding fully cured surfaces, suitable respirator protection for dust should be used. Good generalventilation is required when tooling or sanding to avoid inhalation of particulate matter or airborne particles.Avoid sanding or finishing parts that are not fully cured, as uncured material may cause skin sensitization orrespiratory irritation.9.

10. Stability and ReactivityStabilityHazardous PolymerizationIncompatibility, Conditions to avoid,Materials to avoidHazardous Decomposition Products:The product is stable.: Not likely under normal conditions.::Keep away from direct sunlight or strong incandescent light. Keep away from heat.May react or be incompatible with acids. Incompatible with peroxides.Possibly hazardous short term degradation products are not likely. However, longterm degradation products may arise.11. Toxicological InformationRoutes of EntryToxicologicalInformationSkin, eyes and respiratory tract.Acute oral toxicity (LD50): >5000 mg/kg [Rat]. (acrylate).Acute dermal toxicity (LD50): >20 mg/kg [Rabbit]. (triethylene glycol).Remarks: Any information in this section is for component(s) contained in this product.Epoxy: Acute Toxicity:Peroral: rat; LD50 5000 mg/kg; approximatelyPercutaneous: rabbit; LD50 =>23000 mg/kgDevelopmental Toxicity:Did not cause birth defects in laboratory animals. Has been toxic to the fetus in lab animals at doses toxic tothe mother.Reproductive Toxicity:Limited data in laboratory animals suggest that the material does not affect reproduction.Chronic Toxicity and Carcinogenicity:Did not cause cancer in animal skin painting studies.Genetic Toxicology:In vitro: In vitro genetic toxicity studies were negative in some cases and positive in other cases.In vivo: Animal genetic toxicity studies were negative.Significant Data with Possible Relevance to Humans:In animals, effects have been reported on the following organs: Kidney, liver and upper respiratory tract.Epoxy Resin Mixture: Acute Effects:eye irritation: Draize - 2 (rabbit)skin irritation: Draize - 1.6 (rabbit)Chronic Health Effects:Carcinogenicity:Recent 2-year bioassays in rats and mice exposed by the dermal route to the component yielded no evidenceof carcinogenicity to the skin or any other organs. This study clarifies prior equivocal results from a 2-yearmouse skin painting study, which were suggestive, but not conclusive. for weak carcinogenic activity. TheInternational Agency for Research on Cancer (IARC) concluded that this component is not classifiable as acarcinogen (IARC group 3), that is human and animal evidence of carcinogenicity is inadequate.Mutagenicity:Similar resins have proved to be inactive when tested by in vivo mutagenicity assays. These resins haveshown activity in invitro mircobial mutagenicity screening and have produced chromasomal aberrations incultured rat liver cells.acrylate: A 13-week inhalation study in rats of a compositionally similar acrylic powder showed inflammatoryeffects in the lung at concentrations of 6 mg/m3 for 6 hours per day, 5 days per week. These findings wereconsistent with high concentration exposure effects reported for other non-soluble dusts such as titaniumdioxide and toner. Maintaining airbone dust concentrations within the recommended exposure limit is notexpected to produce adverse effects within the lung.diethylene glycol: There is a marked difference in the acute oral toxicity of this material between animals andman. Man is much more susceptible than animals. The estimated fatal dose for man is 1.2 mg/kg (100 mL or1/2 cup for a 82 kg or 180 lb man).Photoinitiator: This material was mutagenic in the Ames bacterial assay. It is inactive, however, in the in vivomouse micronucleus test.Chronic effects onhumansCARCINOGENIC EFFECTS: Classified None. by IARC, None. by OSHA, None. by NTP [SOMOS® DMX-SL100].Remarks: Any information contained in this section is for component(s) contained in this product.Not available.SOMOS® DMX-SL 100 Version 1 Page Number: 4/5
