FIREFIGHTING MEASURES Suitable extinguishing media: Water spray Alcohol-resistant foam Carbon dioxide (CO2) Dry chemical Unsuitable extinguishing media: None known. Special hazards arising from the substance or mixture Hazardous combustion products: Carbon oxides Nitrogen oxides (NOx) Chlorine compounds Oxides of phosphorus Silicon oxides Formaldehyde Page 2 of 12 Product name: DOWSIL™Instantglaze III Assembly Adhesive Issue Date: 03/12/2018 Translucent Unusual Fire and Explosion Hazards: Exposure to combustion products may be a hazard to health. Advice for firefighters Fire Fighting Procedures: Use extinguishing measures that are appropriate to local circumstances and the surrounding environment. Use water spray to cool unopened containers. Collect contaminated fire extinguishing water separately. This must not be discharged into drains. Remove undamaged containers from fire area if it is safe to do so. Evacuate area. Special protective equipment for firefighters: In the event of fire, wear self-contained breathing apparatus. Use personal protective equipment. 6. ACCIDENTAL RELEASE MEASURES Personal precautions, protective equipment and emergency procedures: Use personal protective equipment. Follow safe handling advice and personal protective equipment recommendations. Environmental precautions: Discharge into the environment must be avoided. Prevent further leakage or spillage if safe to do so. Retain and dispose of contaminated wash water. Local authorities should be advised if significant spillages cannot be contained. Methods and materials for containment and cleaning up: Sweep up or vacuum up spillage and collect in suitable container for disposal. Local or national regulations may apply to releases and disposal of this material, as well as those materials and items employed in the cleanup of releases. You will need to determine which regulations are applicable. Sections 13 and 15 of this SDS provide information regarding certain local or national requirements. See sections: 7, 8, 11, 12 and 13. 7. HANDLING AND STORAGE Precautions for safe handling: Do not get on skin or clothing. Do not swallow. Avoid contact with eyes. Take care to prevent spills, waste and minimize release to the environment. Handle in accordance with good industrial hygiene and safety practice. Use only with adequate ventilation. See Engineering measures under EXPOSURE CONTROLS/PERSONAL PROTECTION section. Conditions for safe storage: Keep in properly labelled containers. Store in accordance with the particular national regulations. Do not store with the following product types: Strong oxidizing agents. Unsuitable materials for containers: None known.

EXPOSURE CONTROLS/PERSONAL PROTECTION Control parameters If exposure limits exist, they are listed below. If no exposure limits are displayed, then no values are applicable. Methanol ACGIH TWA 200 ppm ACGIH STEL 250 ppm ACGIH TWA SKIN OSHA Z-1 TWA 260 mg/m3 200 ppm ACGIH STEL SKIN Although some of the components of this product may have exposure guidelines, no exposure would be expected under normal handling conditions due to the physical state of the material. The following substance(s), which have Occupational Exposure Limit(s) (OEL), may be formed during handling or processing: Methanol. Biological occupational exposure limits Components CAS-No. Control Biological Sampling Permissible Basis parameters specimen time concentration Methanol 67-56-1 Methanol Urine End of 15 mg/l ACGIH shift (As BEI soon as possible after exposure ceases) Exposure controls Engineering controls: Use local exhaust ventilation, or other engineering controls to maintain airborne levels below exposure limit requirements or guidelines. If there are no applicable exposure limit requirements or guidelines, general ventilation should be sufficient for most operations. Local exhaust ventilation may be necessary for some operations. Individual protection measures Eye/face protection: Use safety glasses (with side shields). Skin protection Hand protection: Use gloves chemically resistant to this material. Examples of preferred glove barrier materials include: Polyvinyl chloride (PVC or vinyl). Neoprene. Nitrile/butadiene rubber (nitrile or NBR). NOTICE: The selection of a specific glove for a particular application and duration of use in a workplace should also take into account all relevant workplace factors such as, but not limited to: Other chemicals which may be handled, physical requirements (cut/puncture protection, dexterity, thermal protection), potential body reactions to glove materials, as well as the instructions/specifications provided by the glove supplier. Other protection: Use protective clothing chemically resistant to this material. Selection of specific items such as face shield, boots, apron, or full body suit will depend on the task. Page 4 of 12 Product name: DOWSIL™Instantglaze III Assembly Adhesive Issue Date: 03/12/2018 Translucent Respiratory protection: Respiratory protection should be worn when there is a potential to exceed the exposure limit requirements or guidelines. If there are no applicable exposure limit requirements or guidelines, use an approved respirator. When respiratory protection is required, use an approved positive-pressure self-contained breathing apparatus or positive- pressure airline with auxiliary self-contained air supply. 9.
