Composition / Information on Ingredients

Main Components: Epoxy Resin Emulsion (CAS 25068-38-6 or equivalent, 40-65%)
Other Components: Water (20-50%), Non-ionic surfactants (1-5%), Emulsifiers, Additives (less than 10%)
Hazardous Ingredients: Bisphenol A Epoxy Resin — Possible presence of reactive diluents and trace stabilizers
Impurities: Industrial byproducts, often trace oxiranes or related epoxide compounds

First Aid Measures

Inhalation: Move affected person to fresh air, seek medical advice if breathing difficulties persist
Skin Contact: Remove contaminated clothing and wash skin with soap and plenty of water, seek medical care for persistent irritation
Eye Contact: Rinse eyes gently for several minutes with water, seek immediate medical attention if irritation remains
Ingestion: Rinse mouth, never induce vomiting, get immediate medical attention if feeling unwell or discomfort persists
Most Important Symptoms: Skin rash, eye redness, irritation, delayed allergic reactions in sensitized individuals

Fire-Fighting Measures

Extinguishing Media: Water spray, dry chemical, foam, CO2
Unsuitable Media: High pressure water jets may spread product or foam
Special Hazards: Fumes including carbon monoxide, carbon dioxide, and irritating organic vapors form under fire conditions
Protective Equipment: Firefighters require SCBA and full protective clothing
Recommendations: Remove containers from area if safe, keep out runoff, cool with water spray

Accidental Release Measures

Personal Protection: Use gloves, goggles, masks to avoid exposure
Spill Response: Contain spillage with absorbents like sand or earth, prevent product from entering drains or watercourses
Clean Up: Scrape up material into containers; decontaminate area with water and detergent
Disposal: Dispose of in compliance with local, state, and federal regulations
Environmental Precautions: Notify authorities if product enters waterways or sewer systems

Handling and Storage

Safe Handling: Handle in well-ventilated areas, minimize skin and eye contact, avoid inhalation of vapors or spray
Storage Conditions: Store in tightly closed, original containers in cool, dry, well-ventilated space away from direct sunlight and sources of ignition
Incompatible Materials: Strong acids, bases, oxidizing agents can trigger hazardous reactions
Other Precautions: Keep away from food and drink, practice good hygiene, clean equipment promptly after use

Exposure Controls and Personal Protection

Occupational Exposure Limits: OSHA/ACGIH standards for epoxy resins are not established; use basic industrial hygiene principles
Engineering Controls: Fractionalization and localized exhaust ventilation reduce inhalation risk
Personal Protection: Gloves (nitrile or neoprene), safety goggles, protective clothing, use of respirator in poorly ventilated areas
Hygiene Measures: Wash hands and exposed skin before eating, drinking, smoking; remove soiled clothing immediately
