SECTION 3: COMPOSITION / INFORMATION ON INGREDIENTS

SECTION 4: FIRST-AID MEASURES

Inhalation

Remove victim to fresh air. Keep resting in a comfortable breathing position. If cough, irritation or difficulty breathing persists, seek medical advice.

Skin contact

Wash contaminated skin with plenty of running water. Take off contaminated clothing. If skin irritation occurs, consult a physician.

Eye contact

Immediately rinse eyes with large amounts of clean water for minimum 15 minutes. Hold eyelids open. Seek medical treatment if irritation continues.

Ingestion

Do NOT induce vomiting. Rinse mouth with water. Never give liquid to unconscious person. Seek medical help if large amount swallowed.

SECTION 5: FIRE-FIGHTING MEASURES

Suitable extinguishing media: Dry chemical powder, carbon dioxide (CO₂), foam.Unsuitable extinguishing media: Direct strong water jet (may spread powder dust).

Hazardous combustion products: Carbon monoxide, carbon dioxide, small amounts of organic fumes.Special protective equipment for firefighters: Self-contained breathing apparatus (SCBA), full protective suit.Additional note: Avoid generation of suspended dust; dust-air mixture may risk dust explosion under high temperature.

SECTION 6: ACCIDENTAL RELEASE MEASURES

Personal precautions: Wear dust mask, safety goggles and nitrile gloves. Avoid dust inhalation. Eliminate all ignition sources.

Methods for containment & cleaning:Collect spilled powder with dry cleaning tools. Avoid generating dust. Place material into sealed container for recovery or disposal. Prevent powder from entering sewer, surface water and soil.

SECTION 7: HANDLING AND STORAGE

Handling

Provide local ventilation to control dust concentration. Avoid dust formation. Prevent electrostatic accumulation. Do not eat, drink or smoke in working area. Wash hands thoroughly after operation.

Storage

Store container tightly sealed. Keep in cool, dry, ventilated warehouse.Storage temperature: 5 ~ 30 ℃. Protect from moisture, direct sunlight and heat sources.Separated storage from strong oxidants, strong acids.Shelf life: 12 months under proper storage.

SECTION 8: EXPOSURE CONTROLS / PERSONAL PROTECTION

Exposure limit values: No established occupational limit for PGMA polymer. Control dust concentration as general inert dust standard.

Engineering controls: Local exhaust ventilation in dust generating working station.

Personal protective equipment (PPE)Respiratory protection: Dust respirator when airborne powder exists.Eye protection: Safety chemical goggles.Skin protection: Nitrile rubber gloves, dust-proof work clothing.

SECTION 9: PHYSICAL AND CHEMICAL PROPERTIES

Appearance: White free-flowing powderOdor: Faint characteristic odor; almost odorlessGlass Transition Temperature (Tg): 42 ~ 48 ℃Thermal Decomposition Temperature: ≥250 ℃Epoxy Equivalent: 280 ~ 360 g/eqSolubility: Soluble in THF, acetone, DMF, MEK; Insoluble in water, aliphatic hydrocarbonsDensity: 1.19 ~ 1.21 g/cm³Combustibility: Non-flammable solidpH: Not applicable (solid polymer)

SECTION 10: STABILITY AND REACTIVITY

Chemical stability: Stable under recommended storage conditions.Conditions to avoid: High temperature, open flame, excessive dust suspension.Incompatible materials: Strong oxidizing agents, strong mineral acids.Hazardous reactions: No known dangerous polymerization. Epoxy groups may slowly react with amine, carboxyl compounds.Hazardous decomposition products: No dangerous decomposition at normal temperature.

SECTION 11: TOXICOLOGICAL INFORMATION

No complete toxicological test data for this high molecular PGMA. Based on polymer structure:

• The high-molecular-weight polymer itself cannot penetrate skin barrier; low toxicity.

• Risk mainly comes from trace residual GMA monomer, which may irritate eyes and respiratory tract.

• Not classified as carcinogen, mutagen or reproductive toxicant.

SECTION 12: ECOLOGICAL INFORMATION

Biodegradability: High molecular polymer is not readily biodegradable.Bioaccumulation: Low bioaccumulation potential.Ecotoxicity: Low toxicity to aquatic organisms. Do not discharge freely into water environment.

SECTION 13: DISPOSAL CONSIDERATIONS

Dispose waste PGMA powder according to local environmental laws.Recommended method: Incineration at authorized chemical waste treatment plant.Do not discard together with domestic garbage. Recycle reusable materials if possible.Contaminated packaging: Clean thoroughly or treat as chemical waste.

SECTION 14: TRANSPORT INFORMATION

UN Number: Not classified as dangerous goods (NON-DG)Proper shipping name: Not dangerous goods for transportTransport class: NonePacking group: NoneRemarks: All transport modes (sea, air, road) not restricted as hazardous chemical. Keep package sealed, prevent moisture and package breakage leading to dust leakage.

SECTION 15: REGULATORY INFORMATION

This product complies with general industrial chemical regulations.Listed status: TSCA inventory; Reach polymer exemption (Mw＞1000).Local regulations should be confirmed for import requirements of destination country.
