Identification

Product Name: Alkyl Phenolic Resin
SYNONYMS: Modified phenol resin, Alkylated phenol formaldehyde resin
CAS Number: 68987-41-7
Manufacturer: Direct manufacturer or chemical distributor contact details should include company name, full address, emergency phone, and contact email.
Recommended Uses: Used in coating formulations, rubbers, adhesives, and printing inks industries; specialty uses may expand into foundry, friction materials, and paints.

Hazard Identification

Classification: Classified as an irritant based on available data; acute and chronic exposure brings risks of skin, respiratory, and eye irritation; not listed as carcinogenic by IARC, NTP, or OSHA; potential impact from dust inhalation or excessive skin contact.
Hazard Statements: Causes skin and eye irritation; inhaling dust or vapors may trigger respiratory irritation; prolonged exposure can lead to dermatitis.
Pictogram: Exclamation mark (GHS07) for irritant properties.
Precautionary Measures: Wear suitable protection; always use proper ventilation; prevent dust accumulation and inhalation.
Other Hazards: May pose fire hazard as resin dust in air forms explosive mixtures; environmentally persistent if spilled in natural habitats.

Composition / Information on Ingredients

Chemical Composition: Phenol, alkylated (major component 85-95% by weight); formaldehyde (minor residual, <0.5%); residual alkylphenol monomer (<2%); stabilizers and process aids (<1%).
Impurities: Low-molecular-weight oligomers, trace organic solvents if present due to process or storage.
Substance/Mixture: UVCB (unknown or variable composition, complex reaction products or biological materials); trade names and proprietary process may affect proportions.

First Aid Measures

Eye Contact: Flush with clean water for at least 15 minutes; remove contact lenses; keep eyelids open; seek immediate medical attention.
Skin Contact: Remove contaminated clothing and wash skin with soap and water; persistent redness or burning requires medical help.
Inhalation: Move affected person to fresh air; support breathing as needed; get medical help if irritation or symptoms persist.
Ingestion: Rinse mouth with water; do not induce vomiting unless directed by medical personnel; seek prompt medical intervention.
Most Important Symptoms: Burning, redness, coughing, difficulty breathing, headache from dust or vapor exposure.

Fire-Fighting Measures

Suitable Extinguishing Media: Apply foam, dry chemical, carbon dioxide, or water spray. Avoid high-pressure water streams.
Specific Hazards: Thermal decomposition forms CO, CO₂, and toxic phenolic vapors; dust can explode if dispersed in air with spark source.
Protective Equipment: Firefighters use full turnout gear and approved self-contained breathing apparatus.
Advice for Firefighters: Control runoff to prevent environmental damage; evacuate area; monitor for hazardous fumes.

Accidental Release Measures

Personal Precautions: Use proper personal protective equipment (PPE)—gloves, goggles, dust mask or respirator.
Environmental Precautions: Prevent product from entering drains, sewers, rivers, or soil to avoid harmful effects.
Cleanup Methods: Scoop or vacuum up resin powder; avoid generating dust; place in sealed, labeled containers for disposal.
Reference to Other Sections: Always ensure proper ventilation; consult local regulations for waste handling.

Handling and Storage

Precautions for Safe Handling: Avoid skin and eye contact; prevent dust formation; ground equipment to avoid static buildup; train workers on handling hazardous compounds.
Conditions for Safe Storage: Store in cool, dry, well-ventilated area; keep tightly sealed in original or compatible containers; shield from heat, ignition sources, and direct sunlight.
Incompatible Materials: Avoid strong oxidizers, acids, or alkalis; separate from combustion-prone substances.

Exposure Controls and Personal Protection

Engineering Controls: Local exhaust ventilation or fume hoods; maintain air concentrations below occupational exposure limits.
Personal Protective Equipment: Impervious gloves (nitrile, PVC), chemical splash goggles, work uniform or lab coat; for dusts, a NIOSH-approved particulate respirator.
Exposure Limits: No standard limit for alkyl phenolic resin; for residual formaldehyde: ACGIH TLV 0.3 ppm Ceiling; OSHA PEL 0.75 ppm.
Hygiene Measures: Wash hands and skin after contact; change clothes if contaminated; avoid eating/drinking near resin.

Physical and Chemical Properties

Appearance: Amber to brown solid, powder, or flake
Odor: Slight phenolic, sometimes faintly sweet
Odor Threshold: Not available
pH: Not measurable (insoluble in water)
Melting Point/Range: Typically 70–120°C (varies by grade)
Boiling Point/Range: Not determined (decomposes before boiling)
Flash Point: Above 200°C (closed cup, for most grades)
Evaporation Rate: Not applicable
Flammability: Low, but can burn or cause dust explosions
Upper/Lower Flammability or Explosive Limits: Not established
Vapor Pressure: Negligible at 20°C
Vapor Density: Not applicable
Relative Density: 1.05–1.20 (water = 1)

Partition Coefficient (n-octanol/water): Not established
Auto-ignition Temperature: Above 400°C
Decomposition Temperature: Over 280°C
Viscosity: Not applicable; solid at room temperature

Stability and Reactivity

Chemical Stability: Stable at typical ambient temperatures when handled and stored as directed.
Reactivity: No violent reactions under normal use, but dust may ignite with static discharge.
Hazardous Reactions: Contact with strong oxidizers or acids can produce heat or decomposition gases.
Decomposition Products: Carbon monoxide, carbon dioxide, phenol derivatives, formaldehyde vapors (on combustion or decomposition).
Conditions to Avoid: Excessive heat, flame, static discharge, incompatible substances.

Toxicological Information

Acute Toxicity: Low oral and dermal toxicity expected; dust may cause respiratory irritation.
Skin Corrosion/Irritation: Causes mild to moderate irritation due to phenolic groups.
Serious Eye Damage/Irritation: Can cause red, watery, painful eyes, especially if resin dust enters.
Respiratory Sensitization: Not reported, but repeated inhalation of dust may sensitize airways.
Chronic Effects: Repeated exposure can lead to dermatitis or respiratory complaints; not linked to cancer, mutagen, or reproductive hazard at typical workplace exposures.
Other Health Effects: Ingestion or inhalation of large amounts can affect the nervous system and liver.

Ecological Information

Aquatic Toxicity: Low solubility limits acute toxicity; large releases may coat gills of fish and damage microflora.
Persistence and Degradability: Not readily biodegradable; phenolic base resists breakdown in soil and water.
Bioaccumulative Potential: Low for high-molecular resin, higher for unreacted alkylphenol component.
Mobility in Soil: Will not migrate in groundwater; can adhere strongly to sediments.
Other Harmful Effects: May impact aquatic organisms if released in quantity; prevent spillage into environment.

Disposal Considerations

Disposal Methods: Dispose of waste resin as solid industrial waste; incineration preferred if approved facility available.
Special Precautions: Avoid open burning; may require conditioning prior to landfill to prevent dust.
Contaminated Packaging: Use approved containers and label correctly before landfill or incineration.
Regulatory Status: Not regulated as a hazardous waste under US RCRA if free from listed solvents and metals, but local rules may be stricter.

Transport Information

UN Number: Not regulated under UN ADR/RID/IMDG/IATA for most forms.
Proper Shipping Name: Not classified as dangerous goods.
Packing Group: Not applicable
Hazard Classes: None - but dust-forming bulk cargo must follow clean transport recommendations.
Special Precautions: Seal tightly, dry transport; avoid generating dust and static during loading/unloading.
Marine Pollutant: Not expected, but spills near water should be avoided.

Regulatory Information

Chemical Inventory Registration: Registered on US TSCA, EU REACH, Australia AICS, Canada DSL, Japan ENCS, China IECSC.
Workplace Safety: Must follow OSHA or local labor law chemical safety standards.
National/International Regulations: No special restrictions under major chemical regulations unless included alkylphenol monomers exceed trigger levels.
Notification: Large users should alert fire department using resin and dust in substantial quantities.
