Conditions to Avoid: Contact with oxidizing agents, high heat sources, strong acids, bases
Incompatible Materials: Strong acids or bases, powerful oxidizers, peroxides
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, phenols, other organics
Polymerization: Polymer is fully cured, no hazardous polymerization expected
Acute Toxicity: Low oral and dermal toxicity expected due to polymeric form; unreacted monomer (catechol) is moderately toxic if present
Skin Corrosion/Irritation: Potential skin irritant, especially if abraded
Eye Damage/Irritation: Can cause significant irritation, redness, pain
Respiratory Effects: Dust inhalation may cause irritation to nose, throat, and lungs
Sensitization: Potential for allergic skin reaction based on structure
Long-term Effects: No direct data; chronic inhalation of dust should be avoided
Carcinogenicity: No known carcinogenicity for polymer; see specific data for monomer catechol
Genotoxicity: Not classified
Reproductive Toxicity: No evidence reported for polymer as such
Ecotoxicity: No specific studies; general low mobility in soil, limited bioavailability; monomeric catechol is toxic to aquatic life
Persistence and Degradability: Partially persistent, slowly biodegradable in soil and aquatic environments
Bioaccumulative Potential: Polymer form expected not to bioaccumulate; monomeric catechol can bioaccumulate but likely minimal in polymer
Mobility in Soil: Limited, high adsorption to soil particles expected
Other Harmful Effects: Large spills may alter local pH and oxygen demand
