Nitocote Nt402 Msds

Write-Up: Nitocote NT402 Safety Data Sheet (SDS/MSDS) Product Overview Nitocote NT402 is a high-performance, solvent-based, surface-tolerant, aliphatic polyurethane coating manufactured by Fosroc (or its regional affiliates). It is primarily used as a topcoat for concrete and steel substrates requiring excellent UV resistance, color retention, and chemical protection. Common applications include bridge parapets, water treatment facilities, industrial floors, and marine environments. Purpose of the SDS The Safety Data Sheet for Nitocote NT402 provides critical information regarding the product’s hazards, composition, safe handling practices, and emergency control measures. It is a legal requirement for employers and users to have access to this document before handling or applying the product. Key Hazard Identification (Based on typical formulation) Nitocote NT402 is classified as a hazardous material. According to GHS classifications, common hazard categories include:

Flammable Liquid (Category 3 or 4): Contains organic solvents with a flash point above 23°C but capable of ignition. Aspiration Hazard: If swallowed, it can enter the lungs and cause chemical pneumonia. Skin Irritation/Cancer/Mutagenicity (specific categories depend on solvent package): Prolonged or repeated exposure may cause dermatitis. Some components may be suspected of causing genetic defects or cancer (e.g., specific aromatic solvents). Specific Target Organ Toxicity (Single Exposure): May cause drowsiness or dizziness from solvent inhalation. Hazardous to the Aquatic Environment: Toxic to aquatic life with long-lasting effects.

Composition / First Ingredient The product is typically a two-part system (Part A = base resin, Part B = isocyanate hardener). The SDS will list substances such as:

Solvent naphtha (petroleum), light aromatic Ethylbenzene or Xylene Hexamethylene diisocyanate (HDI) oligomers (in the hardener – Note: HDI is a sensitizer and potential asthmagen) nitocote nt402 msds

First Aid Measures (Typical excerpt)

Inhalation: Remove victim to fresh air. If breathing is irregular or stopped, administer artificial respiration. Seek immediate medical attention. Skin Contact: Wash thoroughly with soap and water. Remove contaminated clothing. If irritation persists, consult a physician. Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses if present. Continue rinsing for at least 15 minutes. Get medical attention. Ingestion: Do NOT induce vomiting due to aspiration risk. Rinse mouth. Never give anything by mouth to an unconscious person. Transport to hospital.

Fire-Fighting Measures

Suitable extinguishing media: Dry chemical, carbon dioxide (CO2), alcohol-resistant foam. Use water spray to cool exposed containers. Unsuitable: Full water jet (may spread solvent fire). Hazards from combustion: Toxic fumes including carbon monoxide, carbon dioxide, nitrogen oxides, and isocyanate vapors.

Accidental Release Measures (Spills)

Evacuate non-essential personnel. Remove ignition sources. Wear full PPE (nitrile gloves, chemical goggles, respirator with organic vapor cartridges, Tyvek suit). Contain spill using inert absorbent (sand, vermiculite). Collect in approved waste container. Do not wash into drains or waterways. Purpose of the SDS The Safety Data Sheet

Handling and Storage

Handling: Use only in well-ventilated areas (local exhaust ventilation recommended). Ground all equipment to prevent static discharge. Avoid breathing vapors or mist. Do not eat, drink, or smoke during use. Wash hands thoroughly after handling. Storage: Keep in a cool, dry, well-ventilated area away from oxidizers, acids, and ignition sources. Store separately from food and drink. Keep containers tightly closed when not in use.
