NitoCote NT-402 MSDS

Introduction

NitoCote NT-402 is a high-performance, water-based coating product manufactured by NitoCote, a leading company in the field of coatings and linings. The product is designed to provide exceptional corrosion protection and chemical resistance for various industrial applications.

Product Composition

The NitoCote NT-402 coating is a two-component, water-based epoxy system consisting of:

• Component A (Resin): A water-based epoxy resin
• Component B (Hardener): A water-based amine hardener

MSDS Sections

Here are the key sections of the MSDS for NitoCote NT-402:

Section 11: Toxicological Information

The MSDS confirms that Nitocote NT402 is not a chronic health hazard in normal handling, but acute exposure is dangerous.

• Acute Toxicity (Oral): LD50 > 2000 mg/kg (rat) – relatively low toxicity if swallowed, but aspiration is the real risk.
• Skin Corrosion: Mild irritant (defatting).
• Eye Irritation: Moderate (causes stinging).
• Carcinogenicity: Ethylbenzene is classified as Group 2B (possibly carcinogenic to humans) by IARC. However, the concentration in the formulation is below major thresholds. Still, minimize vapor exposure.
• Reproductive Toxicity: Not classified, but high doses of xylene have shown effects in animal studies.

Section 8: Exposure Controls / Personal Protective Equipment (PPE)

This is the section most frequently consulted by safety officers.

| Exposure Route | Control Measure | Recommended PPE | | :--- | :--- | :--- | | Inhalation | Local exhaust ventilation (LEV) | Half-face or full-face respirator with Organic Vapor (OV) cartridges (e.g., NIOSH approved 6001). | | Skin (Hands) | Chemical barrier | Nitrile gloves (0.4mm thickness, >480 min breakthrough time). Do not use latex or neoprene – they degrade quickly with aromatics. | | Skin (Body) | Avoid splashes | Tyvek or chemical-resistant apron. | | Eyes | Splash guard | Chemical splash goggles (not just safety glasses). | | Footwear | Spill resistance | Rubber boots with steel toe (leather absorbs solvent). |

Occupational Exposure Limits (OELs): For Xylene, the typical 8-hour TWA (Time Weighted Average) is 100 ppm (435 mg/m³) ACGIH. The MSDS will state that users should stay below these limits. nitocote nt402 msds

1. Introduction

Nitocote NT402 is a high-performance, two-part, water-based epoxy coating manufactured by Fosroc. It is designed for the protection and beautification of concrete and masonry surfaces (e.g., bund walls, secondary containment areas, concrete floors).

The MSDS (Material Safety Data Sheet) – now commonly referred to as SDS (Safety Data Sheet) under GHS – is the critical legal document that governs how this material is handled, stored, and used. This feature breaks down the key sections of the Nitocote NT402 MSDS.

3. Hazard Identification (GHS Classification)

The MSDS typically classifies Nitocote NT402 as a Hazardous Chemical (depending on regional regulations). Key hazards include:

| Hazard Class | Part A (Resin) | Part B (Hardener) | |--------------|----------------|--------------------| | Skin Corrosion/Irritation | Category 2 | Category 1B/2 | | Eye Damage/Irritation | Category 2A | Category 1 (Serious) | | Skin Sensitization | May cause allergic reaction | Yes – Known sensitizer | | Aquatic Toxicity | Chronic 2/3 | Chronic 2/3 |

Key Signal Word: DANGER (primarily due to Part B) NitoCote NT-402 MSDS Introduction NitoCote NT-402 is a

Hazard Statements (examples):

• H315 – Causes skin irritation
• H317 – May cause an allergic skin reaction
• H318 – Causes serious eye damage (Part B)
• H411 – Toxic to aquatic life with long-lasting effects

Firefighting measures

• Extinguishing media: Foam, dry chemical, CO2, or water spray to cool containers.
• Hazards: Combustion can produce CO, CO2, and toxic fumes (oxides of nitrogen, etc.).
• Protection: Firefighters should use self-contained breathing apparatus and full protective gear.

Section 5: Firefighting Measures

Given the flammable nature of the solvent carrier, fire is a serious risk.

• Flash Point: Approximately 25°C – 30°C (closed cup).
• Auto-ignition Temperature: >350°C.
• Explosive Limits: Lower explosive limit (LEL) ~1.0%; Upper explosive limit (UEL) ~7.0%.
• Suitable Extinguishing Media: Carbon dioxide (CO2), dry chemical powder, alcohol-resistant foam. Do not use water jet as it spreads the burning solvent.
• Specific Hazards: Burning produces toxic fumes including carbon monoxide (CO) and nitrogen oxides (NOx).
• Protective Equipment for Firefighters: Full self-contained breathing apparatus (SCBA) and full protective gear.

Section 1: What is Nitocote NT402? (Product Identification)

Before analyzing the MSDS, it is essential to understand the product itself. According to the technical data sheet and the MSDS:

• Product Name: Nitocote NT402
• Manufacturer: Fosroc International (various regional subsidiaries)
• Type: UV-resistant, elastomeric, solvent-based acrylic coating.
• Appearance: Colored liquid (typically white, grey, or custom tints).
• Odor: Strong aromatic solvent odor (e.g., Xylene, Toluene).
• Primary Use: Providing a decorative, breathable, yet waterproof barrier for concrete. It protects reinforcing steel from carbonation and chlorides.

The MSDS is not a user manual for application, but a legal document outlining hazards. The primary risks associated with Nitocote NT402 stem from its solvent content, not the acrylic resin itself.
