Normal Butyl Acetate Urethane Grade
Formula: C₆H₁₂O₂

Butyl Acetate

Normal Butyl Acetate (NBA)

Normal Butyl Acetate is a clear, colorless liquid ester with a characteristic pleasant "fruity" odor (resembling bananas). It is the most important medium-boiling solvent in the paint industry. Ruvon supplies Urethane Grade NBA, which has ultra-low moisture content, making it safe for use in Polyurethane (PU) hardeners and coatings.

CAS Number 123-86-4
Purity 99.5% Min
Moisture Max 0.05%

Product Overview

Butyl Acetate is formed by the esterification of Butanol and Acetic Acid. It is highly valued for its excellent solvency for Nitrocellulose, Polymers, Resins, and Oils. It creates a smooth finish in lacquers, preventing blushing (whitening due to moisture).

  • Medium Volatility: It doesn't evaporate too fast (like Acetone) or too slow (like Butyl Cellosolve), providing the perfect "flow and leveling" for paints.
  • Non-Hygroscopic: Unlike alcohols, esters absorb very little water from the air, making them stable in high-humidity environments.
  • Aroma: Its pleasant banana scent makes it a popular solvent for nail polish and removers.

The Benchmark: Why RER = 1.0?

The Gold Standard of Volatility

In the paint industry, Butyl Acetate is the "Reference Point". Its Relative Evaporation Rate (RER) is set at exactly 1.0.

  • Fast Solvents (> 1.0): Solvents like Acetone (RER 5.6) evaporate faster. They are used for quick drying but can cause "orange peel" texture.
  • Slow Solvents (< 1.0): Solvents like Butyl Glycol (RER 0.06) evaporate slower. They keep the paint wet longer for brushing.
  • The Balance: NBA (1.0) is the perfect middle ground. It allows paint to level out smoothly before locking in place.

Industrial Applications

Automotive Refinish

The primary solvent for car basecoats and clearcoats. Ensures high gloss and smooth finish.

Wood Coatings

Used in Nitrocellulose (NC) lacquers and PU wood sealers for furniture.

Nail Care

The main ingredient in nail polish and nail polish removers (better smell than acetone).

Pharmaceuticals

Extraction solvent for processing antibiotics like Penicillin.

Leather Industry

Used in leather dressings and finishes to dissolve coatings without damaging the hide.

Food Flavoring

Used in synthetic fruit flavorings (banana, pear, pineapple) for candies and ice cream.

Packaging Options

Safety & Handling Protocols

Flammable Liquid

Butyl Acetate is a Class 3 Flammable Liquid (Flash Point 22°C).

  • No Sparks: Use non-sparking tools and grounded equipment. Store away from heat sources.
  • Ventilation: Vapors are heavier than air. Ensure good ventilation at floor level.
  • PPE: Wear solvent-resistant gloves and goggles. Prolonged inhalation can cause dizziness.
