Features Of Kuraray MMB 3-Methoxy-3-Methyl-1-Butanol

  1. Low volatility with high boiling point (172–174 °C), enabling extended open time in coating and ink formulations.

  2. Excellent solvency for cellulose esters, acrylic resins, and nitrocellulose—ideal for high-performance coatings.

  3. Low water miscibility (<5 wt%), supporting phase stability in solvent-borne systems and reducing haze formation.

  4. Favorable evaporation rate profile—slower than ethyl acetate but faster than dibasic esters—enabling balanced film formation.

  5. High purity (>99.0% GC) and low acidity (acid number ≤0.1 mg KOH/g), ensuring formulation stability and minimal resin degradation.

Typical Applications Of Kuraray MMB 3-Methoxy-3-Methyl-1-Butanol

  1. Automotive OEM and refinish coatings requiring controlled flow, leveling, and reduced blush in humid conditions.

  2. Industrial maintenance coatings for metal and wood substrates where recoatability and gloss retention are critical.

  3. Gravure and flexographic printing inks for flexible packaging, especially where low odor and low migration are required.

  4. Architectural solvent-borne enamels and varnishes demanding low VOC compliance without sacrificing application properties.

  5. Adhesive formulations for laminating and specialty tapes requiring balanced solvency and clean evaporation.
