Dow TPNB Tripropylene Glycol Butyl Ether

Dow TPNB Tripropylene Glycol Butyl Ether is a high-purity, low-volatility glycol ether from Dow’s TPN series. Designed for industrial coatings and cleaning formulations, it offers excellent solvency, slow evaporation rate, and water miscibility. Its branched structure enhances compatibility with resins and reduces odor versus linear ethers. Widely used as an active solvent in water-based paints, inks, and degreasers.

Features Of Dow TPNB Tripropylene Glycol Butyl Ether

  1. Low volatility with high boiling point for extended open time in coatings and inks.

  2. Excellent solvency for resins including acrylics, alkyds, and cellulose esters.

  3. Low water solubility and favorable partitioning behavior in water-reducible systems.

  4. Good compatibility with a broad range of organic solvents and coalescing agents.

  5. Low odor profile compared to traditional glycol ether solvents, supporting improved workplace safety.

Typical Applications Of Dow TPNB Tripropylene Glycol Butyl Ether

  1. Architectural and industrial waterborne coatings as a coalescing aid and solvent carrier.

  2. Flexographic and gravure printing inks for viscosity control and film formation enhancement.

  3. Industrial cleaning formulations requiring moderate polarity and low evaporation rate.

  4. Adhesives and sealants where delayed evaporation improves wetting and bond development.

  5. Specialty agrochemical concentrates for active ingredient solubilization and formulation stability.
