Ethylene glycol tert-butyl ether (ETB), as an environmentally friendly high-boiling solvent, is primarily used in the following fields due to its low toxicity, low odor, and excellent solubility:

I. Coatings and Inks (Core Applications)

1. Aqueous Coating Additives

   • Dispersant and film-forming aid in latex paints, improving low-temperature storage stability and paint film leveling;
   • Enhancing the adhesion and gloss of interior and exterior wall coatings for buildings, as well as automotive primers;
   • Preventing "orange peel" phenomenon in nitrocellulose lacquers, with gloss increased by 2%-6%.

2. Ink Modifiers

   • Improving the rheology of printing inks, enhancing gloss and adhesion in high-speed printing;
   • Acting as a dispersant for special black acrylic paints, reducing carbon black grinding time by over 50%.

II. Cleaning and Surface Treatment

1. Industrial Cleaners

   • Metal degreasers, engine wash detergents, and dry-cleaning solvents, effectively removing grease/lubricating oil;
   • Electronic-grade ETB used for photoresist stripping in liquid crystal panels and chip cleaning solutions.

2. Fiber and Dyeing Auxiliaries

   • Fabric lubricants, modified silicone oil solvents that make textiles soft to the touch and low-irritation;
   • Mineral oil extractants for polyethylene fibers, reducing residue to 0.15%.

III. Chemical Synthesis and Derivative Applications

1. Organic Synthesis Intermediates

   • Synthesis of titanium oxide phthalocyanine dyes (photographic photosensitizers);
   • Preparation of polyoxypropane mono-tert-butyl ether (high-efficiency household cleaners).

2. Functional Additives

   • Fuel additives: improving boiler combustion efficiency and reducing emissions;
   • Epoxy resin coagulants, enhancing the surface properties of high-temperature baking enamels.
