Butyl Glycol CAS 111-76-2 Ethylene Glycol Butyl Ether Solvent for Inks & Resins Ethylene Glycol Monobutyl Ether High Purity

Product Description

Product Overview
Ethylene Glycol Monobutyl Ether, also known as BCS, Anti-Blush Agent, Butyl Cellosolve and 2-Butoxyethanol, CAS No. 111-76-2, molecular formula C6H14O2, molecular weight 118.17. It appears as colorless, transparent and clear liquid without turbidity and suspended impurities, with a mild ether odor. It is a classic high-end glycol ether solvent in the chemical industry. Its core advantage isdual-system miscibility, which is completely soluble in water and miscible with most organic solvents such as alcohols, esters, ketones and hydrocarbons in any proportion, breaking the single dissolution limitation of ordinary solvents. Produced by high-quality raw material catalytic synthesis process, we provide two specifications: industrial grade 99.5% and high-purity premium grade 99.8%. Strictly controlling moisture, acidity, chroma and trace impurities, the product has highly consistent batch quality. Featuring a high boiling point of 171ºC, low volatility, excellent film-forming performance and outstanding anti-blush effect, it perfectly solves industry pain points such as paint film whitening, pinholes, orange peel, sagging and insufficient gloss during coating construction. It is widely used in coatings and inks, industrial cleaning, electronic precision manufacturing, textile printing and dyeing, pesticide and daily chemical, resin synthesis and other fields, serving as a highly versatile multi-functional industrial solvent. With stable and sufficient supply and complete export qualifications, we can provide full sets of customs clearance documents to support global compliant trade.

Ethylene Glycol Monobutyl Ether (BCS, Anti-Blush Agent, CAS 111-76-2) is a saturated aliphatic ethylene glycol monoalkyl ether and a typical water-oil miscible amphiprotic solvent. The molecular structure is fully saturated with single bonds without unsaturated double bonds, ensuring high structural stability. It contains both hydrophilic hydroxyl groups and lipophilic butoxy groups, compatible with both water-based and oil-based formulas. It is a neutral fluid, non-acidic, non-alkaline, non-magnetic, non-oxidative and non-strongly corrosive. With active hydroxyl functional groups, it has slight chemical activity and is not an inert solvent, maintaining stable performance under conventional industrial working conditions.

Detailed Applications
1. High-end Coating Industry (Core Application): It serves as a multi-functional auxiliary and solvent for nitrocellulose paint, polyurethane paint, alkyd paint, epoxy paint, automotive paint, wood paint, industrial baking paint and latex paint. It features excellent anti-blush, anti-fogging, leveling, gloss-enhancing and film-forming effects. It can effectively absorb air moisture, avoid paint film whitening, pinholes, orange peel, shrinkage and cracking under high temperature and high humidity construction conditions, and significantly improve the flatness, gloss and adhesion of paint films.
2. Printing Ink Industry: Suitable for gravure, flexographic, screen, plastic and metal printing inks. It can quickly dissolve ink resins and organic pigments, improve pigment dispersion uniformity, ink leveling and drying performance, presenting delicate printing patterns without wire drawing and dots.
3. Industrial Cleaning Industry: As the core raw material of high-end degreasers, paint removers and metal cleaners, it can efficiently dissolve oil stains, wax, old paint layers and oxidation residues on metal surfaces, widely used for deep degreasing and cleaning of hardware workpieces, mechanical equipment, auto parts and stainless steel products with thorough cleaning and no substrate damage.
4. Electronic Precision Industry: High-purity BCS is suitable for the cleaning of PCB circuit boards, electronic components and precision instruments. It can effectively remove residual flux, micro oil stains and dust impurities with mild volatilization and ultra-low residue, no corrosion to precision electronic parts.
5. Textile Printing & Dyeing Industry: Used as textile dye solvent, printing paste dispersant, chemical fiber oil auxiliary and fiber wetting agent. It improves dye penetration and dispersion, making fabric coloring uniform and full with higher color fastness, and optimizing fabric hand feel and flatness.
6. Pesticide & Daily Chemical Industry: Used as pesticide emulsifier, dispersant and coupling agent to improve the stability of pesticide systems; also applied in the production of household hard surface cleaners, industrial detergents and cleaning auxiliaries with strong compatibility and stable system.
7. Resin Synthesis Industry: Used as reaction solvent and diluent for epoxy resin, polyurethane resin and synthetic adhesives. It improves resin transparency and fluidity, optimizes colloid storage stability and avoids glue turbidity, precipitation and delamination.
Product Advantages
1. Dual Water-Oil Compatibility & Universal Solvency: As an amphiprotic solvent with both hydrophilic and lipophilic properties, it is compatible with all water-based and oil-based formulas. It has strong dissolving power for various resins, pigments, greases and oil stains, replacing multiple single solvents and reducing formula costs.
2. Top-Grade Anti-Blush Performance: A classic industry anti-blush agent, specially solving paint film whitening and fogging defects during high-humidity coating construction, stabilizing paint film status and greatly improving the yield of coating products.
3. High Boiling Point & Low Volatility for Excellent Workability: With a high boiling point of 171ºC and slow uniform volatilization, it extends the open time of coatings, ensures sufficient leveling, avoids sagging, cracking and blooming, and forms flat and high-gloss paint films.
4. Stable Saturated Structure & Consistent Quality: Saturated aliphatic ether structure without unsaturated active bonds, stable chemical properties at room temperature, not easy to oxidize, deteriorate and yellow, with uniform batch color and no delamination or turbidity after long-term storage.
5. High Purity & Low Impurities with Dual Specifications: Two specifications (99.5% industrial grade / 99.8% premium grade) cover all application scenarios. Strict control of moisture, acidity and trace impurities ensures low odor and high transparency for ordinary industrial production and high-end precision manufacturing.
6. Neutral & Safe with Wide Adaptability: Neutral, non-acidic, non-alkaline, non-magnetic, non-oxidative and non-corrosive. It will not corrode substrates, oxidize raw materials or change formula pH system, suitable for multi-material and multi-process production.
