Packaging and shipping
Triethylene glycol monobutyl ether also known as Butyl Triglycol, is an important member of the ethylene glycol ether family. Compared with 2-ethylolpropane butyl ether (butyl carbomer), its molecular chain is longer, thus possessing a higher boiling point, lower volatility, and stronger hydrophobicity. It is an ideal choice for applications that require long-lasting effects, stable performance at high temperatures, and deep penetration.
Product Description
Anhui Eapearl Chemical Co., Ltd., as a professional manufacturer of alcohol ether solvents and specialty chemicals in China, is committed to providing customers with high-quality and high-performance chemical raw materials. Currently, we are steadily supplying butyl triglycol (butyl triglycol), a type of ultra-high boiling point, low volatility, and strong dissolving power multi-functional alcohol ether solvent, to the market. With its unique molecular structure (three ether link units and one hydroxyl group), this product demonstrates outstanding value in numerous industrial fields with strict requirements for solvent performance.
Butyl triglycol, also known as butyl triglycol, is an important member of the ethylene glycol ether family. Compared with butyl carbolic acid glycol (butyl diacetyl glycol), its molecular chain is longer, thus having a higher boiling point, lower volatility, and stronger hydrophobicity. It is an ideal choice for those seeking long-lasting effects, stable high-temperature processes, and deep penetration applications.
High boiling point and extremely low volatility: The boiling point is far beyond that of conventional solvents (>260°C), and the evaporation rate is extremely slow, providing an extremely long leveling time for the coating and ensuring that cleaning agents, processing fluids, etc. maintain stable performance during high-temperature or long-duration processes.
Excellent dissolution and coupling ability: It has excellent dissolution power for resins, oils, dyes, nitrocellulose, etc., and can effectively couple the aqueous phase with the oil phase, improving the compatibility of complex formulations.
Outstanding surface activity and wetting ability: It can effectively reduce surface tension, enhance the spreading and penetration ability of the formulation on various substrates, and is particularly suitable for cleaning agents and textile treatment agents.
Good chemical stability and safety: It is stable at normal temperature and pressure and has good compatibility with many chemicals. Its relatively low acute toxicity (rat oral LD50: 5300 mg/kg) makes it have good safety for use under standard operations.
Main application fields
High-end coatings and inks: As an ultra-high boiling point solvent and film-forming aid, it is used in industrial baking paints, automotive paints, ship coatings, and high-end inks, significantly improving leveling, preventing scuffing, enhancing gloss and adhesion, especially suitable for systems requiring high-temperature baking or slow drying.
Efficient industrial cleaning and metal processing: It is a powerful solvent for heavy oil stains, paint, and soldering agent residues, used for metal degreasing, precise cleaning of electronic components (such as integrated circuits), and industrial equipment maintenance cleaning. Its long-lasting nature is suitable for scenarios such as shutdown maintenance and overhaul.
Agricultural chemicals: Used as an efficient dispersant and solvent for pesticides, improving the spread and adhesion of the liquid formulation on leaves, enhancing the efficacy of the pesticide.
Polymer processing and synthesis: As a resin plasticizer and processing aid, it is used to improve the processing fluidity and flexibility of plastics and rubber; at the same time, it can be used as a reaction intermediate or solvent in organic synthesis.
Daily chemical products and textiles: Used for preparing mild and non-irritating household liquid detergents; in the textile industry, it is used as a fiber wetting agent and dye carrier.
Emerging and special fields: In electronic chemicals, it is used for PCB process cleaning; in the synthesis of nanomaterials (such as superparamagnetic iron oxide nanoparticles), it is used as a reaction solvent; it can also be used in special applications such as CO₂ capture.
