High Purity Diethylene Glycol Butyl Ether Acetate Dbea CAS 124-17-4 Slow Evaporation High Boiling Solvent for Automotive Baking Paint & Screen Printing Ink

Product Description

1. Product Overview

Diethylene Glycol Butyl Ether Acetate, abbreviated as DBEA, fixed CAS No.124-17-4, molecular formula C10H20O5, is a colorless transparent oily glycol ether ester solvent synthesized via esterification of diethylene glycol monobutyl ether and glacial acetic acid. It features ultra-low volatility, high boiling point (246ºC), strong dissolving capacity for various resins, mild odor and slow evaporation speed.

As a multi-functional high-boiling retarder solvent, DBEA is widely applied in automotive baking paint, screen printing ink, PCB electronic cleaning, photoresist, water-based wood coating, coil coating, PU adhesive and photosensitive chemical industries.

Our factory owns complete esterification and rectification production lines, with stable raw material supply chain. We produce three standard grades: industrial grade ≥99.0%, high purity grade ≥99.5%, electronic grade ≥99.8%. Each batch is inspected by gas chromatography to guarantee stable purity, low chroma and low free alcohol impurity. As direct Chinese manufacturer without middlemen, we support small trial orders, bulk IBC tank and full container shipment with competitive FOB price and complete export documents.

3. Full-Scenario Industrial Application Introduction

3.1 Automotive & Household Appliance Baking Coatings

DBEA is core slow-evaporation coalescing solvent for high-temperature baking varnish of cars, home appliances, aluminum coil and metal hardware. It fully dissolves acrylic, polyester, epoxy and amino resin, eliminates sagging, orange peel and brush marks during construction, greatly improve coating surface gloss, hardness, weather resistance and anti-scratch performance. Its slow volatilization avoids pinholes and blisters under high-temperature baking condition.

3.2 Screen, Gravure & Flexo Printing Ink

As anti-blocking retarder solvent for all kinds of printing ink. It delays surface drying of ink effectively to prevent screen mesh clogging, improve printing pattern definition and color uniformity, suitable for plastic film printing, circuit board marking ink, glass printing glaze and packaging gravure ink formulation.

3.3 PCB Electronic Manufacturing & Optical Coating

High purity & electronic grade DBEA serves as cleaning solvent for PCB circuit board, removing residual photoresist, solder paste and surface oil stain without corroding copper foil. It is also used as diluent for LCD optical coating and photosensitive photoresist intermediate, low ion residue ensures no damage to precision electronic components.

3.4 Water-based Furniture Wood Coatings

Environment-friendly low-odor coalescent auxiliary for waterborne PU wood paint, water-based acrylic furniture coating and water-based floor paint. It promotes complete resin film formation at room temperature, reduce film forming temperature, improve coating flexibility and water resistance, low VOC meets international environmental protection standards.

3.5 Adhesive & Leather Coating Industry

Excellent diluent for single-component and two-component water-based polyurethane adhesive, solvent-based laminating adhesive and leather surface finishing agent. It balances adhesive viscosity, prolong open time and enhance bonding strength between different substrates.

3.6 Fine Chemical Synthesis Intermediate

Raw material for plasticizer, photosensitive chemical, metal surface degreasing cleaner and printing auxiliary synthesis, widely used in fine chemical processing factories.
