2-HYDROXY ETHYL ACRYLATE CAS:818-61-1

2-HYDROXY ETHYL ACRYLATE CAS:818-61-1, chemically known as 2-hydroxyethyl acrylate, is a multifunctional monomer containing both a hydroxyl group and an acrylate double bond. Its molecular structure possesses both a hydrophilic hydroxyl group (-OH) and a highly reactive carbon-carbon double bond (C=C). It exhibits the polymerization characteristics of acrylate compounds and can also undergo esterification and etherification reactions through the hydroxyl group. It is widely used in polymer synthesis, coatings, adhesives, and fine chemicals, making it an important intermediate in the fine chemical industry.

1. Coatings Industry: Core Monomer for Environmentally Friendly Coatings

With increasingly stringent global environmental regulations (such as the EU REACH and China's VOC limit standards), environmentally friendly coatings such as water-based coatings and UV-curing coatings are gradually replacing traditional solvent-based coatings. HEA, as a key functional monomer, plays a core role in these coatings by providing "film formation modification + crosslinking enhancement."

2. Adhesives and Sealants: Core Raw Materials for High-Performance Bonding

By adjusting the hydrophilic/hydrophobic balance and crosslinking density of polymers, HEA significantly improves the bonding strength, weather resistance, and environmental friendliness of adhesives, making it a key raw material for high-end adhesives such as water-based and UV-curing adhesives.

3. Resin Synthesis: The Core of Functional Polymer Modification

HEA, as a copolymerization or modification monomer, can precisely control the structure and properties of resins, and is an important raw material for functional resins such as acrylic resins, polyurethane resins, and epoxy resins.

4. Fine Chemicals and Electronic Materials: Key Intermediates for High-End Functional Products

The hydroxyl group and double bond of HEA can be further derivatized to produce a variety of functional compounds, which have unique applications in high-end fields such as electronic materials, surfactants, and superabsorbent resins.

5. Pharmaceutical and Personal Care Fields: Functional Excipients and Raw Materials

Pharmaceutical-grade HEA complies with international pharmacopoeia standards such as USP and EP, and its low impurity and low toxicity characteristics have led to its expanding applications in the pharmaceutical and personal care industries.

6. Other High-End Applications

- Metal Processing: As a formulation component of environmentally friendly metal cleaning agents, it is used in conjunction with surfactants and corrosion inhibitors. Utilizing its excellent solubility and compatibility with metal surfaces, it efficiently removes oil stains, cutting fluid residues, polishing wax, and other impurities from metal surfaces. It is especially suitable for cleaning precision metal parts (such as electronic component pins, automotive precision bearings, and medical device metal parts). After cleaning, it evaporates easily with no residue, does not damage metal plating (such as zinc or chromium plating) and insulation layers, and dries quickly (3-5 minutes at room temperature), improving the efficiency of subsequent processing (electroplating, assembly).

- Aerosol Propellant Auxiliary Component: As a solvent and dispersant for environmentally friendly aerosols (such as water-based paints, cleaning agent aerosols, and mold release agent aerosols), it works synergistically with propellants (such as propane and butane) to ensure uniform dispersion of the aerosol contents (pigments, cleaning components), preventing stratification and sedimentation. After spraying, it forms a uniform film with good coverage, and its high flash point (99℃) makes it non-flammable, improving the safety of aerosol products and meeting environmental and safety standards. It is suitable for sensitive environments such as indoors and areas near food contact.

- Petroleum Processing: As a modifying component for petroleum dewaxing solvents, it is used in combination with traditional dewaxing solvents (such as ketones and aromatics). Its polar groups disrupt the crystalline structure of waxy components (paraffin wax, microcrystalline wax) in petroleum, lowering the wax crystallization temperature and improving dewaxing efficiency. At the same time, it improves the low-temperature fluidity of petroleum products (such as diesel fuel and lubricating oil) (pour point can be reduced by 10-20℃), meeting the requirements for use in extremely cold regions, without affecting other properties of petroleum products (such as viscosity and flash point).
