818-61-1 Usage
Description
2-Hydroxyethyl acrylate (HEA) forms homopolymers and copolymers. HEA is used mainly either as a co-monomer in the manufacture of polymers or as a chemical reactant in the manufacture of chemical intermediates. In the manufacture of polymers, HEA can be co-polymerized with acrylic acid, acrylates, methacrylates, vinyl acetate, vinyl chloride, vinylidene chloride, styrene, butadiene, and the like. Co-reactants with HEA include aromatic and aliphatic isocyanates, anhydrides, and epoxides. The polymers and chemical intermediates made with HEA find applications in automotive top coatings, architectural coatings, photocure resins, and adhesives. Globally about half of the HEA produced is used in the production of acrylic enamels for the automotive industry, where a clear topcoat is applied to a pigmented base coat to increase corrosion protection and durability.
Chemical Properties
Hydroxyethyl acrylate is a clear colorless liquid. miscible with water, soluble in general organic solvents. The commodity generally contains 400ppm of hydroquinone methylether, a polymerization inhibitor. Hydroxyethyl acrylate is a difunctional acrylate monomer with the characteristic high reactivity. Hydroxyethyl acrylate is used in a crylics for coatings, adhesives and UV reacitve oligomers. It can be used for crosslinking with isocyantes or melamines.
Uses

Potential Exposure
2-Hydroxyethyl acrylate is contained in Lowicryl 4KM and K11M resins. It caused contact dermatitis in workers embedding media for electron microscopy. It may also be contained in ultraviolet-curable nail gel used for photobonded sculptured nails.
Check Digit Verification of cas no
The CAS Registry Mumber 818-61-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,1 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 818-61:
(5*8)+(4*1)+(3*8)+(2*6)+(1*1)=81
81 % 10 = 1
So 818-61-1 is a valid CAS Registry Number.
