Hydroxyethyl acrylate (HEA).
ROCRYL 420 provides hydrophilicity, crosslinking sites and improved adhesion to polymer products.
ROCRYL 420 is recommended for automotive, appliance, & metal coatings as well as printing inks.
ROCRYL 420 is a clear, colorless liquid with a slight acrylic odor.
ROCRYL 420 comprises of a polymerizable acrylate functional group in one end and a reactive hydroxyl group at the other end.
ROCRYL 420 is readily miscible with water and with most organic solvents and has relatively low volatility.
ROCRYL 420 copolymerizes readily with a wide variety of monomers, and the added hydroxyl groups impart properties such as hydrophilicity, improved adhesion to substrates, chemical and scratch resistance, crosslinking sites, low VOCs, and weatherability.
Introduction ROCRYL 420, hydroxyethyl acrylate (HEA) is a clear, colorless liquid with a slight acrylic odor.
ROCRYL 420 comprises of a polymerizable acrylate functional group in one end and a reactive hydroxyl group at the other end.
ROCRYL 420 is readily miscible with water and with most organic solvents and has relatively low volatility.
ROCRYL 420 copolymerizes readily with a wide variety of monomers, and the added hydroxyl groups impart properties such as hydrophilicity, improved adhesion to substrates, chemical and scratch resistance, crosslinking sites, low VOCs, and weatherability.
Applications ROCRYL 420 copolymerizes readily with a wide variety of monomers.
The resulting polymer chains bear pendent hydroxyls that impart the following important properties to the polymer products.
• Hydrophilicity
• Improved adhesion to substrates
• Crosslinking sites, free hydroxy group reacts readily with isocyanate, anhydrides and epoxy resins
• Corrosion, fogging, and abrasion resistance, as well as contribute to low odor, color, and volatility
ROCRYL 420 monomer is used in the manufacture of acrylic polyols, caprolactone monomers, printing plates, and finish coatings for motor vehicles, appliances, and metals.
Other end uses of ROCRYL 420 include adhesives, sealants, and binders.
