Product Overview:
The chemical name for ROCRYL 400 monomer called also hydroxyethyl methacrylate.
ROCRYL 400 is a clear, colorless liquid with a pungent, sweet odor.
ROCRYL 400 contains low levelsof a polymerization inhibitoralong with small amounts of methacrylic acid andethylene oxide.
ROCRYL 400 monomer is used in the manufacture of acrylic polymersfor adhesives, printing inks, and coatings for automotive, appliance, and metalapplications.
ROCRYL 400 monomer is sold for industrial use only.
Occupational exposure is possible at a manufacturing facility, during transport,or at facilities using ROCRYL 400 to manufacture other products.
Workplace exposure is minimized through engineering controls and the use of personal protective equipment.
Consumers may contact ROCRYL 400 in trace amounts by using certain productsthat are manufactured from it.
Prolonged or repeated skin contact may result in slight irritation.
Sensitization or an allergic reaction is possible from skin contact.
ROCRYL 400 can be harmful if swallowed or absorbed through theskin.
Inhalation of vapor or mist from heated material during processing may irritate the nose, throat, and lungs.
ROCRYL 400 is practically non-toxicto fish and other aquatic organisms on an acute basis(short-term exposure).
Hydroxyethyl methacrylate (HEMA) is an important vinyl monomer that can be easily polymerized.
The pendant hydroxyl groups make the polymer fully water soluble, whereas lightly crosslinked HEMA forms hydrogels which absorb noticeable amounts of water.
HEMA is frequently copolymerized with other monomers to modify its properties.
Due to ROCRYL 400's low toxicity and hydrophilic character, it has found numerous applications in biomedicine, including contact lenses, drug delivery systems, and dental adhesives.
Another important application of HEMA are isocyanate-free vinyl ester urethane compositions for adhesives, sealants and coatings.
The use of HEMA as a capping agent reduces the toxicity of the prepolymers and increases the low shear viscosity efficiency.
ROCRYL 400 monomer is a reactive chemical that must be stored and handled with care.
ROCRYL 400 is stable under recommended storage conditions.
Inhibitor is added to this product to prevent polymerization.
For the inhibitor to be effective the oxygen concentration in the vapor space must be at least5%.
Avoid contact with acids, bases, oxidizing agents, reducing agents, UV light (ultraviolet light, which is found in sunlight), free-radical initiators, organic peroxides, and mild steel.
Avoid excessive heat.
