2-Hydroxypropyl Methacrylate (2-HPMA)

Gandi Chemical Solutions supplies 2-Hydroxypropyl Methacrylate (2-HPMA) to manufacturers, water treatment plants and industrial processors. Enquiries for 2-Hydroxypropyl Methacrylate are quoted against this listing. Priced by quotation, with a current safety data sheet on every consignment.

2-Hydroxypropyl methacrylate is a reactive monomer that copolymerizes readily with other acrylates, contributing hydroxyl functionality used to crosslink or further modify coating and adhesive resins. It also appears in some dental-composite and specialty polymer formulations. Flammable and an eye/skin irritant — handle with standard monomer-handling precautions and store away from heat and initiators.

Where 2-hydroxypropyl methacrylate is used

• Hydroxy-functional comonomer in thermosetting acrylic resins
• Automotive and industrial two-pack polyurethane coatings
• Dental and biomedical polymer formulation
• Adhesive and sealant resin manufacture
• Crosslinkable emulsion polymers for coatings

Specification and grade

2-Hydroxypropyl methacrylate, formula C₇H₁₂O₃, a clear low-viscosity liquid supplied inhibited with MEHQ. Commercial material is a mixture of the 2-hydroxypropyl and 2-hydroxyisopropyl isomers. The pendant hydroxyl is the working part: it survives the acrylic polymerisation and then reacts with isocyanate or melamine to crosslink the film.

Handling and storage

Causes skin and eye irritation and is a skin sensitiser — methacrylates are well-documented sensitisers and the risk is cumulative. The material polymerises exothermically if the inhibitor is depleted, and MEHQ requires dissolved oxygen to function, so a nitrogen-blanketed drum is the wrong storage: use an air headspace. Store cool, below 25°C, dark, and away from peroxides, amines and metal salts. Never allow a container to sit hot.

Packaging and supply

Packed to your requirement, inhibited, with the inhibitor level stated on the certificate. Tell us your storage temperature and turnover — this is a product where holding stock through a hot season is a real risk rather than a theoretical one.
