Methacrylates under mild conditions
Makes esters of tertiary alcohols, thioesters and amides that direct esterification cannot.
MAAH
Methacrylic Anhydride Supplier from China
Methacrylic anhydride is a strong methacrylating agent used to make methacrylate esters and thioesters — especially esters of tertiary alcohols — and as a crosslinker in light-curing coatings and polymers. SUNCHEM supplies methacrylic anhydride with a batch COA on every shipment.

제품개요 & 주요 이점
Methacrylic anhydride transfers a methacryloyl group to alcohols, amines and thiols under mild conditions, so it is the reagent of choice for methacrylate esters that are hard to make by direct esterification, such as tertiary-alcohol esters and thioesters. It is also used to methacrylate polymers and biomaterials — for example gelatin methacryloyl (GelMA) and hyaluronic acid for hydrogels — and as a crosslinking monomer in UV- and light-curing coatings.
It is supplied with a polymerization inhibitor; tell us the inhibitor and level your process accepts.
Polymer and hydrogel modification
Adds methacryloyl groups to polymers and biomaterials such as gelatin and hyaluronic acid.
Specified on your terms
We quote against your purity, acid and inhibitor requirements and send the batch COA for each lot.

포장 & 저장
포장
Tell us the pack size you need, from lab bottles to drums; we confirm the packaging with the quotation.
저장
Keep containers tightly closed, cool and dry, away from light. Moisture hydrolyzes it to methacrylic acid; keep the inhibitor active as the SDS describes.

Name the end use
Monomer synthesis, biomaterial or coating: 청정, acid and inhibitor follow from it.
Compare the numbers that matter
청정, free methacrylic acid, inhibitor and color.
Protect the material
Keep it dry and cool; moisture raises the acid content and heat can start polymerization.
Trial, then lock the spec
Run a sample in your own process and keep the approved lot COA as the reference for contract limits.
