What is the curing agent for acrylic resins?
What is the characteristic functional groups it depends on your acrylic resin, currently on the market supply is acrylic resin, with isocyanate, pyridine, amino resin, epoxy resin and four with titanium isopropoxide as curing agent.
The curing agent of acrylic resin is actually an initiator, usually peroxide, with benzoyl peroxide, hydrogen peroxide, cumene, tert butyl hydroperoxide, and so on. Many peroxides are white powder, such as benzoyl peroxide, cyclohexanone peroxide and so on.
One component acrylic resin without curing agent, can be air dryHydroxyl containing acrylic resins are often crosslinked with polyurethane resins such as Isocyanates (HDI, TDI)
The difference between acrylic resin and epoxy resin epoxy resin is synthesized from epichlorohydrin and the other containing hydroxyl compounds, molecular intermediate containing epoxy groups and curing agent (amine, anhydride, mercaptan) react to form a three-dimensional cross-linked structure (curing). Acrylic resin is mainly composed of methacrylate. Under the action of initiator (peroxide), the intermediate bond of methyl acrylate is opened and bonded to form a three-dimensional cross-linking structure (curing).
