Description
[Rohm & Haas] A registered trademark for a clear, colorless, thermoplastic resin acrylic resin. Paraloid B-48N (formerly called Acryloid B-48N in the United States) is a copolymer of methacrylate methyl methacrylate and butyl acrylate. It contains an promoter adhesion promoter that assists bonding to bare and primed metals. Analysis indicates that it also contains a plasticizer, phthalate dibutyl phthalate, that is sometimes concentrated in a residue on the bottom of the container. Paraloid B-48N is used as a clear coating for metals (copper, brass, bronze, and zinc). It produces a tough, flexible coating with excellent durability. Paraloid B-48N is supplied as solid pellets or as 45% solids solution in toluene (Paraloid B-48S).
Synonyms and Related Terms
Acryloid B-48N; Paraloid B48N (sp); Paraloid B-48S; Acryloid B48N (sp); Acryloid B-48N (sp)
Other Properties
Soluble in toluene, xylene, Cellosolve acetate, methyl ethyl ketone, and acetone.
Adding 2% ethanol may reduce cloudiness and stringiness.
