Description
BDOH solution vinyl resin is a high molecular weight, hydroxyl-functional, partiallyhydrolized vinyl chloride / vinyl acetate resin. It is supplied as a powder.
Applications
BDOH solution vinyl resin can be used for a wide range of coatings applications, including flexible packaging, wood finishes, paper coatings, metal decorative and container coatings, industrial maintenance and marine finishes, and as a binder in magnetic tape.
Advantages
1.Crosslinkable with amino resins or polyisocyanates
patibility with many generic resins including alkyds, and acrylics
3.High Tg imparts good sandabiltiy in vinyl/alkyd/urea wood sealers
4.Resistance to water, alcohols, and aliphatic hydrocarbons
5.Adhesion to vinyl, cellulosic and treated polyester and PE substrates
6.Heat-sealable
7.Tasteless, odorless
8.Conform to regulations for use in food and madcine applications.
