The present invention provides coating compositions including: (a) about 75 to about 99.9 weight percent of a crosslinkable film-forming system including one or more crosslinkable film-forming resins and one or more crosslinking materials which is capable of reacting with the film-forming resin to form a crosslinked film; and (b) one or more substantially saturated, predominantly hydrocarbon adhesion promoting agents having an average of more than one pendant or terminal polar group per molecule which are capable of reacting with the crosslinking material, the adhesion promoting agent(s) being present in an amount ranging from about 0.1 to about 25 weight percent on a basis of total resin solids of the coating composition. The coating compositions are useful for directly coating surfaces of thermoplastic and thermosetting plastic substrates, such as TPO and RIM, without the aid of flame or corona pretreatment, or the use of an adhesion promoter. Plastic articles coated with the coating compositions are also disclosed.

Coating composition for plastic substrates

The present invention pertains to durable, chemically-resistant films made from terpolymers. These terpolymers include repeating units of a fluorinated unsaturated monomer, a diester of an unsaturated anhydride with at least one hydroxyl group, and an olefin. The novel films result from curing a coating composition which include: (a) a polymeric component which includes the terpolymers described above, and (b) a crosslinking component. The films of the present invention have many of the excellent physical properties typically associated with those derived from hydroxy-functional fluoropolymers.

A liquid, radiation curable composition is disclosed that includes a reactive diluent to lower initial application viscosity without substantial reduction of cure rate.

Hydroxy functional, unsaturated diesters are disclosed that comprise the esterification reaction products of unsaturated anhydrides with secondary alcohols to form monoesters, followed by oxyalkylation of the monoester with epoxy compounds, whereby a diester is formed with hydroxy functionality. Use of secondary alcohol yields monoesters less prone to disproportionation. The unsaturated diesters may be copolymerized with vinyl monomers to form hydroxy functional copolymers useful in coating applications, wherein they may be included in compositions along with a curing agent that is reactive with hydroxy groups.
