Abstract
A method of applying a curable composition. The method includes providing a curable composition comprising about 10 to about 60 weight percent of one or more epoxy resins; about 20 to about 80 weight percent of one or more resins selected from polyester resins, ethyl vinyl acetate resins, thermoplastic resins, and acrylate resins; up to about 30 weight percent of one or more hydroxyl-containing compounds; and an initiator selected from a photoinitiator, a thermal initiator, and combinations thereof. The method further includes initiating cure of the curable composition.
Claims25
A method of applying a curable composition comprising:
- a) providing a curable composition comprising:
- (i) about 10 to about 60 weight percent of one or more epoxy resins;
- (ii) about 20 to about 80 weight percent of one or more resins selected from polyester resins, ethyl vinyl acetate resins, thermoplastic resins, and acrylate resins;
- (iii) up to about 30 weight percent of one or more hydroxyl-containing compounds;
- and
- (iv) an initiator selected from a photoinitiator, a thermal initiator, and a combination thereof;
- b) initiating cure of the curable composition;
- c) optionally, providing a first dwell time of up to 120 minutes, wherein the curable composition is at least partially cured and remains tacky;
- d) applying the curable composition to at least one nozzle having an orifice;
- e) providing a second dwell time of up to 7 days, wherein the curable composition becomes substantially tack free.
A method of applying a curable composition comprising:
- a) providing a curable composition comprising:
- (i) about 10 to about 60 weight percent of one or more epoxy resins;
- (ii) about 20 to about 80 weight percent of one or more resins selected from polyester resins, ethyl vinyl acetate resins, thermoplastic resins, and acrylate resins;
- (iii) up to about 30 weight percent of one or more hydroxyl-containing compounds;
- and
- (iv) an initiator selected from a photoinitiator, a thermal initiator, and combinations thereof;
- b) applying the curable composition to at least one nozzle having an orifice;
- c) initiating cure of the curable composition;
- d), providing a dwell time of up to 7 days, wherein the curable composition becomes substantially tack free.
An article comprising:
- an inkjet cartridge;
- and
- a layer of curable composition comprising a first surface and a second surface opposite the first surface, wherein the first surface is applied to a surface of the inkjet cartridge, the radiation-curable composition comprising:
- (i) about 10 to about 60 weight percent of one or more epoxy resins;
- (ii) about 20 to about 80 weight percent of one or more resins selected from polyester resins, ethyl vinyl acetate resins, and acrylate resins;
- and
- (iii) up to about 30 weight percent of one or more hydroxyl-containing compounds.
