摘要:
The present invention relates to low viscosity, ethylenically-unsaturated polyurethanes which are substantially free from isocyanate groups, are liquid at 25° C., have a total content of ethylenically unsaturated groups (calculated as C═C, MW 24) of 1 to 12% by weight and contain the reaction product of A) 4-isocyanatomethyl-1,8-octamethylene diisocyanate (NTI) with B) a hydroxyl component comprising i) 5 to 100 hydroxyl equivalent % of one or more hydroxy functional lactone ester (meth)acrylates having a number average molecular weight of about 200 to 1000, ii) up to 95 hydroxyl equivalent % of a monohydroxy-functional, ethylenically unsaturated compound other than B-i), and iii) up to 20 hydroxyl equivalent % of a saturated hydroxyl compound or an unsaturated hydroxyl compound other than B-i) or B-ii), wherein i) the hydroxyl equivalent %'s of components B-i), B-ii) and B-iii) add up to 100%, based on the total weights of components B-i), B-ii) and B-iii) and ii) the NCO:OH equivalent ratio of component A) to component B) is 1.10:1 to 1:1.10. The present invention also relates to a one-component coating composition containing these ethylenically unsaturated polyurethanes.

The present invention is directed to a composition curable by radiation having a wavelength of 300 nm or more, a method of producing a coated substrate using such composition and the coated product so-produced. More particularly, the composition of the present invention comprises A) from about 1 to about 99% by weight of an unsaturated polymer or oligomer, B) from about 1 to about 99% by weight of an unsaturated epoxy acrylate, C) one or more photoinitiators, and, optionally, D) one or more solvents.
摘要:
The present invention is directed to a non-aqueous composition curable by UV radiation broadly comprising a mixture of two UV curable urethane acrylates. The invention is also directed to a coating process using such composition. One of the urethane acrylates is the reaction product of an isocyanate and a specific OH functional lactone ester (meth)acrylate. The other urethane acrylate is the reaction product of an isocyanate and a specific hydroxy functional (meth)acrylate.
摘要:
A method for printing images on food and packaging for the food. The method includes the step of moving a plurality of food products along a first production line to a first printing station. The method also includes the step of moving a plurality of containers along a second production line to a second printing station. This step is performed during the step of moving the plurality of food products. The method also includes the step of printing a first image on at least one of the food products during the step of moving the plurality of food products. The method also includes the step of selecting a second image from a plurality of differing images in response to the first image. The second image is complementary to the first image. The method also includes the step of printing the second image on one of the containers during the step of moving the plurality of the containers. This step is preformed concurrently with the step of printing the first image. As a result of the concurrent printing of the first and second images, a printed food product and a printed container, respectively, are produced. The second image on the printed container complements the first image printed on the food product.
摘要:
Ultraviolet (UV)-curable polyurethane compositions are provided which are made by reacting an isocyanate with an ultraviolet (UV)-curable polyol that is made by co-polymerizing an alkylene oxide, an unsaturated carboxylic acid or anhydride and a hydroxy functional compound and which has an ultra-low level of unsaturation. The inventive ultraviolet (UV)-curable polyurethane compositions may find use in or as coatings, adhesives, sealants, elastomers and the like.
摘要:
A method of producing an edible food product includes the step of forming a vessel core with a first material having a first level of susceptibility to heating by induction. The method also includes the step of casting an apron of a second material with a second level of susceptibility to heating by induction lower than said first level around at least a first portion the vessel core in an in situ casting process to form a clad cooking vessel having a cooking surface. An uncooked food product is then disposed on the cooking surface of the clad cooking vessel and heated to produce the edible food product by subjecting the vessel core to a magnetic field.

摘要:
A cooking system includes a main wheel having a first surface and a secondary wheel having a second surface. The second surface of the secondary wheel mates with the first surface of the main wheel at a nip to form and set a grain based material disposed between the first and second surfaces. The grain based material may be dried, toasted, baked, puffed, or blistered between first and second surfaces. The method begins by disposing a cooked or uncooked grain based material over the first surface. The second surface, which corresponds to the first surface is applied to the grain based material at the nip to form and set the grain based material between the first and second surfaces. At least one of the first and second surfaces is heated to heat the grain based material disposed between the first and second surfaces to produce a ready-to-eat grain based product.
