1.The role of acrylic resins in photocured inks.Acrylic resin is widely used in the manufacture of photocuring inks because of its unsaturated property and polymerization reaction under the action of ultraviolet light.It and other substances, such as polyether, carbamate, polyester, epoxy resin, modified epoxy resin, poly caprolactam copolymer, can be used as a photocuring ink resin component. 2.T...
Polyurethane is the short form of polyurethane (PU). It is a block polymer formed by addition polymerization. It is a polymer compound with flexible and elastic polyether or polyester as soft segment and rigid and hard carbamate as hard segment. It contains a considerable number of ammonia ester bonds. Waterborne polyurethane has been successfully applied in the textile printing and dyeing industr...
The addition of wetting dispersant has obvious effect on the foam of some water-based ink.For example, polyacrylic acid wetting dispersants foam more than other types of wetting dispersants.Generally speaking, wetting dispersant foam with low dispersion capacity is also less. If diisobutyl sulfonate is based on disate, there is little foam at its content of 0.1-0.25%. The use of thickeners will ma...
Water - based ink is also known as water - based (oil) ink, referred to as ink.Water-based ink is made of water-soluble or water-dispersed polymer resin, colorant, surfactant and other related additives through chemical process and physical processing. Water - based ink containing a small amount of alcohol water as solvent, ink stability.Therefore, it is especially suitable for food, medicine and ...
Printing ink according to the plate type is mainly divided into relief ink, lithographic ink, gravure ink, screen printing ink four categories According to its own characteristics can be divided into two categories of water-based ink and oily ink So what is water - based ink and oil - based ink? What's the difference? Usually see a lot of books, albums and other paper printed matter are used ...
