    A review on formulation of waterborne inks

    Waterborne inks for flexography and gravure printing methods, are made from resins, pigments, solvents, waxes, surfactants, crosslinking agents and additives. Resin is the main principle for achieving the functional properties of the printing, in addition to the role of binder for dispersing pigment. A resin is a substance for spreading pigmentation and preventing its aggregation again. It also causes adhesion to substrate. Polymer dendritic network maintains gloss on porous substrates. Polymer

    Thermoset acrylic resins

    Thermal acrylics replace the alkyd / amine stoving enamels in automotive, metal protection and many other industries. While maintaining the optical and chemical properties of acrylic thermoplastic resins, thermoset resins have the advantage of improving chemical properties and hardness. By cleverly choosing the monomers, the amount of them and determining the density of networking, a wide range of properties is achievable.

    Applications of waterborne acrylic resins

    The acrylic polymerization industry, such as the other chemical industries, is driven by global environmental, social and other factors, such as competitive pressure, to produce valuable and qualified products at the lowest possible cost. The variety of acrylic latex chemicals, according to the type and structure of the special blocks, the polymerization process and the complementary operations and particle morphology, meets these requirements. The following, in general, refers to the main uses

    Wetting and dispersing agents in waterborne systems

    Waterborne materials and coatings have different properties compared to conventional solventborne systems. One of these differences is the high temperature required for water evaporation, which leads to slower drying process in these systems than solvent-containing systems, and the high surface tension of water due to the polarity of these molecules. This high surface tension can lead to superficial imperfections and inadequate adhesion of the waterbase coatings applied on the substrate.

    Surfactants used in emulsion polymerization

    Several factors in the process of emulsion polymerization and the characteristics of the final product are important in this way. The selection of environmental friendly and biodegradable raw materials is one of the factors that has been taken into consideration by the manufacturers of emulsifiers with increasing environmental degradation. Meanwhile, the replacement of current surfactants (as one of the most important raw materials in emulsion polymerization) is one of the most prominent issues

    Waterborne roof coatings

    Elastomeric roofing coatings are fluid and formulated products that are applied on a sloped roof surface using spray or roller and can form a continuous protective film on the substrate after evaporation of existing water. These coatings can be used both for repairs to previously waterproofed roof structures and for newly built buildings, especially for the protection of polyurethane foams used for roofs.

    Waterborne toner production technology

    The ink used in EP printers, known as toner, includes a polymer to create a thermal connection between the toner and the substrate, the pigment (generally carbon black) to create color, the charge control agent (such as magnetite, Fe3O4), the additive Flow control (such as fumed silica) and wax to prevent the toner from sticking to the thermal roller.

    Global market of anticorrosion coatings and introduction to recent efforts about waterborne product in Iran

    DTM is a two-in-one covering system including lining and topcoat in a material. Therefore, a DTM coating must simultaneously have the same adhesion and protection against corrosion of a suitable primer and suitable optical properties in different colors. It's easier and faster to use DTM coatings (due to the use of only one product compared to old primer/topcoat systems).
