Lubestine filler for use in paint and ink formulations. » View All the Commercially Available Polyurethane Resins Used in Coatings! When exposed to water, milk, and UV light, ink surfaces showed similar behavior in the atomic force microscope, Fourier‐transform infrared spectroscopy, and UV–vis analysis. Innovative polyurethane ink binder solutions for printing inks. » View All Commercially Available Resins Suitable for Solvent-based Inks Are obtained by reacting MDI, HDI or TDI with polyether or polyester polyols that are linear branched with an isocyanate content below 20%. Pendulum hardness of this formulation applied immediately after mixing and 2 hours after mixing is shown in Figures 1 and 2. HI-THANE™ polyurethane ink binders Learn more. • Polymers in solution, which improve pigment wetting and make re-solubilising. Colour and opacifying properties lead to use as a partial replacement for TiO2 Page 1 Product List Coatings, Inks and Adhesives SONGWON – Long-standing expertise in printing ink technology for flexible packaging. US Polymers-Accurez and its Reze-Thane ™ product line, which includes Reze-Lastic™ and Reze-Meric™ formulations, are recognized throughout the ink industry as top-performing products in their categories. The newer grades are up to 40% more efficient than competitive associative thickeners, offering excellent cost saving potential ( Figure 1 ). The VESTOWAX® product range covers a series of synthetic waxes (polyethylene, Fischer-Tropsch, EVA copolymer and modified polypropylene waxes) with a broad spectrum of applications. All just mentioned non-reactive systems have in common that isocyanates do not react during application. Aliphatic systems are utilized where non-yellowing is a must, which is the case among other for PVC floor tiles and continuous flooring. Benzophenone is a typical photoinitiator which produces free radicals when absorbing UV and then initiates the crosslinking through the acrylate groups.

Formulation and Materials for Inkjet Inks: Pigments for Inkjet Applications (A Shakhnovich & J Belmont) Formulation and Properties of Waterborne Inkjet Inks (C Schmid) Solvent-Based Inkjet Inks (J Samuel & P Edwards) Formulating UV Curable Inkjet Inks (S E Edison) Raw Materials for UV Curable Inks (I Hatchison) Inks for laminations have to withstand the lamination process and deliver the bond strength necessary for the respective application. Composition of Inks: The colorant can either be pigments, or dyestuffs. Water-Based PUD. Based on these first promising results from phase 1, PrintCYC members strived for further improvement by testing alternative ink formulations for printing on BOPP and Low Density Polyethylene (LDPE) films. Aromatic grades are used in wood, paper, plastic and ink coats, while. The properties of flexographic inks obtained by the partial replacement of nitrocellulose (NC) resin with different amounts of polyurethane (PU) resins were evaluated for the statistical planning of mixtures to develop an optimum ink formulation.

Amine-terminated chain extenders, such as diethyl toluene diamine (DETDA) or isophorone diamine (IPDA). Each resin type shown can be combined with others to increase the overall performance of the inks, for example - nitrocellulose is often combined with polyurethane or polyamide resins. Isocyanates - may be aromatic or aliphatic - all contain one active hydrogen and contain a blocking agent most of the time caprolactam. US 2K Polyurethane Dispersion Exhibiting Enhanced Adhesion using HALOX® 550 WF Free Product Samples Click Here Worldwide Distribution Find Distributors Got a Aliphatic isocyanates react more slowly and result into softer coatings than those made of aromatic isocyanates.
