The adherence plays an important role for studying the binding force between the UV varnish and water-based ink. In order to study the adherence between the UV varnish and water-based ink, the composition that effect on the adherence was studied. The UV varnish samples were prepared by different pre-polymers and different leveling agent. Varnish samples were also prepared by changing amount of leveling agent. Proofs were made by flexo proof press and the PPS value was tested. The adherence of water-based ink on the UV varnish was also tested. The results showed that the type of pre-polymers, the kind of leveling agent and amount have a significant impact on the adherence, the Suitable leveling agent and content should be used.

When common epoxy coatings were applied directly on high temperature (usually about 70°C) steel surface, some defects would occur in coating film, such as bubbles, pinholes, loosen and poor quality flow leveling property, etc. These defects lead to reduction in coating’s adhesion, physical properties and anti-penetrability, shorten service life of coatings greatly, making coating losing their protection function. Main reasons for those defects were analyzed briefly in this paper. In high temperature environment, solvents or other volatile organic compounds (VOC) in coatings will volatilize faster than in normal temperature environment, coating may undergo poor quality flow leveling properties, which couldn’t be fixed by itself. Research and development of a new type epoxy coating were introduced in this paper. Several methods were proposed, including selecting suitable resins, adding high boiling point solvent into coating, using leveling agent and other additives. After these modifications, coating’s construction adaptability was improved and could be applied directly on high temperature steel surface. The scanning electron microscopy (SEM) results show that the coating film prepared in high temperature condition have equivalent fine structure with film prepared in normal condition. The physical properties, anti-penetrability and anti-corrosion were also discussed in this paper

Organosilicone paints were prepared by mixing as-synthesized silicone resin, pigments, fillers and other additives. Through scraping and baking, the thick film coating on the treated aluminum alloy was obtained. The optimum range of P/B (weight ratio of the pigment/binder) was determined to be 0.75:1 by investigating the influence of the P/B on the liquidity and thickness of the coating, indicating that the thickness of the coating reached 500μm. When mica powder, talc powder, nanometer titanium dioxide, sub-micron titanium dioxide, sphere silicon fine powder and lipophilic silica content were 15 wt%, 15wt%, 15wt%, 10wt%, 20wt% and 3 wt % of solid mass of silicone resin, respectively, the coating had good gloss and no holes were occurred on the surface. And there were no bubbles or shrinkage cavities in the obtained coating when the leveling agent S43, defoamer 900 and dispersant 670 content were 0.7 wt%, 0.1wt% and 0.3wt% of the total mass of paint, respectively.

Cationic dye is a special dye for polyacrylonitrile, but it is very difficult in dying through the core. In practice, the price of special leveling agent for polyacrylonitrile fiber is high, and uniform staining is poor. By mixing a number of organic solvents in the dye bath, we can improve the structure of fibers and its deep-dyed. In this paper, we use n-propanol, isopropanol and benzyl alcohol as organic solvent, by adjusting the pH value and the appropriate temperature, and with special depth and leveling agent for dyeing soaping fastness contrast, to find economically viable process conditions.

AbstractThe application of enzymes in the wool dyeing process is an important research goal in order to reduce the environmental impact and costs of this finishing process. The work has focused on the possibility of reducing the temperature of conventional dyeing, using an enzymatic pretreatment with a neutral protease to improve the diffusion of the dye into the fibers. After the identification of the optimal dyeing process, the study goes on transferring the method to an industrial application. For this reason the influence of a leveling agent added to the dyeing bath was considered and further tests with an industrial dyeing recipe were performed. In order to evaluate possible fiber damage, samples treated with enzyme were observed by scanning electron microscopy (SEM) and analyzed by gel electrophoresis (SDS-PAGE). Moreover, the variation of tensile strength and elongation of dyed samples were determined. In addition, color fastness to domestic laundering, perspiration and rubbing were carried out. Finally, color measurements and fiber section analysis were performed. The results show the possibility, thanks to the pretreatment with the investigated enzyme, to obtain a homogeneous and solid dyeing on fibers maintaining good mechanical properties, already working at 85°C instead of 98°C currently used in industry.
