Milliken’s Additive for Coatings and Plastics Promoted at Plastics Conference 2015
Characterization of Filled Powders for Powder Coating of Paper
Applied Market Information LLC held its first ever Conductive Plastics conference on 29 Jun-1 Jul 2015 in Dusseldorf, Germany. Representatives from Milliken & Company attended the conference and promoted Milliken Chemical's plastics additives. For manufacturers wanting a high-performing static-dissipative additive for coatings and plastics, Milliken Chemical's Zelec electro conductive powders (ECPs) offer remarkable flexibility and durability. Zelec powders work in a variety of coating, packaging, fibre and film products where the dissipation of static charge is important.
The purpose of this study was to evaluate the feasibility of using highly filled powders with 100 parts per weight of calcium carbonate and 10 parts per weight of polymer, acting as binder, as electrostatically applied paper coatings. Such powders prepared by different methods were evaluated as being suitable for electrostatic coating. Powders compacted at elevated temperatures demonstrated cohesion superior to that of calcium carbonate, and at best similar to that of aqueous coatings. Cohesion, porosity and thus absorption properties of compacted powders were affected by the

C OAT I N G S powder preparation method, compaction process, and powder composition. Powders containing semicrystalline polymer turned out to be the most interesting for further testing. Powder coating is an innovative coating process for paper. It could enable cost savings, quality improvements, and new coated paper grades. However, this requires development of highly filled powders, and there have to be easy to use methods supporting the development work. The goal of this study was to test the feasibility of using highly filled powders for paper coatings prior to actual electrostatic deposition and coating trials. Powders with a similar polymer to CaCO3 ratio than in conventional paper coatings were characterized. Particle size and morphology were largely affected by the preparation process. Powder particles were typically granules with internal porosity and evenly distributed polymer. Powders containing semicrystalline polymer as binder turned out to be the most interesting. Charging of the tested designs of powder particles was ranked, and confirmed to fall into a region possible for transfer and attachment. However, formulation, especially the polymer, affected the charging and discharging behaviour of the particles. Some powders had decay times typical for commercial polymeric powders, while some latex containing powders lost their charge only slightly slower than plain CaCO3. Compaction at elevated temperature was essential to decrease porosity and to improve cohesion. Porosity and average pore size were obtained similar to those in conventional paper coatings depending on the compaction process, particle structure, size distribution and composition. At low pressures, the increase in density was mainly due to the inter-granular packing, while at high pressures the compaction was due to the intra-granular deformations. Similar cohesive properties as in conventional paper coatings were achieved after compaction at elevated temperatures, and semicrystalline polymers indicated both interactions with pigment particles and response to heat. However, no unambiguous binder migration favourable for adhesion between powder and paper could be observed. Fast coating processes typical for the paper industry may, therefore, require the use of paper surface pretreatment techniques, and the application of several hot nips in order to optimize coating porosity and to provide suitable conditions for adhesion. There are only few studies about such highly filled powders for electrostatic coating of paper, their composition and key properties. Although the approach has been quite different, some of the results are in line with those obtained from other

A Slower Growth for China A new report by IRL, entitled A Profile of the Chinese Paint Industry, revealed that the growth in the Chinese paint market decreased in 2013. The whole paints and coatings market in China reached 13.1 M tonnes in 2013 and is expected to increase nearly 17.9 M tonnes by 2018, with an average growth rate of 6.5%/y. In 2013, industrial coatings were accounted for 63% of the whole paints and coatings market in China. The largest segment is still the architectural paint segment, which represented 37% of the total demand. Architectural demand was driven by growth in the construction industry. Growth in the protective coatings demand was caused by increase uses in high-speed rail, bridges, containers, roads and nuclear and wind power infrastructure. Growth in the wood coatings market was offset by export stagnation. In 2013, the country's per capita consumption of coatings was just 9.6 kg and the architectural coatings consumption was only 3.6 kg/head. The report also proposed that expenditures will grow by 8.9%/y until 2018. Non-residential buildings represented 38% of the whole construction spending in 2013. It is forecast that the construction spending in the country's Northwest region will rise by almost 10%/y until 2018. The country's Central-East region is projected to contribute 43% of the entire construction expenditures in 2018. A pie graph shows the Chinese paint demand (13.1 M tonnes) in 2013 by auto refinish, architectural, protective, general industrial, industrial wood, powder, marine, auto OEM, and plastic segments.
