1. Kuo, Che-shao. Applying Six Sigma on Reducing Stocks of Finished Products â A Case study on a Powder Coating Resin Company.

Degree: Master, EMBA, 2016, NSYSU

Powder Coating Resin industry is increasingly competitive. Besides providing reasonable prices to customers to consolidate market share, how to enhance satisfaction rate on delivery to bring extra value to the client, and how to reduce companyâs Operating Working Captial (OWC) to obtain better financial results, are the two primary goals that enterprises are pursuing. Recently, global recession becomes a normal conditon and production operating rate is often times less than 100%. Under such conditions, how to successfully arrange delivery to meet customersâ needs and well control finished goods inventory becomes very crucial. Therefore, this study aims at identifying approaches for leveraging company's earnings, customer satisfication, and asset of finished Stock. This study is conducted on using data provided by a powder coating resins producing company. Through applying Lean Six Sigma, this study investigates and analyzes the company's historical data, between June, 2014 to December, 2015. After exploring the impacts of finished goods inventory on Operating working capital (OWC) and customer satisfaction rate of delivery, we conclude that product inventory control is an importand and imperative problem faced by the company. Furthermore, through applying DMAIC on the selected case, we identified the key factor that affects inveotry control: Top 10 products inventory quantities. With proper control of the top 10 products invenotry and the safety stock setting at 950 tons, the customer delivery satisfaction rate will reach up to 96%. It is our hope that the adopted framework can serve as a practical decision-making model which allows the Powder Coating Resins producers to optimize its month-end finished goods inventory.

2. Xia, Liuyin. Preparation and formulation of powder coating for application of enamelled wire.

Degree: 2012, University of Western Ontario

Enamelled wire is a conductive wire coated with a very thin layer of insulation, widely used in the field that requires tight coils of wire. The traditional enamelled wire is produced by liquid paint, which consists of resins, solvents, pigments, and additives. Organic solvent takes a relatively high content, normally of 75% to 90% by weight. Many efforts have been made to decrease the percentage of solvent in the insulation paint. On the other hand, increasing the solids content of given enamel results in the viscosity rises significantly, making it harder to flow. Therefore, powder coating technology as an alternative is developed in the production of enamelled wire, not only benefits the environment but also cuts cost of solvent. Mechanical and chemical methods to prepare the fine powder of PVF type enamelled wire coating are reported in this thesis. For gradual solvent evaporation method, kinetics and thermodynamics of the fabrication of microspheres are adopted from reference to predict the operating parameters, such as the solidification time. Factors affecting average particle size and particle size distribution are investigated as well. Phase ratio of emulsion system (DP/CP), emulsion agitation speed, types and dosage of emulsifier, co-solvent and stabilizer are all taken into account. When the DP/CP was 1/15, the resins percentage in DP was 12wt%, the stirring speed was 6000 r/min, 1wt% SDS was used as emulsifier, 1wt% N-octanol and 0.5wt% PVA were employed as co-solvent and stabilizer, the powder of average particle size at around 12 micron can be obtained. Initial PVF enamelled wire coating formulation, as adopted from references of liquid insulation paint, which consists of PVF-E resin, novolac epoxy resin and melamine resin, produced a non-continuous coating finish with many tiny holes formed during curing. This may be attributed to the thermal properties of PVF-E resin or the inappropriate ratio among the different components in the formulation. After that BPA epoxy and its hardener were introduced to the initial formulation to improve the surface quality of coating finish. Then, the paint formulation, powder spraying and curing conditions are optimized. The recommended formulation is with mole ratio of PVF-K, OCFER and melamine resin at 100:375:119, and with proper dosage of degassing and flow agent. The best spraying condition is gun voltage of 30 kV and air stream of 3.0 m/s. When the curing temperature ranged from 215 to 225℃, and the substrates were pre-treated, the number of defects on coating film was reduced.

3. William Wakim. Estudo do fosqueamento de tintas em pó, sistema poliéster/TGIC.

Degree: 2017, University of São Paulo

O presente trabalho propôs-se a estudar o fenômeno de fosqueamento em filmes de tinta em pó feitos a partir de resinas poliésteres sólidas pelo sistema conhecido como Triglicidilisocianutato (TGIC). Este fenômeno é indesejado e ocorre na ocasião de mistura de lotes de tintas produzidos independentemente com resinas poliésteres sólidas que compartilham as mesmas fórmulas, especificações e processo industrial. Amostras de uma tríade de resinas poliéster, que apresenta uma particular relação de fosqueamento, foram estudadas por termogravimetria/ termogravimetria derivada (TG/DTG), calorimetria exploratória diferencial (DSC), espectroscopia de ressonância magnética nuclear de Hidrogênio (1H-RMN), cromatografia de permeação em gel (GPC), análise térmica diferencial (DTA) e espectroscopia de infravermelho com transformada de Fourier (FTIR). A partir da análise minuciosa dos resultados obtidos em cada técnica escolhida, não se notou diferenças significativas que pudessem vir a justificar o fosqueamento indesejado para os lotes estudados. Estas avaliações nos permitiram concluir que o fenômeno não ocorre por contaminação industrial dos materiais e que alguma relação latente de fosqueamento por blenda seca deve ainda ser revelada por estudo subsequente.

The present work endeavored to study the matting phenomenon of powder coatings films made of solid polyester resins through a system known as Triglycidyl isocyanurate (TGIC). This phenomenon is an undesired result and occurs when at the time of blending paint batches produced independently with polyester resins that share the same formula, specifications e industrial process. Samples of a polyester resin triad, that shared a particular matting relation, were studied by thermogravimetry/ thermogravimetry derivative (TG/DTG), differential scanning calorimetry nuclear magnetic resonance (1H-NMR), gel permeation chromatog r(aDpShCy), proton (GPC), differential thermal analysis (DTA) and Fourier transform infrared spectroscopy (FTIR). Through in-depth analyses of all results obtained from each chosen method, no accountable differences, that could justify the undesired matting phenomenon, were noticed. These evaluations paved us the way to conclude that the studied phenomenon was not occurring due to industrial contamination, and that some latent dry blend matting relation is still to be revealed by an ensuing study.
