CEO Message Solutions for Tomorrow! Since its establishment in 1998, KS Chemical has specialized in manufacturing high-functional resins and paint additives developed based on its independent and differentiated technology. We are supplying outstanding products that are recognized not only in Korea but also in the global market to global companies in more than 20 countries around the world. We are constantly innovating and growing with our customers in line with the trend of the eco-friendly paint market that considers nature. ​ The core of additive products supplied by our company serves as an important role that gives 'value and function' to paints and 'upgrades' their performance. Additives are used in a very small amount in the overall paint formulation, but the additive performance of only a few percent plays a key role in determining the finished paint and painting quality. ​ In the past, paint additives from German and Japanese companies dominated the domestic additive market. KS Chemical has localized additives through technology development to enhance regional and national competitiveness in the material sector and contributes to job creation by hiring local talent as sales increase. ​ Customer needs are becoming more diverse and eco-friendlier as time passes. Depending on the characteristics of the additive industry, which is a small quantity and variety of products, and the characteristics of the industrial group in which customers use paints, customized functions must be satisfied. KS Chemical will continue to do its best to stand at the center of the global market as well as the domestic market by providing the best products according to the customer-first management policy. In addition, we promise to contribute to society by carrying out our mission to contribute to the prosperous human life and nature conservation by producing innovative and sustainable products. ​ ​ 2023.01 ​ CEO Yoo Changjoon, Yoo Eunjung Company Overview 2022 - Awarded the 3 Million Dollar Export Tower ​- ​Started technology project with Ulsan City & Korea Chemical Research Institute - Selected as 'Main Biz' for management innovative corporation 2021 ​- Selected as a star company in Ulsan - Completed development of new silicone products 2020 - Completed development of eco-friendly eco-concept high-functional dispersant by the Ministry of Commerce, Industry and Energy 2018 - Achieved 1 million dollar export ​ - Ulsan City & Chemical Research Institute Technology Cooperation Project 2017 - Selected as a professional technology business based on clean production by the Ministry of Commerce, Industry and Energy - Local specialized industry fostering project 2015 - Awarded Ulsan Chemical Industry Development Award 2012 - INNO-BIZ certification 2011 - Hiblock, Hicure trademark application 2009 - Acquired ISO14001 certification 2006 - Rheoflow trademark application 2004 - Acquired ISO9001 certification 2003 - Acquired CE certification 1998 - Established KS Chemical ​ WHAT DRIVES US SPECIAL?

As a neutral wetting and dispersing agent applied to water-based paints and inks, Rheoflow DW-104 shows excellent wetting and dispersing properties without generating bubbles when manufacturing and using coatings. [Product Features] Applications Used in water-based paints and inks. It is especially recommended for automobile electrodeposition paint, water-based automotive paint, and water-based printing ink. ​ ​ Anti-bubbling properties Water-based wetting and dispersing agents commonly generate a large amount of air bubbles when manufacturing and using coatings. However, Rheoflow DW-104 controls the generation of bubbles in the manufacturing or applying process, so no need to use an additional defoaming agent. ​ Usage It is recommended to use 0.6~1.0% of the total formulation as a wetting agent. As a dispersing agent, it depends on the type and amount of pigment. Product Inquiry ​ Eco-friendly water-base It is used for eco-friendly water-based paints, inks, coatings. Automotive paint It is used for water-based automotive paint, electrodeposition paint and water-based printing ink . ​Strong dispersion effect It is excellent for pigment dispersion, substrate wetting without generation of bubbles. ​Water Type Wetting & Dispersing Agent Chemical Types Features Application ​Product Rheoflow DW-104 100% solid, liquid Rheoflow DW-104BC 50% solid, liquid Alkoxylate Wetting and foam control agent Strong pigment dispersion Perfect defoaming and appropriate anti-foaming effect Electrodeposition coatings Water based coatings Architectural coatings Printing inks 소포제 Rheoflow AF-660 Excellent defoaming properties based on silicone composition/ Outstanding appearance/ Excellent repainting properties [Defoamer] Rheoflow AF-660, a fluorine-modified silicone antifoaming agent, shows excellent defoaming power even with a small amount. It is most suitable for solvent-free, oil-soluble type epoxy and urethane flooring type paint. In particular, it has good defoaming ability even at low temperatures, and hardly causes defects such as craters on the paint surface. In addition, this additive does not cause sedimentation even in sub-zero conditions, and maintains a uniform state. [Product Features] Applications It exhibits excellent defoaming power not only on epoxy and urethane flooring materials but also on enamel paints, and can ultimately be used for all oil-based, solvent-free paints and inks. ​ ​ Additive Cold Storage Stability This additive does not cause precipitation of fluorosilicone even in sub-zero temperature conditions, and does not cause paint defects due to non-uniformity of additives when used. And there is no need for a separate temperature increase condition. Excellent defoaming power at low temperature Compared to general silicone antifoaming agents, it has superior antifoaming lasting power, little change in antifoaming power due to seasonal temperature change, and excellent defoaming power even in low temperature conditions. Usage Excessive use may cause side effects on the surface of the coating film, and sufficient dispersion is required after application.
