The key to responding to the revised Industrial Safety and Health Act is that the established rules are "implemented on-site." At Chuo Resin Chemical, we support the creation of a "Chemical Substance Management Operation Manual" tailored to the realities of your manufacturing site. This manual is not merely a reiteration of the law; it specifically articulates and illustrates the handling procedures for actual products used, such as release agents and diluents, the standards for wearing protective gear, and the response flow for emergencies. As a result, it becomes clear for chemical substance managers and workers "when, where, and what should be done," significantly enhancing the quality of autonomous management. Additionally, the manual can be regularly updated in line with legal revisions and used as educational material for those responsible for managing the use of protective gear. 【Features】 ■ Creation of manuals optimized for your site ■ Concrete procedures that are easy for workers to understand ■ Rapid content updates in accordance with legal revisions ■ Thorough prevention of the "hollowing out" of management systems *Please check the catalog containing actual trouble case examples via the download button.

The mandatory autonomous management of chemical substances has significantly increased the administrative burden on safety and environmental departments as well as manufacturing sites. Wouldn't it be better to outsource this complicated management work to external experts and focus your resources on your core business? At Chuo Resin Chemical, we provide support and carry out a series of tasks, including listing the substances used, organizing SDS, conducting risk assessments, and even building a chemical substance management system. In particular, in environments that use a wide variety of adhesives, cleaning agents, solvents, etc., management tends to become personalized, and there is a risk that compliance with laws and regulations may be neglected due to personnel changes. By utilizing outsourcing, you can establish an objective and standardized management system, thereby strengthening organizational compliance.

"Too high viscosity leaves lumps behind" and "It takes too long to dissolve, making it inefficient." The specialized technology of Chuo Resin Chemical solves these challenges of high-viscosity resins and difficult-to-dissolve materials. Our company is equipped with powerful explosion-proof stirring equipment capable of handling viscosities up to 60,000 mPa·s. Using toluene, MEK, and various solvents, we process materials that are generally considered difficult to dissolve into a uniform solution. A key aspect of quality is the "disassembly and cleaning of the stirring vessel." High-viscosity products tend to leave residues on the walls and blades of the vessel, but our company physically disassembles and cleans it, allowing us to provide high-quality OEM manufacturing without foreign matter contamination, starting from a minimum of 50L. We support from the stage of dissolution consideration, proposing suitable solvent selection, temperature, and stirring conditions. 【Features】 ■ Capable of dissolving high-viscosity materials up to 60,000 mPa·s ■ Uniform processing of difficult-to-dissolve materials with powerful stirring equipment ■ Thorough elimination of residues from high-viscosity products through disassembly cleaning ■ Accepting small orders and dissolution considerations starting from 50L *Please check the document summarizing "9 Checkpoints When Choosing a Contract Dissolution Processing Partner" available for download.
