Shandong Dayi Chemical Co., Ltd. was founded in 1991 and is an important R&D and production base for silicone products in China. Its product range covers 9 major series and more than 300 varieties, including: The compound hair-care silicone oil developed in 1997 filled a domestic gap, comprehensively improving shampoo performance in enhancing dry and wet combability, gloss, and softness of hair. The aluminum foil paper protective agent developed for the tobacco packaging industry has increased cigarette production efficiency by six times. The spandex oil agent series, especially DY-103 spandex oil agent, has passed the provincial scientific and technological achievement appraisal in Shandong Province and reached the advanced international level of similar products. The MQ silicone resin series features diverse varieties and unique properties, making it an emerging star among silicone resins. These functional new materials are distinctive in China and have been increasingly applied in defoamers, mold release agents, silicone rubber, and pressure-sensitive adhesives. The newly launched dehydrating and moisture-proof agent for synthetic leather slurry, and mold release agent for synthetic leather printing paper, have replaced imports and broken the monopoly of foreign products in the Chinese market. As a new type of highly efficient, non-toxic and environmentally friendly special pesticide additive, silicone pesticide wetting and spreading agents are widely used in agriculture due to their ultra-low surface tension, excellent permeability, wetting, dispersing and spreading properties. Silicone surfactant series products are widely used in paints, inks and coating systems, providing wetting and dispersing effects as well as a smooth feel, while improving film gloss and scratch resistance. The successful development of a series of polyurethane elastomer mold release agents – which are oil-based – ensures smooth demolding with a glossy surface, contributing to the molding of polyurethane elastomer products. Electronic-grade vinyl silicone oil and hydrogen-containing silicone oil for LED electronic potting adhesives have been recognized and praised by LED potting adhesive manufacturers at home and abroad. A large number of high-tech new products such as defoamers, water repellents and sealants for various industries are unique and hold a leading position in China. A series of modifiers for epoxy resins, polyurethanes and other plastics guarantee improved high and low temperature resistance, aging resistance and flexibility of plastic products. Methyl phenyl silicone resin used for high-temperature resistant insulating varnishes and coatings; acrylic-modified silicone resin used for weather-resistant coatings in construction and vehicles; and epoxy-modified silicone resin used for high-temperature anti-corrosion coatings and insulating varnishes for engines, exhaust pipes, chimneys, etc., have all passed novelty searches by provincial-level institutions, with no equivalent products found in China to date.
