About us


Dayi insists on the high-tech development road, marches forward hand in hand with people from all walks on the road of science and civilization.

1.The composite hair silicon oil developed earlier filled the domestic gap. The quality of shampoo can be

improved comprehensively in improving wet and dry combing of the hair, adding luster and softness of

hair. The market share in the shampoo industry is up to 20%.

2.Aluminum-foil paper protective agent developed for tobacco packaging industry can increase the

cigarette production efficiency 6 times. 30% cigarette factories in the country have used this product.

3.The spandex oil products become import substitution and China's first brand of spandex oil. In particular,

DY-103 spandex oil passed the provincial level appraisal of technology achievement. The certifying

committee agrees that: the product has reached the international advanced level of similar products. The

product accounts for more than 60% of domestic oil in spandex oil market.

4.MQ silicone resin products are various with unique properties, and new in silicone resins. These functional

materials are distinctive in the country and the application of them has been matured in antifoaming agent

industry, release agent industry, silicone rubber industry, and pressure-sensitive adhesives industry.

5.The latest synthetic leather pulp dewatering moisture resistant agent and printing paper-mold release

agent for synthetic leather are import substitution, break the monopoly of imported products in Chinese


6.The organic silicon pesticide wetting diffusing agent, which is a new type and special pesticide auxiliaries

of high efficiency, non-toxic and environmental protection, has been widely used in agriculture because of

its ultra-low surface tension, super permeability, wetting dispersibility and diffusing ability.

7.The series of organic silicon surfactant products are widely used in paint, printing ink and coating

systems, providing wetting and dispersion effect and the smooth feel, improving the brightness and scratch

resistance of the paint film.

8.The successful development of the series of polyurethane elastomer release agents makes the products

successfully out of the mould, the surface of which is smooth and bright. It is a kind of oily polyurethane

release agent, contributing to the molding of polyurethane elastomer products.

and low temperature resistance, aging resistance of all kinds of plastics as well as the flexibility of the


12.The methyl phenyl silicone resin used to make high temperature resistant insulating paint, high

temperature resistant coatings, and so on, the acrylic modified silicone resin used for buildings, vehicles

and other weather resistance coatings, the epoxy modified silicone resin used for high temperature

resistant anticorrosive paint and insulating paint of engine, wall pipe of exhaust pipe, chimney and other

parts, and other products have gone through novelty search by provincial searching organizations. No

relevant details have been found in the country.

13.Special organic silicon materials tailored for scientific research subjects of scientific research institutes

and institutions of higher learning are too numerous to mention, undertaking science and technology
