Curing agent development Suggestions

Curing agent development Suggestions 1. Determine the curing agent of epoxy resin industry is the development direction of premise at the beginning of foundation. Fine and specialty chemicals, development of curing agent belongs to the typical curing agent is of great significance, but it is not easy, we must press than fixing agent the characteristics and laws of development.

Curing agent development Suggestions 2. Overall planning, and guide the orderly development (including project, funds, research, application, production and sell goods on a commission basis, etc.). Chemical and China petrochemical corporation should incorporate firming agent in epoxy resin and the "ninth five-year plan" period in 2010 the form a complete set of vision, in the construction of epoxy resin production plant in the future at the same time, should be synchronous construction curing agent production equipment.

In the introduction of epoxy resin manufacturing technology at the same time, should be synchronized to introduce production technology and formula of curing agent application technology. Development of curing agents and epoxy resin and curing agent factory existing technological upgrading and product upgrading, the combination of enterprises choose the above conditions better, the preparation of 2-3 comprehensive (research, production, application, service, management) curing agent professional production base (including northeast 1, south China, east China's 1), in order to form the climate and the overall advantages, and domestic curing agent of famous brand. Improve the level of technology of epoxy resin industry in China play by large enterprises, to accelerate the development pace also want to rely on large epoxy resin curing agent business.

Curing agent development Suggestions 3. Curing agent must pay attention to the scientific research development, in accordance with the scientific research, leading to research. Research work is the essence of innovation, innovation is the soul of the curing agent business. Must be based on technology development, the use of existing chemical structures of curing agent, using methods such as chemical, physical modification, to improve its performance, new varieties, new brands.

Curing agent development Suggestions 4 Suggestions must be under the big effort to improve the quality of curing agent application development, market development and technical services. From product research and development to establish application technology and commercialization of technology research team, to engage in curing agent formula, use and processing technology research and performance evaluation.

Also attaches great importance to the market forecast and perfect technical service system, to maximize meet the needs of different users for a variety of practical function. Curing agent development include: the development of new chemical structure, application development and market development, each have emphasize particularly on three aspects, are inseparable.

In fact, foreign agent varieties, specifications, seriation, specialty is on application development and for the first-hand information from the user's technical service work.




Chinese name: Diethyl toluene diamine(DETDA)

Diethyltoluenediamine Uses:

The product is identical to Ethancure 100 and Lonza DETDA 80, DETDA is very effective polyurethane elastomer chain extender; also be used as polyurethane and epoxy resin curing agent, epoxy resin of an antioxidant, industrial oils and lubricants . In addition, also as intermediates in organic synthesis.Especially for the RIM (reaction injection molding), is important in the field of spray polyurea chain extender species. Also can be used for casting polyurethane elastomer (CPU) and a curing agent, epoxy curing agent, epoxy resin of antioxidants, lubricants and industrial oils other antioxidants.


Curing agent development Suggestions 5. Establish comprehensive multi-purpose production workshop, the curing agent product development group (product or product line) tree. In order to adapt to curing agent varieties and specifications, small batch and the particularity of the market demand is protean, the enterprise shall establish flexible and economic efficient of multifunctional production curing agent "workshop" kitchen, unit operation equipment, both for pilot, but also for use in production.

Curing agent development Suggestions 6. Actively develop new varieties, improve the grade of products, trying to catch up with curing agent for advanced level in the world. According to the domestic market demand and combining with the curing agent varieties of structure and development trend at home and abroad, a suggestion of strength development of the following varieties: (1) the new amine curing agent. Amine curing agent in the prominence of curing agent and dosage the biggest, most varieties, about 80% of the total curing agent.

In the future should focus on and develop the modified amine and polyamide curing agent series. (2) new acid research department than fixing agent. Under the normal temperature of liquid acid is the main attack direction in the future, should develop the domestic market gap is very big and wide prospect of the liquid isomerization methyl phenol and methyl phenol six hydrogen, four hydrogen and other high performance liquid anhydride, moderate development such as methyl dick anhydride (MNA). (2) water-based special water-soluble epoxy resin curing agent. (1) curing speed, good color, easy to spread, easy to operate, save energy special curing agent of epoxy powder coating.

Curing agent development Suggestions 7. Will take the project as the core into a technology as the core. Development of curing agent can't like to get bulk chemical products project as the core, with technology as the core, focusing on the complete product solutions and series of product development

Epoxy resin must react with curing agent to produce three to the three-dimensional structure is the practical value, that therefore the structure of the curing agent and the quality will directly affect the application effect of epoxy resin.

At present our country has become a great nation of production and consumption of epoxy resin, and for the research and development than epoxy resin curing agent, compared with the varieties of epoxy resin curing agent varieties more, and confidentiality is very strong, and the present situation of the domestic backward development of curing agent, experts are calling for the development of epoxy resin curing agent on the important agenda as soon as possible, forming a complete industrial chain.
