ECO series alcohol-soluble polyurethane adhesive is a technology imported from the United States by Occidental Industries (Shenzhen) Co., Ltd., a wholly-owned subsidiary of OM EX GROUP, Inc. Time to develop environmentally friendly adhesives. This adhesive is mainly applied to the bonding and compounding of plastics, aluminum foil, paper and other materials. It is also widely used in pre-treated PET, OPP, BOPP, CPP, PE, CPE, LDPE, PA, PT, aluminum foil, vacuum plating. Dry compounding between film substrates such as aluminum film and paper.
ECO 501 alcohol-soluble polyurethane adhesive is a two-component adhesive, the main agent and curing agent do not contain isocyanate groups (-NCO) and highly toxic free isocyanate molecules (TDI), made with industrial ethanol Solvent can meet the requirements of use, and thus is an environmentally friendly product. Like solvent-free adhesives, it represents the direction of the development of laminating adhesives industry. In the future, it is expected to become the new generation of plastic flexible packaging adhesives in China.
1. Advantages of alcohol-soluble polyurethane adhesives ECO 501 alcohol-soluble polyurethane adhesives have the following main advantages compared to ethyl acetate solvent-based polyurethane adhesives that are currently in widespread use in China:
1. Both the main agent and the curing agent do not contain isocyanate groups (-NCO) and highly toxic free isocyanate molecules (TDI). They are safe and non-toxic during the operation and use of composite products. They are environmentally friendly. Agent.
2. The film has good initial tackiness, and the composite film has high transparency and excellent smoothness.
3. It is not sensitive to wet climates, it is not affected by the external environment during the lamination process, it is easy to use and it is not prone to quality accidents.
4. It is suitable for the compounding of a variety of films and is widely applied to various types of inks, especially for environmentally friendly alcohol-soluble inks, without ink smudging.
5. The curing time of composite products is short, which can reduce energy consumption, improve work efficiency, and can also mature naturally.
6, the use of industrial alcohol or other alcohol solvent dilution, good health performance, low overall cost. It is non-toxic to the operators, has no pollution to the atmosphere, has low solvent for residual film, and has significant social benefits.
Second, ECO501 alcohol-soluble polyurethane adhesive bonding principle Alcohol-soluble polyurethane adhesive technology is relatively high, at present there is no other domestic manufacturers of this product, only a few foreign companies have mastered the technology.
ECO501 alcohol-soluble polyurethane adhesive is a non-toxic polymer adhesive material, which can be widely used in the bonding and compounding of plastic, aluminum foil, paper and other materials, and has excellent performance. It is distinct from the curing mechanism of solvent-based polyurethane adhesives and solvent-free polyurethane adhesives, which are commonly used as a solvent for ethyl acetate. The technology is critical in the A component (ie, the main agent) and the B component (ie, the curing process). The agent) does not contain an isocyanate group (-NCO) in its molecular chain. The NCO group is toxic and can easily react with the hydroxyl group (—OH). Therefore, in the process of using a polyurethane binder containing an —NCO group, it is absolutely impossible to introduce substances such as water and alcohols containing hydroxyl groups. Doing so will cause the adhesive to denature and become unusable. ECO 501 alcohol-soluble polyurethane adhesive is not only not afraid of hydroxyl substances, but the introduction of hydroxyl groups during the curing process can also improve its adhesive properties.
Third, the development prospect of ECO 501 alcohol-soluble polyurethane adhesive The solvent-based adhesive used in plastic flexible packaging, to reduce the toxicity of the adhesive itself and the development of the use of environmentally friendly solvents is an inevitable trend.
Currently, two-component polyurethane adhesives using ethyl acetate as the solvent are commonly used in China, although its adhesive properties can meet the requirements. However, due to the high NCO groups and highly toxic free TDI in the curing agent, the worker's health is greatly damaged during the sizing operation. During the storage and use of composite products, TDI hydrolysis may also occur, releasing toluenediamine (TDA) into the food, and TDA is a carcinogen, which has potential harm to human health. In addition, the solvent ethyl acetate used by it also has certain toxicity and strong irritation, which is very harmful to the workers and causes pollution to the environment. Therefore, in some developed countries in Europe and America, such two-component polyurethane adhesives using ethyl acetate as a solvent have been successively restricted or prohibited.
ECO 501 alcohol-soluble polyurethane adhesive, which itself does not contain -NCO groups and highly toxic free TDI components, and solvent industrial ethanol used in the compound is also non-toxic, so it is environmentally friendly to meet the needs of social development. adhesive.
At present, adhesives used in the packaging industry in developed countries in Europe and the United States have generally adopted environmentally friendly products. Alcohol-soluble polyurethane adhesives are among them. Although some developed countries in Europe and the United States have begun to use a large amount of two-component solvent-free adhesives, due to factors such as cost, adaptability and other factors, there are still about 40% solvent-based adhesives, of which more than 95% are used. Alcohol-soluble adhesives.
Due to the large viscosity of solvent-free adhesives, most of the dry laminators currently used by laminating packaging companies in China cannot uniformly coat them, and must use solvent-free special composite equipment. The equipment needs a large amount of funds to be updated and Take longer to complete.
At present, China is still unable to produce solventless dry laminating machines. Currently, more than 20 non-solvent compounding production lines in China are all imported equipment. All solvent-free adhesives used are also supplied by imports. Equipment investment is high, and production costs are high. Solvent-free special compound equipment gluing system has a complex structure, is difficult to operate, and requires high technical requirements. It requires special training for operators and requires workers to have extremely high operating standards to ensure product quality; due to the flexible packaging companies in China Due to the small size, large quantity, and fierce competition, there is a problem of insufficient business volume. This can not meet the need for high-speed operation of solvent-free composite production lines. As a result, some manufacturers' equipment is often idle and equipment utilization rate is very low. These factors greatly restrict the promotion of solvent-free composite technology in China. Therefore, due to different national conditions, the road to popularizing solvent-free composite equipment and solvent-free adhesives in China is still quite long.
The use of ECO 501 alcohol-soluble polyurethane adhesive eliminates the need to update existing dry composite equipment, so it is possible to increase product quality and meet environmental requirements without additional equipment upgrades and other expenses. At the same time, the main operation method is the same as the existing ethyl acetate solvent-based polyurethane adhesive, and no special training for operators is required.
Prior to this, alcohol-soluble polyurethane adhesives had no official products in the country and the demand was completely dependent on imports. The price of imported 70% solids alcohol-soluble polyurethane adhesive is 4.5-50,000 yuan/ton, which is more than double the cost of the commonly used ethyl acetate solvent polyurethane adhesive. In China, only a few foreign and joint venture laminating packaging companies are used, and most overwrapping and packaging companies find it difficult to accept them. Therefore, imported alcohol-soluble polyurethane adhesives are difficult to popularize.
Europe and the United States Branch Industrial (Shenzhen) Co., Ltd. to the ECO 501 alcohol-soluble polyurethane adhesive to a wide range of users at a reasonable price and quality service. I believe that in cooperation with the efforts of all the friends, ECO 501 alcohol-soluble polyurethane adhesive will bring new opportunities for the development of the majority of users, and jointly promote the development of China's packaging industry.
