At present, the situation in which domestic polyester adhesives dominate the world will change. The recent introduction of polyether adhesives by Jintan Adhesives will bring good news to printing companies that want to reduce the amount of solvent residues and make it difficult to reduce costs.
The problem of residual solvents has now become the focus of attention in the industry. Manufacturers are looking for ways to reduce residues. Adhesives play a key role in this issue. Polyether adhesive is a kind of water-based polyurethane, its advantages are low residue, good leveling, high transparency, excellent performance, especially low residue makes it have a great deal with polyester adhesive. Capital. Foreign large-scale adhesive companies, such as Japan's Mitsui Takeda Adhesives, which have entered the Chinese market, are all types of polyether adhesives, but relatively high prices make most companies unable to consider them.
However, for a long time, why did the domestic polyether adhesives not dominate? Senior expert Jiang Zhongqiu said: Polyester adhesives are relatively low-cost, but also related to the company's habits. Polyester type and polyether type adhesives are not allowed to be mixed. In the production, different plastic tanks and rollers need to be replaced. Even scrapers must be thoroughly cleaned. In addition, considering the price factor, companies generally do not actively choose Polyether adhesives.
Japan, Korea, and other countries have always dominated polyether adhesives, and are related to national industry regulations. For example, high requirements for residual solvents, appearance, and composite strength make companies want to start from various raw and auxiliary materials. Make every effort to ensure the last high quality.
Jiang Zhongqiu engineers also said that the domestic adhesive manufacturers are gradually changing the tradition of using adhesives for all composite flexible packaging. The adhesive factory began to tailor-make adhesives for enterprises according to the needs of manufacturers, such as gold. The adhesive company of the altar has introduced special aluminum-plated composite adhesives, aluminum-plastic composite adhesives, fast-curing adhesives, cooking adhesives, and anti-slip agents. Jiang Zhongqiu believes that the subdivision of adhesives has become a trend, and many domestic adhesive manufacturers are conducting corresponding research according to the specific requirements of customers.
