In order to adapt to the current macroeconomic situation, the domestic production of adhesives main strategies adopted by enterprises as follows.
(1) Low TDI monomer residue adhesive. Still widely used for the current type of aromatic ester solvent free polyurethane adhesive TDI problems exist, as far as possible TDI monomer residual curing agent, curing agent in the original TDI residue ≤ 1% or promote the use of TDI is not used as a the curing agent of raw materials, thereby significantly reduce the likelihood of toluenediamine.
(2) an aliphatic adhesive. Vigorously promote the use of aliphatic polyurethane adhesive, completely eliminate the root causes of toluene diamine.
(3) reduce VOC emissions. Promote the use of high concentrations of coating technology, while maintaining the same amount of glue under the premise, significantly reducing the amount and diluent volume application voc ~ ~ solvent recovery technology to further reduce VOC emissions, and to achieve effective VOC recycling .
(4) zero emission direction - no solvent-based adhesives. Promote the use of solvent-free adhesive to completely eliminate VOC emissions. This goal will take a composite flexible packaging equipment companies supporting renovation work and investment is large, truly large-scale promotion still time.
(5) water-direction. Promote the use of water-soluble polyurethane adhesive and acrylic adhesive, with a view to the total elimination of VOC emissions and toluene diamine risks. Water-soluble acrylic adhesive into the Chinese market a little longer in the water-soluble polyurethane adhesive, but because of the acrylic adhesive (including water-soluble and alcohol-soluble) in overall performance inferior to polyurethane adhesives (including ester-soluble and water-soluble). Only minor advantage in terms of cost, which is likely to be a transitional product and gradually fade out the market.
It is foreseeable that in the future for a long period of time will continue to market our adhesive solvent-based polyurethane adhesive led, solvent-free polyurethane adhesive and water-soluble adhesive growth will accelerate, and the water-soluble polyurethane adhesive a water-soluble adhesive agent is the direction of development. In short, the future of China's market will be solvent-based adhesives adhesives, solvent-free
