Features:
The binder for the metallized structure is a single component design and production , water-soluble acrylic composite adhesive, do not add organic solvent-based adhesives are environmentally friendly, can get a good working environment. Coating can be directly used in the case of a lower coating weight of the composite strength can get better. The beginning of the adhesive has a high strength composite, is not strict requirements on the aluminum substrate, aluminum layer to improve the transfer, it is ideal for composite aluminum structure products.
Adaptability of the adhesive ink, with common chlorinated polypropylene, polyester, and other types of alcohol soluble ink for complex, especially compound difficult spots and white ink.
Wide range of product adaptability: can be used in BOPP, PET and CPP, PE, metallized, paper, composite substrate suitable for light dry packaging.

Codex Alimentarius:
QQ-3042 Water-based acrylate adhesives Line with China's Adhesive Industry Association adhesives for food packaging regulations, and the Chinese Food Hygiene.
Use:
1, using water-based adhesives to water-based adhesives before slowly mixing in barrel 5 to 10 minutes, to ensure water-based adhesives in a variety of additives mixed.
2, as far as possible the uniform use of the reverse rotation roller, reverse roller absorb a great impact on the apparent, by adjusting the speed, can make apparent the best results.
3, the resin content and composite material structure according to different requirements in 1.5-3.0g/m2 adhesive strength within the adjustment.
4, drying temperature, air velocity, the speed settings are to ensure complete drying layer of a substrate, taking into account the principle of tolerance, refer to the three-zone temperature is 80 ℃, 85 ℃, 95 ℃;
5, composite roll temperature and pressure under the membrane performance as high as possible, the proposed composite temperature between 60 ℃ -80 ℃ prior choice to not undermine the principle of materials (high temperature and pressure get a better look and composite peel strength);
6, at 45-50 ℃ curing composite membrane can be used after 4 hours;
7, after the end of production, water cleaning equipment, consolidation of material by solvent cleaning.
