Product Description

Introduction of 8728

8728A in combination with Hardener 8728B is a two-component polyurethane adhesive for various film/film and film/metalized filml laminates. This product has good flexibility and good transparency, can effectively reduce the characteristics of aluminum transfer and prevent the phenomenon of tunnel.


— High solid content, low viscosity;

— Specially design for VMPET VMCPP;

— Vacuum packaging film.

Applicable structure







1. Preparation of Adhesive Mixture: After having added the right quantity of solvent to 8728A and having achieved the required solids 8728B has to be stirred into the 8728A/solvent mixture.

2. List of dilution: When the ethyl acetate is used for dilution, to obtain an accurate solid content, it is required to refer to the following solvents.

8728 A 8728B Solvent Solids Content Viscosity
20KG 4KG 18.6KG 40% 16-19s
20KG 4KG 24.6KG 35% 13-17s
20KG 4KG 32.5KG 30% 10-15s
20KG 4KG 43.6KG 25% 8-12s

* Viscosity is based on the average viscosity of the Ford cup 4mm/20°C

3. Pot life: The ready-for-use adhesive in closed containers has a working time of about 8 hours. The composite machine is not used up of adhesive, the retention time of more than 2 hours, if more than 2 hours should be abandoned, otherwise it may lead to unstable composite films.

Tropical area (Temperature >28°C + humidity >60%) pot life: Mixed adhesive should be used up within 2 hours.

4. Coating : 8728 adhesive is suitable for dry composite device with smooth light roller or concave roller. Before mass production, repeated trials should be carried out to determine the fit of the wire roller.

5. Matters needing attention: As the adhesive contains polyisocyanates any contact with skin has to be removed.

6. Others: Film additives-particularly slip agent content in LDPE,MDPE and CPP films-packed goods, printing inks, pre-treatment and coating of films are of significant importance to the end use of the laminates and may affect the performance properties either straight away or later. Therefore, practical laminating tests as well as checks on the laminates are necessary before going into full scale production.
