Properties

1. 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

* Viscosity is based on the average viscosity of the Zahn cup 3#/25°C

2. 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 good adhesive should be used up within 2 hours.

3. Application weight: Depending on the film or foil combination and the end use of the laminate, the adhesive weight may above 1.8g/m2 dry. For printed laminates the weight has to be adjusted accordingly.

4. Packaging specifications
8720A:20KG/bucket
8720B:3KG/bucket

5. 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.
