INTRODUCTION OF 8711
8711A/8711B is a two-component polyurethane adhesive for various
film/film laminates. 8711A/8711B is used for making high performance composite
films.showing excellent bonding performance. low viscosity and
short curing time; the film has a good wet ability and lower
solvent residues, suitable for high-solid, low–viscosity and
high-speed dry composite processing technology.
1. Dilution: Suitable solvents are ethyl acetate, acetone and Methylethylketone
provided that the water content does not exceed 300 ppm. Do not use
aromatic or alcoholic solvents.
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.
* Viscosity is based on the average viscosity of the Ford cup
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 4hours, if more than 4 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.
4. Application weight: Depending on the film or foil combination and the end use of the
laminate, the adhesive weight may range from 2.0-3.5g/m2 dry. For printed laminates the weight has to be adjusted
accordingly, it should be approx.0.5-1g higher than for unprinted
5. Dry: Composite equipment should have good air volume, wind speed, wind
pressure and the appropriate temperature, to avoid residual
solvents, peeling off bad. Temperature setting is generally
followed gradient principle(55°C-65°C,65°C-75°C,70°C-85°C)
According to the performance of the processed products, composite
raw materials, processing technology to adjust the temperature of
6. Storage: 8711 have a storage life of 9 months when stored at a cool and dry
place in unopened containers. Once opened, containers of
8711A/8711B should be closed tightly again and the material should
be consumed within a short period.
7. Transport: For details please refer to the corresponding safety data sheets.
8. Product certification: 8711 is in compositional compliance with FDA175.105
