Technical Data Sheet of 825Spandex adhesives
825 is elastic-attachment hot melt adhesive designed for diapers, also can be used as construction adhesive. With light color, low odor, good liquidity when coated, great creep-resistance and aging-resistance, 825 can bond non-woven/PE films/elastic ribbons strongly and can be widely suitable for many applicators.

Its adhesion performance will be affected by substrates, release paper and application environment, so trial run is necessary to determine whether the adhesive is suitable.
There should be no dust or oil on the surface of substrates and release paper, also the substrates and release paper should be treated to constant temperature and humidity before application.
Recommended application temperature：140-170℃
Application methods: slot, spiral spray, fiber spray, multiline ，etc.

Packaging: 20Kg/carton, about 0.83Kg/cake, wrapped with fusible films
The residual adhesive can be rubbed off by wooden shovel before it is totally cooled. Cooled glue can be cleaned with specialized detergent. Applicators can be cleaned with mineral oil at 120℃, then purged with hot melt adhesive.
Don’t mix the product with other adhesives.
Keep the adhesive containers covered to avoid dust or contamination.
Use it with adequate ventilation to remove any hot melt fumes or vapors that are generated
Wear safety glasses, safety gloves and safety clothes when using hot melt adhesive to avoid scald.
