                                              One Component Polyurethane Foam Adhesive

Description
Flexibond 8083 is a one component moisture curable polyurethane foam adhesive. It is of fast curing speed, high bonding strength, good weather resistance, and it is easy to use.

Usages
Flexibond 8083 can bond various kinds of metal, wood, honeycomb paperboard, rockwool, perlite, calcium silicate board and etc. It is widely used for security doors, insulation and decoration integrated board, etc.

Application
1.Clean the surface of the substrates, which should be of no grease or rust corrosion.
2.In order to insure the bonding strength, the adhesive should be scraped uniformly on the surface of the substrates. The adhesive can be scraped with brush or plastic scraper. The adhesive film cannot be too thick, and the open time cannot be too long.
3.Pay attention to the adhesive coating speed. It requires fast operations in the summer time. Do not move to the press machine after the adhesive’ tack free. The adhesive can be processed with cold or hot pressing. If processed with cold processing, it takes at least 5-8h (relates with temperature); and if processed with hot processing, it takes 40-60mins (recommended temperature is 70-80℃). It takes more than 10 hours to achieve a high strength. The adhesive dosage varies with substrates.

Packaging
20kg/pail

Storage and Shelf life
The product should be stored in well ventilated, dry and cool place, avoid direct sunlight. The adequate temperature for storage is 15-25℃. The shelf life is 6 months if stored adequately.

Note
1.Operating the adhesive and press machine should be done within the tack free time.
2.The curing speed is affected by the surrounding temperature and humidity. The curing speed can be adjusted.
3.Seal the lid immediately if there is remained adhesive in the pail in order to avoid its curing.
4.Avoid eye contacting and ingestion. If contacting, wash with plenty of water and go to see a doctor.
