AD4001 METAL TO METAL is a two component, room temperature curing, black coloured, odourless, thixotropic polyurethane adhesive. Polymix metal bonding system is an innovative system to glue metal panels. Specifically designed for the automotive aftermarket can easily replace the traditional spot welding technology. 20 minute working time.
BONDING VS WELDING
- No need to remove internal panels and rubber gaskets.
- No need to re-shape the metal deformed by the welding heat.
- No need to grind the welding spots.
- No need to disconnect the electronic system of the car as with tradition welding.
- No need of rust protection primer on the bonded area.
- No need of sealers because Polymix metal bond is a self sealing adhesive.
AREA OF APPLICATION:
Small metal panel adhesive. Exceptionally strong urethane adhesive for bonding small steel parts, such as bumpers and quarter panels where a 20 minutes working time is needed. Bond or declamp time is 4 hours (use heat @ 60 C to reduce declamping time to 1 and 1/2 hour).
PRODUCT APPLICATION:
AD4001 is available in bi-component cartridges by 50 ml and 178 ml. Blending should be made through static mixer composed by a minimum of 20 elements.
REACTION MECHANISM:
The speed of the harden reaction is mainly influenced by two factors: the application temperature and the application thickness. Being the reaction exothermic, the speed decreases as the thickness and temperature application decreases. The maximal temperature of the reaction will be reached in 5 mm. application thickness and is always lower than 40 C.

PRODUCT STORAGE:
AD4001 has a shelf life of 12 months from the initial production as long as it is stored in a cool and dry place, between +10 C and 25 C. Expiry date is indicated on the label. The cartridges have to be kept in a sealed plastic bag and protected from light and heating sources inside the original packaging. Once opened, the cartridges will last until the expiry date (as long as the above conditions are met) leaving the last mixer used onto the cartridge.
PRODUCT HANDLING CAUTION:
Adhesive Dispensing Ltd products are generally quite harmless to handle provided that certain precautions are normally taken when handling chemicals are observed. The uncured materials must not be allowed to come into contact with foodstuffs or food utensils, and measures should be taken to prevent the uncured materials from coming in contact with the skin, since people with particularly sensitive skin may be affected. The wearing of impervious rubber or plastic gloves will normally be necessary; likewise the use of eye protection. The skin should be thoroughly cleaned at the end of each working period by washing with soap and warm water. The use of SOLVENTS has to be avoided. Disposable paper should be used to dry the skin. Adequate ventilation of the working area is recommended. These precautions are described in greater detail in the Safety Data Sheet for the individual products and should be referred to for further information.
