Product Description

Item No.: WTS-7118


WTS-7118 is a reactive hot-melt adhesive based on polyurethane prepolymers. The adhesive is pressure sensitive and provides a high initial strength instantly after joining the parts. Additionally it has a long open time to be suitable for automatic or manual assembly line.


The bonding range of a 1mm bead of molten adhesive on substrate. Open time is based on a room temperature environment. Higher temperature will lengthen the open times while lower environmental temperatures will shorten the open times.

PUR Hot melt Adhesive Operating Process

Remove the scabby glue ,install the needle, with the

operation time ≤2mins

1. Preheating

2. Drop the Glue

3. Assembly and Press

4. Let it be for 30mins

5. Disconnect the fixture for the next assembly



Disassembly process

While heating, applying external force is the effective method of heavy



1. For bonding the LCD module and the border, heated for 5 to 15 minutes @65-80 , while applying for 5-10 kg force (thrust and pressure), so it is easy to separate parts


2. Clean with mild solvent to wipe off the residue glue on the LCD module (such as isopropyl alcohol, n-heptane, etc.), avoid solvent into the LCD module to cause damage


3. Suitable heavy industry system will greatly improve efficiency


4. It is better to test LCD module whether also can work normally after the heating, to modify the heating temperature and external force size according to it.
