Hot Melt Adhesive

Product Details:

KH-112B  Polyurethane Hot Melt Glue

Instruction for Use
For best results, ensure parts are clean, dry and free fromoil and grease, although good bonds can still be achieved on ‘as received’ or slightly oily parts. The temperature of substrate should not be lower than 20???. Low temperature will shorten the open time and cause the bonding failure. If needed, pre-heating of the substrate is recommended. Dispense bead of product onto substrate. Mate opposite substrate within recommended open time. Allow for handling strength to be achieve.

Description
Krylex KH112B is a one component reactive polyurethanehot melt. It is solid at room temperature. After being applied warm the product will cool to allow immediate handling. Upon further exposure to ambient humidity Krylex KH112B will achieve high strength bonds and excellent environmental resistance. 

KH-112B hot melt glue is a one-component reactive polyurethane hot melt adhesive. This reactive hot melt adhesive is solid at room temperature. After heating, it will cool for immediate handling. Upon further exposure to ambient humidity, KH-112B hot melt glue will achieve a high strength bond and excellent environmental resistance.

Instructions
For optimal results, make sure that the parts are dry, clean, and free of grease and oil. However, good bonding can still be achieved on parts that are "as received" or slightly oily. The substrate''s temperature shouldn''t be any lower than 20°C. Low temperature will shorten the open time and cause the bonding failure. Pre-heating the substrate is advised if necessary. Dispense bead of product onto substrate. Within the suggested open time, mate with the opposing substrate. Allow for handling strength to be achieved.

Storage
Optimal storage conditions are between 15°C to 30°C and stored in original sealed foil bag. Storage outside this temperature range can adversely affect product properties and may reduce the stated shelf life.
