PU FOAM For Aluminum alloy and plastic plate
Product Description
PU Foam for making fire door and sanwishboard has the characteristics of high bonding strength, good weather resistance, ease to use, and water resistance, and is widely used in wood, metal, foam, etc.
PU foam has the Strong adhesion, shear, peel strength, high temperature resistance, hydrolysis resistance, heat resistance, aging, etc.
Physical properties of PU foam after curing at room temperature can be achieved at room temperature.
The running time of the PU Foam is highly adjustable, and PU foam can be selected according to different curing times.

4, How to use about PU Foam:
(1) Brushing process: The surface of the coating is coated with the surface of the working surface, and then the coating is adhered to the surface. The anti-theft door is to use a clean surface to paste the surface cleaner, no rust, no grease, and a clean surface will affect the bonding effect.
(2) In order to ensure the bonding strength, please apply the glue evenly on the surface of the adherend, and brush it with a plastic scraper. Due to the high-viscosity glue, you cannot roll the glue by hand. The amount of glue can be adjusted according to the depth of the door. Sure. Please apply the glue evenly on the surface, if it is too thick, the exposure time
not too long.
(3) Pay attention to the speed gluing process, and the coating is uniform. The summer is fast, it is not the number of times to go back and forth, if the movement is slow, you can even apply pressure on the edge glue machine, and apply pressure when the non-stick surface is dry. Welding can be cured by cold or hot pressure, the cold curing time is not less than 3 ~ 4h, and the heat curing time is 15 ~ 30min; after more than 24h, it can be baked: the baking temperature is 190 ~ 220C.
(4) It is good not to use glue to cover the cover. The tool can be cleaned by dissolving in ethyl acetate or soaking in warm water for a few minutes before washing with soap.
This PU Adhesive product should be stored in a dry, ventilated and sealed environment without contact with water.
