What is hot melt adhesive for Door Casing?

Door casing moldings are usually used in combination with door frames. The door frame is the supporting structure of the door, which plays a role in fixing the door body. Door casing moldings are mainly used to cover the gaps between the door frame and the wall, providing sealing and protection.

Where is it used?

The "UNISN" hot - melt adhesive for bent moldings is mainly applied to the spray - bonding of solid wood boards, multi - layer solid wood boards, and clips during the production of door casing moldings by wooden furniture manufacturers.

Who uses it?

•Furniture manufacturer  •Wood door manufacturers  •Wood board manufacturer  •And more

How to use?

Most production lines are equipped with one large and one small glue - melting tank. The large glue - melting tank supplies glue to the spray - bonding lines on both sides for bending, while the small glue - melting tank is used for bonding the bottom of the core board and the clips. A few production lines are equipped with two small glue - melting tanks or only one large glue - melting tank

Usage and Precautions

•Open Time: 10 - 20 seconds
•Operating Temperature Settings: Glue - melting tank: 180 - 200°C; Hose and spray gun: 180 - 190°C.
•Note: In cold environments, the hot - melt adhesive dissipates heat quickly, and the operating temperature of the hot - melt adhesive needs to be increased by at least 5°C.

In addition, note the following:

1.Pre - heat the glue - melting device for about 2 hours first.

2.Control the amount of glue added according to the production volume to prevent over - heating due to incomplete consumption over a long period, which may cause the glue to age and affect its adhesion. Also, avoid insufficient consumables, which may affect glue spraying.

3.After replenishing consumables, reseal the packaging bag and cover the glue - melting tank to prevent impurities from mixing in and blocking the hose and spray gun.

4.The bonding work must be completed within the open time of the glue. Clamp the adherends until they are completely cooled and cured.

5.Since the glue - melting tank and the glue - spraying system are at high temperatures, safety protective equipment must be worn during operation to prevent burns.

6.Avoid contact between the melted glue and parts such as eyes and skin.

7.If the melted glue comes into contact with the skin, immediately immerse the affected skin in cold water and rinse for at least 10 minutes. Seek medical treatment in a timely manner after cooling.

Usage and Precautions

•Fast Melting Speed: It can transform from a solid state to a liquid state in a relatively short time, enabling quick use and improving production efficiency.
•Good Fluidity: It can be quickly and evenly coated on the surface of the adherend and fit well, ensuring the integrity of the bond.
•Fast Curing Speed: It allows the adherends to be fixed rapidly, greatly shortening the production cycle.
•High Bonding Strength: It has good bonding performance with various types of wood, ensuring that the bonded objects will not easily fall off or separate.
•Good High - Temperature Resistance: It can still maintain good bonding strength and stability in a certain high - temperature environment, making it suitable for high - temperature applications.
•Environmentally Friendly and Harmless: It is made from environmentally friendly raw materials, causing no pollution to human health and the environment. It can be widely used in fields with high environmental requirements.
