Product Description
Product Description High performance PUR Hot Melt Adhesive for lens/case and housing assembly in cell phones and notebooks, MP3 players, portable batteries, and other consumer electronics

Instruction One component, moisture curing, urethane adhesive that is applied warm,and sets like a hot melt adhesive, but with a long open time for easy assembly of parts requiring a thin bond line.Specially designed for electronic components installation.It is solid at room temperature, heating when use,then coating, after the completion , will have good reaction with the the surrounding environment moisture to gain the best bonding effect Don't need additional heating during the reaction process, quick bond. This low viscosity adhesive has a long open time and is ideal for bonding plastics. Yields thin glue lines when used with appropriate equipment. Features Features • 100% solids • Long open time • Bonds a variety of plastics • One component • High tack • Reworkable after cured • Low viscosity • High strength bonds • High impact resistance • Excellent heat resistance • Excellent waterproof • Excellent temperature and weather humidity resistance • Can not be soak off even in the water for a long time • ROHS/without halogen/non-phosphoru/no benzene Typical Uncured Prop Typical Uncured Properties Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes.
Measured on Brookfield viscometer with Thermosel using spindle #27. The upper limit for bonding a 1/16" bead of molten adhesive on a plastic substrate in a room temperature environment. Open time is related to the solidification of the molten adhesive. The minimum amount of time required between when a 1" x 1" bond is made and when it will support a 5 psi tensile load on polycarbonate (PC) substrates. Open times and set times are based on a room temperature environment. High temperatures will lengthen open times and set times while lower environmental temperatures will shorten open times and set times. Operating Process 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 Industry 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. Typical Application Typical Application High performance for lens/case and housing assembly in cell phones and notebooks, MP3 players, portable batteries, and other consumer electronics • Thin, tough and flexible bond lines help improve fit, appearance,and reliability. • Excellent high strength bonds for plastics and metals, dissimilar substrates, and even hard-to-bond plastics such as polycarbonate. • No whitening, as often occurs with cyanoacrylate adhesives on plastic. • No plastic cracking, as may occur with ultrasonic welding Handling/Application Information Directions for Use Apply to clean, dried surfaces. Remove oil, grease and other contaminants by wiping with isopropyl alcohol. For materials that are often contaminated with mold release agents, it is recommended that the surface be solvent wiped, abraded and solvent wiped. For additional information on surface preparation, see section on Surface Preparation. • For best results, heat the syringe a minimum of 30 minutes at 110°C (230°F) before using. • Apply adequate amount of adhesive to one of the substrates to be bonded. Join the substrates within the adhesive’s specified open time and hold the bonded part until the adhesive has adequately set. Note: When using solvents, extinguish all ignition sources, and follow the manufacturer’s precautions and directions for use. Detailed Images
