                              New solution for TP and bracket PUR hot melt adhesive dispensing

PUR hot melt adhesive dispensing processing is currently a new solution for TP and bracket bonding, with high efficiency, easy repair, and no adverse effects! The adhesive used for bonding the touch screen of the mobile phone to the frame (probably the best frame bonding solution at present). At present, smart phones are developing in the direction of large screen and narrow frame. The glue has failed to meet the requirements of various indicators, so more and more manufacturers adopt the glue dispensing scheme of PUR hot melt glue dispensing.

Glue used for TP and bracket:
Because the tempered glass screen is sprayed, and the area is narrow, and the brackets are also deformed to varying degrees, only non-corrosive, high bonding strength, easy disassembly and rework, and good weather resistance adhesives can be used.

Overview: The glue used in PUR hot melt adhesive dispensing is a cross-linked structural adhesive with high bonding strength, which has good fluidity when heated and is convenient for coating. It has the characteristics of rapid heating and melting, and rapid cooling (about 60s) to achieve high-strength adhesive force. It can meet the bonding requirements of structural components of mobile electronic products.

Applicable substrates: ABS polycarbonate (PC), PS glass products, UV-coated polyester (including DCPD modification), aluminum alloy (better anodized treatment), nickel-chrome plating (rough surface), bonding the same material or different materials.

Main technical indicators of PUR hot melt adhesive: appearance: gray cured body; opening time (23°C): 120 (seconds); specific gravity (g/cm3. 25°C): 1.12; viscosity (185°C) (cps): 5000- 7000; cured content: 100%; sizing temperature (°C): 110°C ~ 120°C; temperature resistance after curing (°C): -40°C ~ 90°C, the opening time shown here refers to the condition of 23°C Next, the time for the adhesive to cure.

PUR hot melt adhesive product description: PUR hot melt adhesive used in PUR hot melt adhesive dispensing processing is a single-component polymeric compound with a high solid content. The product is solid at room temperature. Heating sizing, after the gluing is completed, the product can react with the humidity of the surrounding environment to produce a strong adhesive force, and no additional heating is required during the reaction.

PUR hot melt adhesive product characteristics: 100% solid content. low viscosity. High initial adhesion. Suitable for bonding of plastics, glass, ceramics and metals. Lower gluing temperature (90°C-110°C). Good heat and solvent resistance. Good water resistance. Good high and low temperature resistance.

Application of hot melt adhesive dispensing processing products:

It is suitable for bonding various plastics, and is suitable for bonding lenses, small joints for box assembly and other fields. It is suitable for bonding in the electronic field, various communication modules and products, mobile phone casings, GPS, car DVD casings, shielding covers, MP3 casings, and other plastic products, so that the products can meet the expected requirements.
