JSW bbbbl hot melt adhesive film，It is essential, as with all pressure-sensitive tapes, that the surface to which the tape is applied be clean, dry and free of grease and oil.

Shelf life from date of manufacture is based on the product being stored at 70°f(21°c) / 50% relative humidity out of direct sunlight.

With the rapid development of JSW- JSW615 hot-melt adhesive technology, in recent years, bbbbbb TP lens bonding technology has made a lot of significant progress in China. For example, for the application of PMMA, acrylic, plexiglass, narrow frame plastic parts, digital product display screen, touch screen, TP lens professional assembly project, JSW has carried out many tests since 2012, but no quality problems have been found, some special cases are also the first in the world.

Curing perbbbbance ofJSW plastic hot melt adhesive film:

Working temperature (- 40-95 ℃) shear strength (15-22 MPa)

Softening point (90 ℃ ~ 110 ℃) elongation (50 ~ 85%)

Shore hardness (ASTM b2240) (40d) tensile strength (20-28mpa)

The bbbbbb uses JSW plastic hot melt adhesive film as the adhesive, which should have the maximum wetted area and measure the roughness of the solid. When the surface roughness increases, the wetting process can be spontaneous. The wetting kinetics and speed of JSW plastic hot melt adhesive film are related to the surface structure, viscosity and surface tension of the adhesive. Because the surface tension of organic solid is not very different, the soaking time ofJSW plastic hot melt adhesive film mainly depends on the viscosity and contact angle of hot melt liquid. It can be seen from the above that the lower the viscosity of hot-melt liquid is, the shorter the soaking time of JSW plastic hot melt adhesive film is, the more the gap on the surface will be fully soaked; the smaller the soaking time is, the faster the soaking speed is. The best condition of bonding surface chemistry when the adhesion work of JSW615 hot melt adhesive to the surface is the largest or the interface energy is the lowest, the bonding strength is the best. This is the best condition of bonding surface chemistry.
