JSW3542PUR called the moisture-curing hot melt adhesives reactive polyurethane hot melt adhesive, its mechanism of action is a polyurethane prepolymer reaction with moisture in the air, PUR hot melt adhesive curing and cross-linking to form a stable chemical structure. Sizing convenient, low melting point, 110 ℃ to sizing. Widely used in mobile phones, tablet computers narrow border adhesive solutions, PUR hot melt adhesives have good weather resistance: Because after the bridge have irreversible characteristics, and thus will not be affected by changes in ambient temperature creep and brittle hair. High toughness, tack and strong, with a strong permeability and affinity, the adhesive strength of 40% to 60% higher than other adhesives under the same conditions, reducing the amount of adhesive. PUR hot melt adhesive evenly good impact resistance. Various substrates with good adhesion properties. PUR hot melt adhesive product characteristics: (1) good adhesion: a variety of substrates can be bonded (such as PP, PC, ABS, PMMA, metal, glass, etc. TP lens bonding) above is a simple hot melt PUR presentation, need details please go gold Shengwei Guan network download. The following is the PUR hot melt adhesive informal information purposes only. Not only can be used for various electronic products adhesive TP screen is fixed, PUR hot melt adhesives can also be used to seal some of the windows and other components need to be fixed, the connection of the occasion. After PUR hot melt adhesive products chemical resistance and solvent resistance, alkali class, but allow it to warm to soften. Curing insoluble in water, glycerin and the like, but can swell to absorb alcohol, and stress cracking. PUR hot melt adhesives and other inclement weather with good resistance to weathering capabilities. Has excellent resistance to atmospheric aging, its sample test after four years of natural aging, weight changes, tensile strength, light transmission rate decreased slightly, slightly yellowed color, anti-crazing not decreased significantly, the impact strength also increased slightly, PUR hot melt adhesive is almost no change in other physical properties. Some people say that the establishment of a strong brand PUR hot melt adhesive force requires a long process, but JSW in just a few years to create its own strong brand position PUR hot melt adhesive, its brand equity in the industry far beyond a few decades-old brand. JSW brand grow to large enterprises proved PUR hot melt adhesive brand in a short time can shape up. PUR hot melt adhesive so that the brand-building issue is not the duration of the problem, first awareness of the problem, then the PUR hot melt adhesive marketing strategy. PUR hot melt adhesive is only involved in the weak force, electromagnetic force and gravity, without participating in the general term for strongly interacting particles. PUR hot melt adhesives total of six, including electronic, electron neutrino, μ son, μ neutrino, τ son, τ neutrino. Electronic, μ and τ child is charged child, all the PUR hot melt adhesive is not charged, and all of the neutrinos exist antiparticles; τ is an important sub-particles discovered in 1975, does not participate in the strong interaction, are leptons , but its heavy mass, PUR hot melt adhesive is 3600 times more electrons, protons 1.8 times, so called heavy leptons.
