PUR hot-melt adhesive -PUR1075

PUR hot melt adhesive product introduction

PUR (PolyurethaneReactive), is moisture curing reactive polyurethane hot melt adhesive. The main component is isocyanate polyurethane prepolymer.Molecular structure containing polar and chemically reactive ammonia ester group (-NHCOO-) or isocyanate group (-NCO). For wood, metal, glass, rubber, plastic, leather, fabric, paper and other materials have a good adhesion. PUR hot melt adhesive has been used in Europe for decades, the technology is mature, today is still the best adhesive in many fields. Pur hot melt adhesives in the use of the process with physical and chemical reaction of two process: physical response as with ordinary hot melt adhesive thermal plastic cold solid performance and coating in high temperature liquid state, laminating cooling after rapid crystallization orientation; chemical reaction is in fit after about a few hours to a few days and pur reactive groups and active hydrogen chemical crosslinking into polyurethane polymer. Pur hot melt adhesive cured polyurethane rubber, adhesive strength, solvent, resistant paint, heat resistance, hydrolysis and other performance is obviously better than that of EVA hot melt adhesive, water or solvent type glue water. Pur hot melt adhesive for 100% of the active ingredient, no any water or solvent volatilization, comply with the the highest levels of environmental standards, its the most green .

Product advantages of PUR hot melt adhesive

  1. Does not contain any organic solvents, solid content 100%, green;
  2. Moisture curing, no drying process, quick energy;
  3. Excellent initial strength, but also has the function of crosslinking, the higher the final bond strength;
  4. Excellent heat resistance, water resistance, chemical resistance, durability and etc;
  5. One-component type, easy to industrial automation, mechanization operation, high production efficiency.
