Résumé : |
The study shows that by manipulating the polymer structure, it is possible to produce polyether polyol-based polyurethane reactive hot melt adhesive systems with green strengths, viscosity and melt stability properties comparable to polyester polyol-based systems.
Melt stability is affected by the final NCO content of the prepolymer and the temperature of application. Higher index allows for lower application temperatures, which is considered a desirable feature by the adhesive user due to industrial hygiene concerns.
For the purposes of this study, tack free times were faster than what is normally expected, but it should be noted that this work was carried out on prepolymers without any further formulation additives. The adhesive manufacturer can manipulate this variable to some extent by using tackifiers. |
