Hot melt pressure sensitive adhesive compositions have been described, based on lactic acid polymers (37-39). However, such compositions have been claimed to be not suitable for the fields of food packaging as they have the drawbacks of being rather stiff and having a heat-reactivation temperature that is too high for food packaging applications (35). Hot melt compositions are shown in Table 7.8. 

The formulations given in Table 7.8 are representative of hot melt adhesive compositions with open assembly times of greater than 2 s, which makes them suitable for the application on rigid supports such as standard cardboards. The hot melt compositions can be prepared by simple mixing its components at a temperature of 100-200°C, until a homogeneous mixture is obtained.

Polywax 1000 was used as nucleating agent in an isocyanate free UV curable hot melt composition. The coating is particnlarly useful in wood-working and furniture applications. ... 

Caulks and sealants made from the isobutylene polymer family are available in three forms. As bulk sealant materials, they are usually one-part, plasticized systems, compounded with suitable inert fillers and solvents and designed for application with a standard caulking gun. As preformed tapes or ribbon sealers, they are 100% solids, tacky materials, supplied in roll form on a release paper backing and designed for easy hand application in areas which usually require compressive confinement for an effective seal. Finally, in a newer format as 100% solids, hot melt compositions, they are specif-...
