With the development of industry and the adhesive required for bonding between dissimilar materials, the demand for increasingly growing trend. Improvement of the work environment, especially in the bonding process and labor-saving and automation of work processes in terms of the importance of the hot-melt adhesive is largely emerging. Hot-melt adhesive is cured after application to the time it takes only a few seconds is not a very fast cure speed and therefore has a great advantage as standing industrial solvent-free adhesive to minimize the impact on the work environment can be an advantage to have. However, a high temperature and the working environment is sensitive to heat and cold also has the disadvantage of difficult coexistence. Therefore, such problems and to maintain the adhesive properties of the continuous development of the reactive hot-melt adhesive is an adhesive expand the scope of application of the chair. |
