Water-based Adhesive

Water-based adhesive is freezing process containing a certain amount of wax and plastic to enlarge temperature range of de-binding. In order to prevent deformation, it is best to adopt freeze drying method for de-binding. One method is adding a lot of ethyl silicate. Those silicate glass gel can form solid structure at frozen temperature and carbon dioxide atmosphere, which helps to rapid drying de-binding. But silica cannot be removed and will remain in stock finally.

Ttherefore material can allow for the possibility of silica.
