- One-component urethane adhesives and urea adhesives cure more slowly than epoxy adhesives, and have slightly lower adhesive strength.
- these adhesives have the disadvantage that many combustion residues remain when burned. If there are many combustion residues in the adhesive used in the manufacture of the disappearance model for forging, when the porcelain is manufactured using the disappearance model for forging, the combustion residue enters the interior of the object or adheres to the surface. Cheap. If the combustion residue enters the inside of the porridge or adheres to the surface, the strength of the porcelain is reduced or the workability is deteriorated. Therefore, the generation of this combustion residue has been a problem especially when manufacturing high-precision products such as automobile and ship engines and precision machine tools.
- the inventors of the present invention have been concerned with some of the combustion residues of adhesives such as two-component epoxy-based, one-component urethane-based, and urea-based adhesives that have been conventionally used in the production of polystyrene foam foam-disappearing models. investigated.
