Adhesives for molds and cores
The products of this group are widely used in foundries. They are used for permanent binding, sealing or repair of molds and cores. Proper selection of the right adhesive has a fundamental impact on the quality of the castings produced.
Hüttenes-Albertus has appropriate adhesives for various types of applications and at the same time new products are developed according to the needs of customers.
HA products can be divided into four groups due to the type of application and chemical composition:
Cold hardening adhesives (Kaltkleber) adhesives based on water glass of various viscosities, universal, hardened in air or by heating, which accelerates the curing process.
Hot-hardened adhesives (Heißkleber) polysaccharide-based adhesives, hardened by drying, used especially for hot-box and cold-box sandwich materials.
Adhesives for shell forms (Maskenkleber) adhesives based on thermally hardened synthetic resins, curing reaction proceeds analogously to the Croning process, designed for such processes as hot-box.
