Adhesives for the foundry industry
Gargi Hüttenes-Albertus has been supplying foundries with a wide variety of adhesives for many years. These are adhesives for cold and hot curing applications, as well as for curing in the microwave.
In the field of cold and oven curing, adhesives are mainly used, the main components of which are special water glasses and inorganic fillers. As a result, these adhesives release almost no gases when heated and are therefore preferably used for bonding critical core packages.
A wide range of adhesives with different properties is also available for special applications. For example, materials in the form of flakes for application over larger dosing tanks are a completely new addition to the product range.
Another current project is the development of a special hot melt adhesive for the lost foam process.
Glue applicators and sticks
Numerous qualities are also available in the form of sticks, which can be applied with the aid of suitable applicators. The air-operated applicator shown here has a storage magazine for quick change of the sticks.
A wide variety of applicators are available for the respective application.
Hot-melt adhesive | Adhesive based on polysaccharides, curing by oven drying, especially for hot box and cold box moulding materials in use.
|
Cold-melt adhesive | Adhesive on the basis of water glass in different viscosities, universally applicable, curing in air, to accelerate by heating.
|
Fast-adhesive | Adhesives that cure quickly due to low-volatile solvents.
|
Special-adhesive | Hot melt adhesive for assembly purposes, special sealing compounds.

Parting and Cleaning Agents
Parting and Cleaning Agents for the foundry industry
Parting & Cleaning agents are used to facilitate the moulding process significantly by effectively reducing the adhesive forces that hold the mould or core to the pattern/corebox. This simplifies the manufacture of sound moulds and cores and Improves working life of the pattern/corebox/die.
Parting Agents
Parting agents for all mould and core making processes:
- bentonite-bonded green sand
- acid curing phenolic and furan resin moulding sand
- ester curing phenolic resins (e.g. Alpha-Set process)
- inorganic binder systems
- gas curing moulding materials (Cold-Box, Beta Set, waterglass-CO2 and ester processes)
- moulding sands cured in hot coreboxes (Hot-Box and Shell Moulding process)
Cleaning Agents
Gargi HA offer special cleansing agents for organic resin deposited on patterns.
- It removes depositation of uncured / partially cured resins like Alkyd Phenolic urethane Resins and other organic binder resins which are employed to make cores and moulds for casting/ foundry industry.
- It loosens the resin deposit on pattern without affecting pattern quality and dimensions. It is a blend of volatile liquids which is partially soluble in water and slightly acidic in nature.
