SPECOTIN coatings for moulds and cores

Composition: Some substantial differences exist with regard to impact on casting. Therefore, each SPECOTIN type is based on a main raw material, which has the best properties for the respective purpose; an optimum isolating effect is thus achieved between the mould, cores and metal. The main raw materials include: zirconium, graphite, coke dust, aluminium and magnesium silicates. In addition to the main raw materials, substances are used that give the coatings their particular property.

Application: Primarily for flow coating, immersing, spraying or brushing. Suitable for moulds and cores made of all mould materials.

Properties: The coatings produce smooth, abrasion-resistant and crack-free coatings with very good adhesion on sand substrates of every kind. They can therefore be used on all moulding and core sands.

Use: Although the coatings settle very little, it is nonetheless advisable to stir them before use. After the coating has been applied the cores and moulds can be fired after approx. 1 minute. Casting can begin around 2 hours after firing.

Packaging: disposable hobbocks, lidded drums, returnable containers.

Water-based coatings particularly recommended for light metal casting:

SPECOTIN 319 PT 1, Basis: Aluminium silicates with oxide fraction
SPECOTIN 319 PT 3, Basis: Aluminium silicates with oxide fraction
SPECOTIN 3149 PT, Basis: Aluminium and zirconium silicates with oxidants

Alcohol-based coatings particularly recommended for light metal casting:

SPECOTIN 352, Basis: Graphite
SPECOTIN 353 T, Basis: selected magnesium silicates with oxide fraction
SPECOTIN 35520, Basis: selected silicates, oxide fraction and graphite
SPECOTIN 359 A, Basis: Aluminium oxides
SPECOTIN 359 PG 5, Basis: selected aluminium silicates and graphite
SPECOTIN 35320, Basis: Magnesium silicates, graphite and oxide

A large number of other coatings are available on request.

SPECOTIN thinner

Characteristics: SPECOTIN thinner contains isopropyl alcohol

Properties: Thinner for all alcohol-based coatings

SPECOTIN mould and core varnish

Characteristics: Special varnish for surface hardening

Casting ladle coating

SPECASTIN LS 613 is an isolating coating for casting ladles. It forms a protective layer between the tool and liquid aluminium.

SPECASTIN LS ladle coating should be used instead for high sodium modification.

Application: brushing, spraying, immersing
Packaging: 5 kg, 10 kg, 20 kg tub
