Graphite I 75 L is our standard product. It is a powder made on the basis of graphite and other carbon and mineral materials.
The specific gravity is about 0,5 kg/l.
Packaging:
Powder in multi-layer paper-bags with a net weight of 40 kg.
Application:
Graphite I 75 L is used as an immerse product (dip-product) applied with the foundry of brass after the techniques of manual,
mechanical and low pressure.
Graphite I 75 L is also suitable for lead-free brass casting.
Treatment:
Graphite I 75 L is mixed in water in the proportion of 1 to 5 and is at once ready for use.
The proportion can be changed according to the weight and thickness of the sides.
Graphite MS or MS 50 G can in special cases be added to Graphite I 75 L. Thus the covering power and sliding ability can be improved.

Bearing application:
In dry rooms Graphite I 75 L is indefinitely imperishable.
Effect:
Longer durability of the die
More castings before a cleaning of the permanent mould becomes necessary
Improvement of output and productivity through a better liquid flow of the metal
Uniform surface of the castings
Less subsequent after work of the casting
Reduce hot cracking tendency.
Responsibility of characterization:
According to the German regulations about dangerous materials this material need not be particularly characterized.
The preceding data are in accordance to our present knowledge and experiences.
