Glass-like carbon coated GLASTIX KOTE™

Catalog
Download Products Inquiry

GLASTIX KOTE™ is a material impregnated or coated with glass-like carbon on a graphite or neighboring surface.
It enables use of various Toyo Tanso graphite materials as a substrate, and it does not lose its substrate properties.
Not only does this material offer enhanced durability against scratching and other friction, it also reduces the generation of dust.

Features

Able to use various Toyo Tanso graphite materials as a substrate.
Does not lose graphite substrate properties.
Able to reduce the generation of graphite powder.
Enhanced durability against scratching and other friction.

Application

Parts for silicon single crystal pulling devices
Parts for epitaxial growth
Dies for continuous casting
Glass sealing jigs

Properties/Test Data

General Physical Properties

* Example of physical properties when using ISEM-3 as a graphite substrate and applying GLASTIX KOTE™ GP series processing.
(Rate of change with measured value of ISEM-3 substrate as the standard)
Test piece dimensions:
10x10x60 mm: Bulk density, hardness, electrical resistivity, flexural strength
10x10x10 mm: Compressive strength

Dust Reduction Effect

GLASTIX KOTE™ processing can greatly reduce the amount of carbon dust generated.
* This is the result of measuring the number of fine particles in the cleaning solution.

Scratch Strength Comparison

The durability against scratching with GLASTIX KOTE™ processing nearly doubled, and a similar improvement in wear resistance can be expected.
* Critical load indicates the vertical load when the surface begins to show damage.
