Heat resistance and thermal insulation

Outline

Heat resistant coatings produced by blending Alpaste® with inorganic binders exhibit heat resistance above the melting point of aluminium (660°C), as the aluminium reacts with the steel base material and oxygen, etc.

Alpaste® is shaped into thin flakes, so it has excellent heat reflection properties and protects the internal parts from high temperatures. Leafing Alpaste® exhibits high reflection properties because it floats to the surface of the coat, so it is ideal for heat resistant coatings. Stainless steel flakes should be considered for heat resistant coatings to be exposed to even higher temperatures and highly corrosive environments.

Thermal insulation coatings that suppress the rise in temperature inside buildings and vehicles have been attracting attention recently from the viewpoint of energy saving. Alpaste® and stainless steel flakes have excellent infrared reflection properties, so they can be expected to have excellent effects as pigments for thermal insulation.
