Color change characteristics

Irreversible: The color never returns to original color after reaction.
Semi-irreversible: The color can return to original color by high humidity

Usage consideration

Apply qty: 80-100/1 m² by brush painting
Drying time: 4-5min at room temperature
Close the lid tightly and put in outer box after use. THERMOPAINT®R is flammable and volatile material. Store under dark, cool and well ventilated space
Use THERMOPAINT®No. within 1 year after purchase.
Clean apply surface well before use
Stir well with a thin stick before use since pigment is settled at the bottom of bottle.
Close the lid tightly and put in outer box after use. THERMOPAINT®R is flammable and volatile material
Semi-irreversible products arenot adequate for multipe use.

About us

"From the Ocean to Outer Space"

NiGK Corporationwas fully financed and established by NOF CORPORATION in December 1980. Inheriting the know-how accumulated by TEIKOKU PYROTECHNICS MANUFACTURE CO., LTD., which had lasted from 1938 to 1970, and that of NOF CORPORATION, Kawagoe Plant which succeeded it, we have promoted research and development in various fields in parallel with manufacturing of pyrotechnics and temperature indicating materials and other products. With on ever-expanding scope of our business, our products have been patronized in different fields widely ranging from the deep seabed to outer space, as indicated by our catch phrase, ""From the Ocean to Outer Space,"" contributing to safety and reliability of various systems.
