Night Vision Epoxy Grout is a specialized type of tile grout that includes phosphorescent (glow-in-the-dark) materials. It's designed to absorb light during the day or under artificial lighting and emit a glow in low-light or dark conditions, making it useful for both functional and aesthetic applications.
Here are the key details:
🔹 What Is Night Vision Epoxy Grout?
Night Vision Epoxy Grout is a two-component epoxy-based grout that includes a phosphorescent pigment (typically strontium aluminate-based), allowing it to glow in the dark after being charged by a light source.
🔹 Key Components
Epoxy Resin – Provides durability, chemical resistance, and water resistance.
Hardener – Reacts with resin to cure and harden the grout.
Phosphorescent Pigments – Absorb and store ambient light, then emit a soft glow in darkness.
