PHOTOLUMINESCENT POWDER INTRODUCTION

PHOTOLUMINESCENT POWDER INTRODUCTION

Photoluminescent powder, also known as pigment, is a non-toxic, non-

radioactive new environmentally friendly alkaline earth aluminate pigment. Most of the visible or UV light will charge the pigment particles (excitation).

The photo luminescent pigment then releases energy for 10 to 24 hours in the form of visible light (which glows in the dark). The photographic light-

emitting pigments provide duty-cycle operation with a very high ratio of glow time to the desired charging time. Luminous intensity (brightness) and

afterglow time than the traditional ZnS (zinc sulfide) or usually sold retail store products more than 30 times higher.

Photoluminescent Powder Characteristics

• Safe for normal uses as it contains no radioactive or toxic materials.

• Long glow time. Compared with previous photo storage materials, it has up to 50 times longer emission (glow) time.

• High initial brilliance. Initial luminance of up to 40,000 mcd/m2.

• High durability. Long shelf life if the crystalline structure is not damaged.

• Outdoor usage. Suitable for outdoor usage as it does not suffer luminance reduction even when placed under a 300-watt high-pressure

  mercury lamp for 1000 hours.

• Stable Chemical Reaction. Not-encapsulated powder is stable as it is resistant to most anhydrous chemicals, both organic and

  inorganic. However, it will decompose into metal oxide and lose its luminance when brought into contact with water. Waterproof powder should be used for high

  water content mediums such as kids water paint. Most resin, epoxy, silicone and acrylic paints can be used with our not-encapsulated pigment and brighter

  pigment.
