FAQ

Mechanism of Luminescence:

• Photoluminescent Pigment: Absorbs photons and slowly releases them, creating a glow. This process is repeatable with periodic exposure to light.

• Radioluminescent Materials: Glow when exposed to radioactive materials, exciting the phosphor compound. Example: tritium in watches and exit signs.

Safety:

• Photoluminescent Pigment: Generally safe, containing no radioactive materials and requiring no electricity.

• Electroluminescent Materials: Generally safe but require electrical power, posing shock risks if mishandled.

Applications:

• Photoluminescent Pigment: Common in safety signs, watches, toys, paints, and crafts for its safety and ease of use.

• Radioluminescent Materials: Limited use due to safety concerns, found mainly in military, aviation, and specialized watches.

• Electroluminescent Materials: Used for backlighting, signage, and decoration, offering uniform light sources.

Duration and Intensity of Glow:

• Photoluminescent Pigment: Glow duration varies from minutes to hours, diminishing gradually after light exposure.

• Radioluminescent Materials: Glow continuously with active radioactive material.

• Electroluminescent Materials: Glow continuously with supplied electrical current, offering control over intensity and duration.

Yes, photoluminescent pigment/powder can be incorporated into water-based applications, provided specific considerations are met to ensure effectiveness and durability in such environments. Typically composed of inorganic materials, photoluminescent pigments are not inherently soluble in water. However, they can be suspended in water-based mediums with proper formulation and compatibility.

The charging and glowing process of photoluminescent pigment/powder is directly influenced by exposure to light. This process operates on the principle of photoluminescence, where the pigment absorbs photons (light particles) and then re-emits them, resulting in a visible glow.

1. Keep in a Cool, Dry Place:

• Temperature: Store the pigment in a cool environment to prevent degradation.

• Humidity: High humidity can cause clumping and affect dispersion. Use airtight containers to shield from moisture.

2. Use Airtight Containers:

• Store the pigment in sealed containers to prevent moisture and contamination.

3. Avoid Physical Contamination:

• Ensure storage containers are clean to prevent cross-contamination. Use dedicated utensils for handling.

1. Base Material Compatibility:

• Consider the compatibility of the photoluminescent masterbatch with the base material used in your application. Ensure that the masterbatch is designed to work effectively with the specific material, whether it's plastic, paint, rubber, or another substrate.

• Verify compatibility through testing or consulting with the masterbatch manufacturer to confirm that the formulation is suitable for your chosen base material.

2. Color and Aesthetics:

• Choose a photoluminescent masterbatch that aligns with your desired color and aesthetic requirements for the application. Masterbatches are available in various colors and shades, allowing you to match the luminescent effect with your product's design or branding.

• Consider factors such as glow intensity, duration, and color consistency under different lighting conditions to achieve the desired visual impact.

3. Processing Conditions:

• Evaluate the processing conditions required for incorporating the photoluminescent masterbatch into your manufacturing process. Ensure compatibility with existing equipment and procedures, such as injection molding, extrusion, or painting techniques.

• Opt for a masterbatch formulation that offers ease of handling and uniform dispersion within the base material to minimize production challenges and maintain product quality.

4. End-Use Environment:

• Assess the intended environment and application requirements to determine the suitability of the photoluminescent masterbatch. Consider factors such as exposure to UV light, temperature extremes, moisture, and mechanical stress.

• Choose a masterbatch with properties that meet the durability, weatherability, and performance standards needed for the specific end-use environment, whether it's indoor signage, outdoor safety markings, or consumer products.

5. Safety and Regulatory Compliance:

• Prioritize safety considerations when selecting a photoluminescent masterbatch, especially for applications involving direct contact with consumers or compliance with industry regulations and standards.

• Ensure that the masterbatch meets relevant safety guidelines, such as REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) regulations or ASTM (American Society for Testing and Materials) standards, to guarantee product safety and regulatory compliance.
