Yumingjie Technology specializes in producing a wide range of reflective materials, including main pigments, reflective powders, copper powders, luminous powders, phosphors, pearl powders, aluminum silver pastes, and glitter powders. These products are made from high-quality glass microbead powder materials, offering excellent retroreflective properties. They serve as core components for reflective fabrics, foils, coatings, signs, advertising materials, apparel, standard stadium tracks, footwear, accessories, school bags, and life-saving equipment for both land and water.
What makes these materials stand out is their strong retroreflective effect, which requires no external power source. This makes them ideal for use in road markings, ports, mines, firefighting, and other safety-critical environments. Their ability to reflect light back to its source significantly enhances visibility and user safety.
**Key Features of Yumingjie Reflective Powder:**

5. **Transparency:** ≥95%
6. **Roundness:** ≥93%
7. **Performance:** High resistance to oxidation, heat, and excellent reflective performance
**Application Methods:**
- **Water-Based Screen Printing Method 1:** Mix the reflective powder directly into transparent pulp with appropriate additives.
- **Water-Based Screen Printing Method 2:** Add the reflective powder to gold-silver powder binder and adjust for even application.
- **Water-Based Screen Printing Method 3:** Combine the powder with water-based "reflective powder special ink" and add 0.5–2% of a special catalyst for optimal results.
- **Oil-Based Screen Printing Method 1:** Mix the powder with varnish and adjust for smooth printing.
- **Oil-Based Screen Printing Method 2:** Incorporate the powder into ink or paint to create reflective ink, suitable for fabric, license plates, house numbers, and traffic signs.
For best results, keep the printed layer thin (30–50 micrometers) to allow the powder to partially expose on the surface. Adjust particle size according to the desired reflection effect.
**Construction Method (Spraying):**
1. Clean the surface thoroughly, removing oil, water, and dust, and ensure it's dry.
2. Apply a primer first, then spray the reflective topcoat once the primer is dry. For cement surfaces, applying two layers of primer is recommended.
3. Use a W-71 spray gun (nozzle size 1.50 mm), with a pressure of 2.0 kg/cm² for the primer and 3.0 kg/cm² for the topcoat.
4. Maintain a thin and uniform coating of about 20 micrometers for maximum reflectivity.
5. Keep the spray gun at a 45° angle and 18 cm away from the surface. Test on unknown substrates first.
6. Clean tools with thinner after use.
7. Avoid working in rainy, foggy, or snowy conditions, as this may affect adhesion and durability.
**Notes:**
1. Ensure the surface is clean, dry, and free of oils before application.
2. Mix the reflective primer and topcoat evenly before use. Stir continuously during application to prevent sedimentation of the powder.
