What is the best method for applying reflective powders?
Reflective powder can be directly added into coatings or resins to achieve retroreflective effects. It can be applied on complex surfaces. It is a core raw material in production of new optical composite materials, such as reflective cloth, reflective films, reflective coatings, reflective signs, advertising materials, clothing materials, standard racetracks and so on. Hereby pls check some method for applying reflective powders as follows; Water-based silk screen printing Reflective powder can be directly added into reflective paste and transparent paste.It can be mixed for stamping and printing. Oil-based screen printing 1: Reflective powder can be directly added into varnishes.It can be mixed for stamping and printing. 2: It can be directly added into inks to produce reflective ink.It can be easily screen printed or brushed onto fabrics or other items. 3: First, apply one layer of stamping primer.Then, apply one layer of reflective paste, followed by drying and curing. Depending on the dosage, weigh reflective powder and add it into cyclohexanone to prepare the paste.Then, mix it with transparent stamping paste.In the printing process, the adhesive layer should be 30-50 microns in thickness, so that reflective powder is semi-exposed on the surface to produce a reflective effect.Or, the particle size may be selected based on applications to achieve various reflective effects.Unequal particle sizes will lead to better reflective effects. Spraying 1. First, spray the reflective primer.When the reflective primer is dry, spray the reflective topcoat.It is recommended to apply two layers of reflective primer on cement surfaces. 2. It is recommended to use a W-71 spray gun with a nozzle of C1.50mm.The spray gun pressure should be approximately 2.0kg/cm2 for primer and 3.0kg/cm2 for topcoat. 3. The spray gun should be kept at a distance of 18cm away from the surface and an angle of 45 degrees during construction.The paint film should be evenly thin to achieve good effects. 4. Stop construction in case of rain, fog, and snow.Otherwise, the fastness may be affected.
