There are four main factors affecting the reflection coefficient of customized reflective hot melt marking paint in china:

Factor 1: laying the foundation for the brightness factor of customized reflective hot melt marking paint in china

The brightness factor of hot-melt coating directly affects the retroreflection coefficient of the marking. Too little resin and titanium dioxide with deep color number will affect the brightness factor. In addition, add whitening agent: for example, adding blue series pigments will increase the perceived whiteness, but will affect the brightness factor.

Factor 2: the selection of micro beads of customized reflective hot melt marking paint in china is very important

The roundness rate of micro beads directly affects the retroreflection coefficient (micro beads with roundness rate of more than 80% shall be selected as far as possible), and the size of micro beads will affect the retroreflection coefficient.

Factor 3: the construction temperature control of customized reflective hot melt marking paint in china is the key

The construction material temperature will affect the retroreflection coefficient. Control the material temperature and ensure that 50% - 60% of the micro beads are embedded in the marking coating. At this time, the effect is good.

Factor 4: the micro beads of customized reflective hot melt marking paint in china shall be evenly distributed

Too much or too little spreading will affect the retroreflection coefficient of the marking, and the appropriate amount should be about 0.35kg/m2.

It is suggested that in order to ensure that the retroreflection coefficient of customized reflective hot melt marking paint in china is qualified, please select the paint with high brightness factor and large particle beads with high roundness rate. At the same time, pay attention to the uniformity of bead distribution and control the construction temperature!
