Luminescent material particle size on coating application

Luminescent material particle size on coating application and the luminous intensity has a great influence . If the luminous powder particle size is large, the paint easy precipitation , distributed unevenly affect workability , glow powder suppliers ; if the particle size is too small luminous powder , luminous nature may be destroyed, afterglow time is not long lasting. However, coating processing performance, the luminous powder particle size finer the better , preferably greater than 360 mesh . Luminous powder dosage on the coating properties also have a great impact , luminous powder with less, its total luminous intensity is weak , with the increasing amount of luminous powder , coating significantly increased brightness , but the luminous glowing stone pebbles a certain amount , the then light emission luminance of stable coating . In addition, the luminous powder expensive, its excessive use , will increase the cost of paint . Based on the above considerations, luminous powder dosage of 10% to 20 % is appropriate.
