Our night reflective spray contains phthalimide, polydimethylsiloxane. It can prevent nighttime travel hazards by reflecting light at night, without damaging the substrate, and ensuring that the appearance and color of the item do not change. The method of use is very simple: clean the oil, dust and water on the surface of the object to be sprayed, shake up the spray, and spray it evenly 20-30cm from the object surface. It can be used as a luminous warning to prevent the danger of traveling at night.
