Special reminder

In order to obtain good performance, additives must be added to the grinding material first, and then the pigment. In coatings based on nitrocellulose, chlorinated rubber and PVC copolymer, the additive may cause discoloration. In the silicate coating, the construction time limit will be shortened. High dosage may affect the construction time limit and curing of epoxy system.
