Usage of Potassium Silicate
1. Welding Electrode Binder
Inorganic binder for welding electrode coating. Improves coating adhesion, stabilizes electric arc and slag property, widely adopted in welding rod manufacturing.
2.Agricultural Silicon & Potassium Fertilizer
Soluble silicon-potassium nutrient for foliar and root application. Strengthens plant cell wall, enhances stress resistance, disease resistance and lodging resistance for crops, fruits and vegetables.
3.Coating & Fire Retardant Additive
Film-forming auxiliary for inorganic coatings, wood fireproof treatment agent. Forms dense silica protective layer to block flame and moisture penetration.
4.Concrete & Hardener Auxiliary
Concrete densifier and surface sealing agent. Reacts with free calcium ion to improve surface hardness, wear resistance and anti-dust performance of cement floor.
