Our products feature customizable modulus and concentration, fully meeting large-scale industrial production and agricultural planting demands for clients who purchase bulk liquid potassium silicate with strict quality requirements.

This industrial liquid potassium silicate is produced through high-temperature fusion, precise proportioning, water dissolution and multi-stage purification filtration processes. It presents a clear and uniform liquid state with zero precipitation, low impurity content, excellent water miscibility and stable chemical activity. Free of heavy metal and harmful residues, it is a high-quality foundational inorganic raw material suitable for diverse industrial and agricultural production scenarios.

Introduction to Liquid Potassium Silicate

Commonly referred to as liquid potassium water glass, liquid potassium silicate is a liquid water glass product formed by melting silica sand and potassium carbonate at high temperature, followed by water dissolution and refined purification treatment. Unlike solid silicate products, it requires no grinding or heating dissolution, supporting direct dilution and on-site use with extremely convenient operation, transportation and storage.

Under standard room temperature and atmospheric pressure, liquid potassium silicate appears as colorless or pale yellow transparent homogeneous liquid, featuring outstanding bonding strength, excellent permeability, high-temperature resistance, corrosion resistance and gelling performance. With stable alkalinity and strong chemical reactivity, it boasts wide compatibility with surfactants, inorganic fillers and chemical additives.

Serving as high-quality liquid potassium silicate fertilizer raw material, our liquid potassium water glass is non-toxic, pollution-free and highly water-soluble, requiring only simple dilution for direct use.

Liquid Potassium Silicate 2.5-2.6 Modulus Application

Our high-stability liquid potassium silicate (liquid potassium water glass) features superior bonding, permeable curing, high-temperature resistant and plant nutrient regulation properties. It is mainly applied in four core fields: agriculture, industrial coatings, concrete flooring and welding electrode manufacturing. Detailed application scenarios are as below:

• Agriculture Industry (Liquid Potassium Silicate Fertilizer Application)

As a professional liquid potassium silicate fertilizer raw material, it is a high-efficiency soluble silicon and potassium supplement for modern crop planting. After simple dilution, the liquid potassium water glass can be used for foliar spraying and root irrigation for various crops. It effectively thickens crop cell walls, significantly improving lodging resistance, drought resistance, high-temperature tolerance and disease resistance of plants. In addition, it optimizes crop photosynthesis, promotes nutrient absorption, boosts fruit yield and improves crop quality. With low impurity and non-toxic formula, it is a safe and efficient functional fertilizer auxiliary for grain crops, vegetables, fruits and economic crops.

• Industrial Coating Industry

Liquid potassium silicate is a core environmental-friendly raw material for manufacturing inorganic fireproof coatings, high-temperature resistant coatings and water-based industrial coatings. It has excellent film-forming performance and substrate adhesion, which can greatly improve the hardness, weather resistance, abrasion resistance and flame retardancy of coating layers. Different from sodium silicate coating materials, potassium silicate liquid features better water resistance and less efflorescence, effectively avoiding coating cracking and powder falling. It is widely used for architectural fireproof coatings, industrial equipment high-temperature anti-corrosion coatings and inorganic functional coating production.

• Concrete Flooring Industry

Serving as a key penetrating curing agent and floor hardener for industrial concrete floors, liquid potassium silicate features strong permeability and chemical reactivity. It can penetrate deep into the internal pores of concrete, react with free calcium hydroxide and cement hydration products to form dense insoluble crystalline substances. This process effectively seals concrete pores, significantly improving floor density, surface hardness, abrasion resistance, anti-permeability and dust-proof performance. It is widely applicable for factory workshops, warehouse floors, supermarket ground and industrial infrastructure concrete reinforcement and hardening treatment.

• Welding Electrode Industry

Liquid potassium water glass is an indispensable high-performance binder for welding electrode and welding rod coating production. It features stable viscosity, strong bonding force and excellent high-temperature resistance during electrode baking and welding processes. It can firmly bond various mineral powder coatings on the steel core surface, preventing coating peeling and cracking. During welding, it forms a stable protective slag layer, effectively isolating air, reducing welding spatter, stabilizing electric arc and improving welding seam quality. It is the preferred inorganic adhesive material for high-quality industrial welding electrode manufacturing.
