Potassium Silicate in Floor Coatings

Potassium silicate is commonly used in the manufacture of welding rods, welding electrodes, vat dyes, and fire retardants, as well as in fluorescent screen coatings and as a soap filler. In addition, the field of floor coatings is also an important stage where potassium silicate demonstrates its utility. For more details, please allow Worner, a professional manufacturer, to introduce them to you.

I. Introduction to the Basic Properties of Potassium Silicate

At room temperature, potassium silicate solution typically appears as a colorless or slightly yellow, translucent to transparent, glassy viscous liquid, while high-purity crystals appear bluish-green. Potassium silicate is hygroscopic and produces a strong alkaline reaction; it decomposes in acids, precipitating silica. It is readily soluble in water and acids, forming a colloidal silicic acid precipitate. The higher the potassium content, the more soluble it is (note: it is insoluble in alcohols).

II. Application of Potassium Silicate in Concrete Sealing and Hardening Agents

Concrete sealing and hardening agents, also known as penetrating liquid hardeners, are widely used in the construction industry as concrete sealants, hardeners, and dustproofers. They are commonly applied in workshops, underground garages, and similar settings, serving as an important method for creating high-strength, dust-free, and impermeable floors. Among these, the “potassium-based concrete sealing and hardening agent” is a type of floor coating formulated using “potassium silicate concentrate” as the primary binder, combined with certain polymer materials, additives, and fillers.

The “potassium-based concrete sealing and hardening agent” represents the second-generation production process for hardening materials. It features fast drying speed and demonstrates good performance in terms of crack resistance, dispersibility, high modulus dry strength, initial water resistance, anti-settling properties, and spray flowability. In practical applications, the potassium-based material effectively penetrates and reacts with free calcium oxide in the concrete to form a sturdy silica sol, thereby making the concrete structure denser, impermeable, wear-resistant, and robust. After treatment with a floor grinder, it achieves a finish that is as hard as steel and as glossy as a mirror.

As a fundamental type of hardening material, the “potassium-based concrete sealing and hardening agent” meets the basic hardening and finishing needs of property owners. It effectively enhances the mechanical properties of cement-based floors (hardness, wear resistance, density, etc.), achieving the effects of hardening, dustproofing, sealing, and impermeability.
