Liquid lithium silicate is a film-forming material and functional additive in the coating industry, which can provide long-term anti-corrosion, high temperature resistance, high water resistance and weather resistance. It is suitable for metal heavy anti-corrosion, construction, fire prevention, concrete protection and other scenarios, especially for harsh working conditions such as humidity, high temperature, and strong corrosion. The following are specific application and technical points:
Application scenarios and value:
1. Inorganic zinc rich anti-corrosion coating
Role: As a film-forming base material for water-based inorganic zinc rich primer, it forms a dense passivation film by compounding with zinc powder.
Performance advantages: Self drying without baking, coating with heat resistance up to 1000 ℃, salt spray resistance, dry wet alternation resistance, solvent resistance, and anti-corrosion service life of offshore engineering up to 20 years or more.
Typical applications: Long term heavy-duty anti-corrosion for ships, offshore platforms, oil pipelines, bridges, building steel structures, etc.
2. Interior and exterior wall coatings for buildings
Function: Enhance coating adhesion, water resistance, weather resistance, and stain resistance, suitable for humid environments and high water resistance scenarios.
Application scenarios: Wet areas such as bathrooms, kitchens, basements, swimming pools, etc; Exterior mineral coatings enhance aging and weathering resistance.
Technical proposal: It can be compounded with silica sol and lotion to improve toughness and workability and reduce cost.
3. Fireproof and high-temperature resistant coatings
Principle: A continuous SiO ₂ glassy coating is formed at high temperatures, providing thermal insulation, flame retardancy, and preventing substrate oxidation and degradation.
Application: Industrial kilns, chimneys, high-temperature pipelines, power equipment, etc., meet A-level non combustible and long-term heat resistance requirements.
4. Concrete and floor coatings
Function: Penetrating and solidifying the substrate to form a three-dimensional silicon oxygen network, improving hardness, wear resistance, and impermeability, and suppressing sanding and dust generation.
Application: Factory floor, parking lot, airport runway, concrete component protection, suitable for heavy-duty and high-frequency use scenarios.
5. Functional additives
Metal surface treatment: used as a conversion coating agent to enhance coating adhesion and corrosion resistance, suitable for substrates such as steel and aluminum.
Coating modification: improves water resistance, weather resistance, and corrosion resistance, used for water-based industrial paints, anti-corrosion topcoats, etc.
