Sodium / Potassium / Lithium Silicate | Mohs 7-9 | 20+ Years Service Life
Concrete Hardening Materials | Concrete Densifier & Sealer
Product Overview
Ordinary concrete is prone to dusting, oil staining and rapid wear. Concrete densifier and hardener reshapes floor performance at the material level — its core components (sodium silicate, potassium silicate and lithium silicate) penetrate deeply into the concrete and react chemically with free calcium and magnesium ions to form water-insoluble hydrated calcium silicate gel (C-S-H gel). This gel fills the pores and binds the aggregate particles, converting the floor from a “loose sponge” into a “dense rock”. One application delivers long-term durability.
Zhongheng supplies all three mainstream silicate chemistries so buyers can match the product to the floor type, traffic load and budget rather than over- or under-specifying. Each grade is supported with application review, private-label presentation and order-based configuration while keeping unverified performance claims out of the specification.
Key Features
- Super wear-resistant — Mohs hardness of 7–9 withstands heavy traffic with minimal scratching
- Completely dustproof — seals surface pores, stops sanding and dramatically raises cleanliness
- Water and oil resistant — water and oil cannot penetrate, stains wipe away easily
- Durable — modifies the internal structure, prevents peeling and cracking, service life exceeds 20 years
- Eco-friendly — formaldehyde-free and odorless, ready for use immediately after completion
- Three chemistries available — sodium, potassium and lithium silicate grades for different project levels

Customization Options
Silicate chemistry, concentration, packaging size, label artwork and private-label presentation can be reviewed for OEM/ODM programs. Final choices depend on technical feasibility and confirmed order requirements.
Packaging & Shipping
Products can be packed with protective inner separation, grade and batch labels, then placed in export cartons or drums. Carton and drum marks, barcode labels, neutral packing and private-label packaging can be arranged. Shipment mode and outer packing are confirmed according to order quantity, destination and buyer instructions.
Manufacturing & Quality Control
Production control focuses on incoming raw material checks, concentration verification, batch consistency, visual inspection and order traceability. Grade and batch labels are checked before packing. Application samples can be evaluated before volume production when compatibility or finish requirements need validation.
FAQ
What is the difference between sodium, potassium and lithium silicate?
Sodium silicate is the most economical grade with fast penetration for basic dustproofing. Potassium silicate offers balanced performance and resists efflorescence, suiting commercial corridors and offices. Lithium silicate achieves the deepest penetration and highest hardness with no efflorescence, making it the choice for food, electronics and premium hospitality floors.
How does the hardener actually work?
The silicates penetrate the concrete and react with free calcium and magnesium ions to form water-insoluble C-S-H gel. This gel fills the capillary pores and binds the aggregate, densifying the surface rather than coating it.
How long does the floor last?
Once fully cured, the hardened floor is specified for a service life exceeding 20 years under normal traffic, without repeated repairs or waxing.
Is it safe for food and electronics environments?
The formulation is formaldehyde-free and odorless, and is ready for use immediately after completion. Lithium silicate grade is typically specified for food processing plants and electronics factories.
Can the floor still effloresce?
Efflorescence resistance depends on the grade. Potassium silicate is balanced for low efflorescence, while lithium silicate is specified as no efflorescence.
Do you offer OEM or private-label supply?
Yes. Chemistry, concentration, label artwork, carton graphics and distributor packaging can be reviewed for OEM/ODM orders.
What information is needed for a quotation?
Please provide the required grade (sodium / potassium / lithium silicate), quantity, packaging request, private-label requirements if any, and destination country.
