Vinyl Ester Anti-Corrosion Flooring System Manufacturer in China

The Vinyl Ester Anti-Corrosion Flooring System adopts a multi-layer reinforced coating process using vinyl ester resin and fiberglass fabric to achieve excellent chemical resistance and long-term durability in highly corrosive environments. Common application systems include Two-Fabric Three-Coat and Three-Fabric Five-Coat methods, depending on corrosion severity and service conditions.

Surface Preparation

Proper substrate preparation is critical to the performance of vinyl ester flooring.

• Mechanically grind the concrete surface to remove laitance, loose particles, cement nodules, and contaminants
• Ensure the surface is clean, dry, and free of dust, oil, or debris
• Substrate flatness requirement: ≤ 3 mm deviation over a 2 m straightedge
• Repair cracks, voids, and damaged areas prior to application

Two-Fabric Three-Coat System (Standard Heavy Anti-Corrosion)

1. Primer Application

• Mix vinyl ester clear primer with curing agent at a ratio of 100 : 1.2 (by weight)
• Apply evenly using roller or brush
• Purpose: strengthen the substrate, seal concrete capillary pores, and enhance adhesion
• Ensure the surface is dust-free before priming

2. Fiberglass Fabric Reinforcement (Two Layers)

• Mix vinyl ester clear resin with curing agent at 100 : 1.2
• Use the resin to bond fiberglass fabric to the substrate
• Apply two layers of fiberglass fabric as specified
• Ensure fabric is flat, fully impregnated, and free of air bubbles or blisters

3. Fine Sand Mortar Layer (One Coat)

• Mix vinyl ester flooring coating with curing agent at 100 : 1.5
• Add fine sand and apply using a steel trowel
• Ensure uniform texture, good compaction, and no sand shedding

4. Putty Layer (Two Passes)

• Mix vinyl ester flooring coating with curing agent at 100 : 1.5
• Add quartz powder or talc powder to form putty
• Apply two passes evenly
• After curing, grind and clean the surface
• Requirements: full coverage, no pinholes, no loose sand

5. Topcoat Application

• Mix vinyl ester topcoat with curing agent at 100 : 1.5
• Apply one uniform coat using roller
• Finish requirements: uniform color, consistent thickness, no roller marks, no bubbling, no pinholes, no orange peel

6. Curing

• Allow the flooring system to cure for at least 3 days to achieve optimal performance
• No traffic or mechanical load during curing period

Three-Fabric Five-Coat System (Severe Anti-Corrosion)

This system is recommended for extreme chemical exposure environments.

1. Fiberglass Fabric Reinforcement (Three Layers)

• Use vinyl ester clear resin mixed at 100 : 1.2
• Apply three layers of fiberglass fabric
• Ensure smooth bonding, no lifting, blistering, or air entrapment

2. Fine Sand Mortar Layer (Two Coats)

• Mix vinyl ester flooring coating with curing agent at 100 : 1.5
• Add fine sand and apply two passes
• Surface should be dense, even, and free of loose aggregates

3. Topcoat Application (Two Coats)

• Mix vinyl ester topcoat with curing agent at 100 : 1.5
• Apply two coats using roller
• Final surface must be smooth, uniform in color, and fully sealed

4. Curing

• Cure for minimum 3 days before service
• Restrict access during curing

Alternative System Configurations

Depending on project requirements, the vinyl ester anti-corrosion flooring system can be designed as:

• Two-Fabric Three-Coat
• Three-Fabric Five-Coat
• Five-Fabric Seven-Coat

Fiberglass fabric layers and intermediate coatings may be repeated to meet specific chemical resistance and thickness requirements.

Application Notes & Technical Precautions

• Each layer must be fully cured before applying the next layer
• Recommended application temperature: 5–35°C
• For temperatures outside this range, consult the manufacturer
• Pot life after mixing: Approx. 30 minutes in container and Approx. 40 minutes when spread on floor
• Higher temperatures reduce pot life significantly
• Application is not recommended above 35°C

Mixing Ratio (By Weight)

≤ 20°C

• Vinyl Ester Topcoat: Curing Agent = 100 : 1.5
• Vinyl Ester Clear Resin: Curing Agent = 100 : 1.5

20–30°C

• Vinyl Ester Topcoat: Curing Agent = 100 : 1.2
• Vinyl Ester Clear Resin: Curing Agent = 100 : 1.2

≥ 30°C

• Vinyl Ester Topcoat: Curing Agent = 100 : 1.0
• Vinyl Ester Clear Resin: Curing Agent = 100 : 1.0

Aggregate & Filler Specifications

• Coarse sand: 20–40 mesh
• Medium sand: 40–70 mesh
• Fine sand: 80–100 mesh
• Quartz powder: ≥ 300 mesh
• Recommended filler: 325-mesh quartz powder or talc powder
