Description

Product Introduction

E337 Epoxy Middle Coating is a two-component, solvent-based, low-odor epoxy resin intermediate coating designed for base leveling and surface preparation. It contains filler materials, allowing it to be tinted to match the color of the topcoat. With its low cost, excellent adhesion, high strength, and durability, E337 is ideal for leveling applications in industrial plants, warehouses, underground parking lots, and office spaces.

Key Features

• Color Matching: Can be adjusted to match the topcoat color, reducing the risk of blooming.
• Easy Application: Suitable for scraping with added sand or powder, offering excellent workability.
• Low Odor: Lower odor compared to other solvent-based epoxy products.
• Durable & Strong: Provides high bonding and compressive strength for long-lasting performance.

Technical Specifications

• Drying Time: 2-24 hours (at 23℃, 50% relative humidity).
• Sandability: Easy to sand, non-stick to sandpaper.
• Bonding Strength: >2.5MPa.
• Compressive Strength: >50MPa.

Product Information

• Components:
  • Component A: Solid color viscous liquid, 20kg/barrel.
  • Component B: Curing agent, 5kg/barrel.

• Packaging: Printed metal drums. Recommended stacking up to three layers.
• Storage: Store at 5-35℃ in a cool, dry, and ventilated area. Keep away from fire and heat sources. Avoid direct sunlight.

Application Guidelines

• Surface Preparation:
  • Ensure the concrete floor is dry, clean, and free from dust, grease, or contaminants.
  • Use a floor grinder to remove floating dust and protruding residues.
• Coverage: Approximately 0.4kg/square meter per 1mm thickness (when used with sand).
• Application Method: Apply by scraping using a trowel.
• Pot Life:
  • 90 minutes at 10℃.
  • 60 minutes at 20℃.
  • 30 minutes at 30℃.
• Curing Time:
  • 48 hours at 5-15℃.
  • 36 hours at 15-20℃.
  • 24 hours at 20-30℃.

Recommended Floor System

• 1mm Thin Coating Epoxy Floor System:
  • Primer: 1-2 coats of E159X epoxy primer (0.15-0.2kg/㎡).
  • Intermediate Coat: 1-2 coats of E337 epoxy intermediate paint with sand (0.4kg/㎡ per 1mm thickness).
  • Topcoat: 1 coat of E860 epoxy topcoat (0.06-0.08kg/㎡) or 2 coats of E556 epoxy topcoat (0.22-0.27kg/㎡).

Safety & First Aid

• Skin Contact: Wash with plenty of water and remove contaminated clothing.
• Eye Contact: Rinse with running water or saline. Seek medical attention if necessary.
• Inhalation: Move to fresh air. Keep the airway open. Seek medical attention if unwell.
• Ingestion: Rinse mouth, induce vomiting, and seek medical attention.

Precautions

• Color Matching: The color is similar to the topcoat but not identical.
• Drying Time: Allow 12-24 hours of drying before the next construction step.
• Mixing Ratio: Strictly follow the 4:1 ratio (A:B ) and use within the pot life.
• Storage: Stir well before use if precipitation occurs. Avoid using as a repair material due to solvent content.
