Epoxy Waterproofing Resin In Andhra Pradesh
Details of Epoxy Waterproofing Resin
Epoxy waterproofing resin is a durable and versatile material used primarily for protecting surfaces from water ingress, chemical exposure, and mechanical damage. It’s commonly applied in construction, marine, industrial, and flooring applications due to its excellent adhesive and sealing properties.
What is Epoxy Waterproofing Resin?
Epoxy waterproofing resin is a two-component system consisting of:
Epoxy resin (Part A)
Hardener (Part B)
When mixed, they undergo a chemical reaction (polymerization), forming a rigid, highly adhesive, and waterproof thermoset plastic.
Key Features
Excellent waterproofing: Forms a seamless, impermeable barrier.
Strong adhesion: Bo tcnds to concrete, metal, wood, tiles, and more.
Chemical resistance: Resists oils, acids, solvents, and saltwater.
Mechanical durability: Withstands heavy traffic and impacts.
Long lifespan: Once cured, it offers long-term protection.
Low shrinkage: Minimizes cracking during curing.
Common Applications
Basement and foundation waterproofing
Water tanks, swimming pools, and reservoirs
Roof decks and terraces
Industrial floors (as part of epoxy flooring systems)
Marine environments (boats, docks, etc.)
Bridges and tunnels
Types of Epoxy Waterproofing Resin
Solvent-free epoxy: Environmentally friendly, thicker application.
Solvent-based epoxy: Thinner, good for penetrating porous substrates.
Water-based epoxy: Easier cleanup, lower VOCs, but less durable.
Application Process
Surface Preparation: Clean, dry, and free of dust, oil, or loose material.
Primer (optional): Applied to enhance adhesion.
Mixing: Combine resin and hardener in the correct ratio.
Application: Use brush, roller, or squeegee; may require multiple coats.
Curing Time: Typically 8–24 hours, depending on product and temperature.
Technical Properties (Typical)
Property Value (Approximate)
Mixing Ratio (A:B) 2:1 or 1:1 (by volume or weight)
Pot Life 20–45 minutes
Curing Time 12–24 hours (initial), 7 days (full)
Shore D Hardness 75–85
Water Absorption <0.2%
Coverage ~1.5–2 m²/kg (per coat)
Limitations
UV sensitivity: Can yellow or degrade under prolonged sunlight; use a UV-resistant topcoat if exposed.
Temperature-sensitive: Should be applied above 10°C (50°F).
Surface must be dry: Cannot adhere well to wet or damp surfaces unless using moisture-tolerant formulations.
