Applications

Epoxite General Purpose Epoxy System is designed to offer dependable, all-around performance across industrial, construction, and maintenance sectors. Its balanced formulation of high strength, flexibility, and chemical resistance makes it suitable for a wide range of everyday applications, including:

🏗  Civil Construction & Repairs
Ideal for concrete crack repairs, bonding of structural elements, tile grouting, and anchoring bolts.

🔧 Industrial Maintenance
Used for coating and sealing steel surfaces, pipelines, tanks, and machinery parts exposed to moisture, chemicals, or corrosion.

⚡ Electrical Encapsulation
Suitable for potting and encapsulating low-voltage electrical components, ensuring insulation and environmental protection.

🧱 Adhesive Applications
Works as a high-strength adhesive for bonding metals, ceramics, composites, and concrete.

🖌  Protective Primers & Coatings
Can be applied as a base coat on substrates requiring corrosion and chemical resistance in marine, infrastructure, and industrial environments.

🛠  Tooling and Casting (with filler)
When mixed with suitable fillers, it is excellent for creating jigs, moulds, and general-purpose castings with minimal shrinkage.

Processing & Application Guidelines 

• Mix Ratio (by weight)
  100 parts EPG 180 (resin) : 50 parts EH 406 (hardener)

• Mixing Procedure
  1. Stir each component separately before use
  2. Pour the required amounts of resin and hardener into a clean container
  3. Mix thoroughly using a flat spatula or mechanical stirrer at slow speed
  4. Scrape the sides and bottom to ensure uniformity
  5. Avoid introducing air bubbles during mixing

• Pot Life (100 g mix at 25°C)
  Approx. 120–130 minutes (Use within this window for best results)

• Application Method
  - Apply using a brush, roller, trowel, or injection equipment depending on use-case
  - Suitable for casting, bonding, priming, and sealing on concrete, metal, composites, wood

• Recommended Thickness
  - For coatings: 0.3 – 1.0 mm per layer
  - For casting or filling: Apply in stages if depth exceeds 10 mm to avoid excess exotherm

• Curing Schedule
  - Touch-dry: 8–10 hours at 25°C
  - Full cure: 24–36 hours at 25°C
  - Optional post-cure: 40°C for 4 hours to enhance chemical resistance

• Clean-up
  Clean tools and mixing containers with solvent (e.g., isopropyl alcohol or epoxy thinner) before the system cures

Storage & Shelf Life

• Resin (EPG 180): Store between 20°C and 40°C, shelf life of 2 years

• Hardener (EH 406): Store between 18°C and 25°C, shelf life of 1 year

• Protect both from moisture and direct sunlight. Refer to SDS for handling precautions.

Safety

Use PPE when handling. Avoid contact with skin and eyes. In case of contact, wash with soap and water. Avoid inhalation of vapours. Refer to SDS for full safety guidelines.
