EPOXY RESIN SYSTEMS
SUNEPOXY 358: Two-component, high-viscosity epoxy resin
- Corrosion protection of steel, reinforcement steel, and repair mortar
- Bond coat for old and new concrete
- Hygienic and chemical resistant
- Joints of metals, flooring screeds
- Chemical-resistant linings etc
- Tough abrasion, chemical-resistant film
- Excellent adhesion to many surfaces, including concrete or metal substrates
- Formulated specially to provide high chemical resistance
- Free the surface from loose material, grease, and oil by grit blasting or water jet
- Dry the surface completely
- SUNEPOXY 358 has a 2:1 resin: hardener volume-based ratio
- Mix the materials thoroughly
- Apply the first coat of mix by brush as the priming coat
- While the priming coat is wet and tacky, place the epoxy mortar in the required thickness
- Level with a trowel
- Prepare a seal coat & apply this mix with a soft paintbrush over the mortar layer
SUNEPOXY 368: Two-component, low-viscosity epoxy resin [injection grout material]
- Used as a repair material in small gaps, cracks, honeycombs, etc., where no other material can reach
- The use of cement grout may not be efficient due to high shrinkage, low bond, and tensile strength
- Hence, very low-viscosity epoxy injection grout often solves the problem and provides structural integrity
- High bond strength, good tensile strength, low viscosity, and early curing
- SUNEPOXY 368 has a 3:1 resin: hardener volume-based ratio
- Remove loose, disintegrated, and porous concrete at cracks and joints
- Drill injection holes to a depth of 2-4 inches in the concrete
- The drilling of holes depends on 3 factors
- The 3 factors are the width of the cracks, the extent of damage, and the dimensions of the structural elements
- Inject the mixture of epoxy resin and hardener at a pressure of 50-100 psi
SUNEPOXY 378: Two-component, medium viscosity epoxy resin
- Repairing old & new concrete surfaces in the following areas –
- warehouses
- manufacturing plants
- hospitals
- chemical plants
- Used as a gap-filling adhesive, bedding bridge beams
- Steel bridge bearings, securing bolts into walls, etc
- Conforms to ASTM C 881-99, type 1, grade 3, Class B & C
- Low odour during application
- Provides non-absorbent, non-dusting, chemical-resistant surface
- Bonds tenaciously to become an integral part of the floor
- High tensile and high compressive strength
- Thixotropic, so non-sagging
- Clean all surfaces dry and make them free of any oily residue which will interfere with proper adhesion
- All cracks over 2 mm wide should be routed out to a 6 mm width and 6 mm depth before application
- Fill routed-out cracks and cut joints with SUNEPOXY 378 (MORTAR)
- Apply the material over the rest of the surface
- For patching, spread with a trowel to the required level
- Use a thin coat of solvent on the trowel to aid workability
FAQs
Why do people use epoxy resin?
People use epoxy resin for its excellent adhesive qualities, which are stronger than most other types of glue. Its ability to bond with a variety of materials, including metal, wood, glass, and plastic, makes it invaluable for both industrial applications and DIY projects.
What is epoxy best used for?
Epoxy is best used for applications requiring strong adhesion, durability, and resistance to chemicals and wear. It excels in creating high-strength bonds in construction, automotive repairs, and manufacturing. Epoxy coatings are ideal for protecting and sealing floors in industrial and commercial settings.
What is epoxy used for in construction?
In construction, epoxy is primarily used as a high-strength adhesive for bonding building materials like concrete, wood, and metals. It’s also applied as a durable, protective coating for floors, especially in industrial and commercial buildings, and used for repairing cracks and strengthening weakened structures.
What is general-purpose epoxy resin?
General-purpose epoxy resin is a versatile, two-component system comprising a resin and a hardener. It’s designed for a wide range of applications, including adhesive bonding, coating surfaces, and filling gaps. This resin is known for its strong adhesion, durability, and resistance to chemicals and moisture, making it suitable for both industrial and household uses.
Is epoxy better than cement?
Epoxy is better than cement in specific applications that require high strength, excellent adhesion, and resistance to chemicals and moisture, such as in repairing cracks, bonding different materials, and protective coatings. However, for large-scale structural construction like building foundations, walls, and laying floors, cement is more practical and cost-effective.
