PRODUCT DESCRIPTION

ERS™ 200 is a two-part epoxy adhesive with exceptional bonding properties, ideal for impregnating high-strength and high-modulus fibers. It exhibits no shrinkage during hardening and offers excellent adhesion to building materials. This adhesive cures rapidly and provides remarkable mechanical and chemical stability. FRP epoxy adhesives are renowned for their superior adhesion, chemical and thermal resistance, mechanical properties, and electrical insulation. They exhibit excellent resistance to base solutions, making them suitable for applications involving tanks with mineral salts.

Application of FRP adhesive in structures and buildings

FRP epoxy adhesives and resins are widely used in construction and civil engineering thanks to their ability to bond large surfaces and heavy joints. They find applications in producing adhesives, plastics, paints, coatings, primers, sealants, flooring, and other construction products. They are commonly employed in constructing multi-layered wooden decks, walls, ceilings, and other items requiring solid connections to the substrate. The versatility of epoxy adhesives allows them to bond to various surfaces such as wood, metal, glass, stone, and certain plastics. They offer superior resistance to heat and chemicals compared to many other adhesives.

Retrofitting of concrete structures using FRP adhesive and resin

FRP composites, composed of a polymer substrate and high-strength continuous fibers like glass and carbon fibers, provide a simple, cost-effective solution for repairing and reinforcing concrete structures. On-site production of FRP composites through the wet lay-up process involves impregnating carbon or glass fibers with epoxy and bonding them to prepared concrete substrates. Once the FRP adhesive has cured, it becomes an integral part of the structure, functioning as an external reinforcement system. The process typically includes using a primer to enhance the adhesive-substrate bond, epoxy putty to fill voids and surface cracks, and saturated resin to impregnate the fabric and adhere it to the concrete substrate. A protective cover safeguards the FRP system from mechanical and environmental damage.

Wet lay up process

The wet lay-up process involves impregnating fibers with FRP epoxy adhesive and applying them manually to a prepared surface. Achieving desired properties requires observing the correct fiber-to-resin ratio. Generally, heavier fibers and reinforcing materials necessitate more significant amounts of resin for proper impregnation. The optimal ratio is typically 60% fiber to 40% resin.

Selecting the appropriate FRP epoxy resin

When choosing an adhesive or FRP fiber resin for your project, consider factors such as the required epoxy layer thickness, curing time, the need for a mold, desired wear resistance, impregnation of reinforcing material, special epoxy properties, and exposure to extreme temperatures, humidity, chemicals, UV light, or other harmful agents.

Priorities for choosing FRP epoxy

Ensure measured strength meets requirements. Consider curing time and hardening properties. Evaluate viscosity. Check waterproofing capabilities.
