Description
EstoWrap 300 is a high tensile strength, high elastic modulus sheet of longitudinally oriented continuous carbon fiber elements held in place by a lightweight, open mesh scrim. This FRP material, when used with a specially developed primer, enhances structural performance by strengthening shear strength and deformation properties. It conforms to the ACI 440.2R-17 design standard and passes ASTM D3039 for composite materials.

Instruction to Use
Preparation
The concrete surface must be dry, smooth, sound, and free from debris and loose material. It should also be fully cured and free from contamination. Thoroughly prepare the substrate by lightly grit blasting to remove all deleterious substances and provide a suitable key. Remove all dust and debris before proceeding.
Priming
Stir the base and hardener components of EstoWrap Primer thoroughly. Pour the hardener into a mixing vessel, add the base resin, and use a heavy-duty drill with a mixing paddle. Mix thoroughly, scraping all containers clean. Apply EstoWrap Primer to the prepared substrate with a stiff brush, ensuring good coverage at 0.3 kg/m².
Application
Prepare enough material, manpower, and equipment to finish within the resin's pot life. Mix EstoWrap Resin as per primer instructions, apply with roller at 0.6 kg/m² on primed surface. Apply pre-cut EstoWrap 300 Carbon Fabric Sheet (up to 4m long) with rubber or plastic scraper, roll parallel to carbon fibers. Apply a second coat of EstoWrap Resin at 0.6 kg/m² within 30 minutes to 3 hours to fully encapsulate the fabric.
Other Applications
EstoWrap 300 strengthens structures externally, providing blast mitigation, reinforcing pipes, silos, tanks, steel, slabs, walls, domes, tunnels, and chimneys.
Limitation
EstoWrap 300 should be protected via over coating with a PU based UV resistant coating within 6 hours of application.
