Product Overview

SikaWrap-430 G is a unidirectional woven E-glass fibre fabric used as externally bonded reinforcement in the Sika strengthening system. The 0-degree white glass filaments carry tensile load, while a thermoplastic heat-set weft holds the sheet stable for handling. Saturated on site with Sikadur epoxy by wet or dry lay-up, it forms a tough glass laminate bonded to concrete, masonry, brickwork or timber. Because glass is electrically non-conductive and lower in modulus than carbon, the fabric is preferred where electromagnetic transparency, blast mitigation or higher strain capacity matters, as well as for general seismic and refurbishment strengthening. It is a cost-effective entry into FRP upgrades. Space Arc Engineering, an authorized Sika distributor in India, supplies SikaWrap-430 G with the matching Sikadur resins for strengthening contractors nationwide.

Features & Benefits

• Electrically non-conductive E-glass suits substations, hospitals and EMI-sensitive areas
• Higher strain to failure (about 2.7%) gives ductile, energy-absorbing reinforcement for blast and seismic use
• Installs by both wet lay-up (Sikadur-300) and dry lay-up (Sikadur-330) methods
• Cost-effective glass alternative to carbon for moderate strengthening needs
• Drapes readily over columns, walls and curved surfaces of varied geometry
• Corrosion-free and low weight, avoiding the cover-loss issues of steel plating

Technical Highlights

Applications

• Strengthening structures near electrical substations and transmission equipment where conductivity must be avoided
• Blast mitigation and impact upgrades on infrastructure and defence facilities
• Seismic strengthening and confinement of masonry and concrete buildings
• Refurbishment of corrosion-affected industrial and marine structures
• Strengthening residential and commercial walls, slabs and columns on a budget
