Product Overview

Sikadur-300 IN is a two-component epoxy impregnating and laminating resin developed for the wet application of SikaWrap® structural strengthening fabrics. It saturates carbon and glass fabrics by hand or machine using an impregnation roller, and also serves as a substrate primer for the wet-layup process. Once cured it locks the fibres into a high-strength composite that bonds to the structure and transfers load, restoring or increasing the capacity of beams, slabs, columns and walls. The resin mixes easily, offers an extended pot life for comfortable saturation, and develops strong adhesion to concrete. With a glass transition temperature around +72C, it suits typical strengthening service conditions. Space Arc Engineering, an authorized Sika distributor in India, supplies Sikadur-300 IN in pre-batched and separate-component packs.

Features & Benefits

• Formulated for wet-layup saturation of SikaWrap carbon and glass fabrics

• Doubles as a substrate primer for the wet application process
• Easy hand or machine mixing and roller application on site
• Strong adhesion to concrete with tensile adhesion around 4 N/mm2 and concrete failure
• Glass transition temperature around +72C suits common strengthening service conditions
