Sikadur-330 IN
Two-part thixotropic epoxy impregnation resin for dry-applied SikaWrap fabric strengthening
Product Overview
Sikadur-330 IN is a two-component, thixotropic epoxy impregnation and laminating resin used in the dry application of SikaWrap® structural strengthening fabrics. Applied by trowel and roller, its non-sag consistency performs well on vertical and overhead surfaces, where it both primes the substrate and saturates the fabric to form a high-strength bonded composite. Beyond fabric impregnation, it serves as a structural adhesive for bonding Sika® CarboDur® NSM profiles and SikaWrap® FX anchorage cords. Once cured, it transfers load into the reinforcement to restore or increase the capacity of concrete and masonry elements. The resin mixes easily, bonds strongly to concrete and develops high mechanical properties. Space Arc Engineering, an authorized Sika distributor in India, supplies Sikadur-330 IN in pre-batched site packs.
Features & Benefits
- Thixotropic, non-sag body ideal for vertical and overhead dry-application strengthening
- Acts as both substrate primer and fabric impregnation resin in one product
- Also bonds CarboDur NSM profiles and SikaWrap FX anchorage cords
- Easy trowel and roller application for manual saturation on site
- Strong adhesion to concrete with tensile adhesion around 4 N/mm2 and concrete failure
- High mechanical properties for durable, load-transferring composite reinforcement
Technical Highlights
| Coverage | Consumption is approximately 0.4 to 1.5 kg/m2, depending on substrate roughness and the SikaWrap fabric used. |
| Strength | Tensile strength of approx. 30 N/mm2 and tensile adhesion around 4 N/mm2 with concrete failure. |
| Performance | Flexural modulus of elasticity around 2,800 N/mm2; full cure in 7 days at +30C with a 6-hour minimum before overcoating. |
| Application Conditions | For ambient and substrate temperatures of roughly +10C to +40C; pot life about 35 minutes per 100 g at +30C. |
| Packaging | Supplied as 3 kg pre-batched A+B, or as separate containers (Part A 2.4 kg, Part B 0.6 kg); mixed 4:1 by weight. |
Applications
- Dry-application FRP strengthening of beams and slab soffits
- Column confinement and shear upgrades on building frames
- Bonding CarboDur NSM profiles into concrete for flexural strengthening
- Anchorage of SikaWrap fabrics using FX cords on retrofits
- Seismic and load-upgrade reinforcement of bridges and structures

Frequently Asked Questions
What is Sikadur-330 IN used for?
It is a thixotropic epoxy resin used to prime substrates and impregnate SikaWrap fabrics in dry-application strengthening. It also bonds CarboDur NSM profiles and SikaWrap FX anchorage cords.
What is the coverage of Sikadur-330 IN?
Consumption is approximately 0.4 to 1.5 kg/m2, depending on substrate roughness and the SikaWrap fabric. The project method statement should be followed for precise quantities.
What is the pot life and mix ratio?
Pot life is about 35 minutes per 100 g at +30C, shorter in heat and longer in cooler conditions. The resin is mixed at a 4:1 ratio by weight.
When should I choose Sikadur-330 IN over Sikadur-300 IN?
Sikadur-330 IN is thixotropic and suited to dry application and vertical or overhead surfaces, whereas Sikadur-300 IN is a lower-viscosity resin for wet-layup saturation. Selection follows the strengthening method specified.
