Chemical Anchor Celo 300VSF Resifix vinylester grout (styrene-free) for heavy-duty fastening

Celo 300VSF Resifix vinylester grout (styrene-free) is a two-component chemical anchor designed for bonded anchors and heavy-duty fastenings in concrete and masonry. The styrene-free vinylester formulation provides a corrosion-resistant adhesive bond for threaded rods and rebar, enabling secure load transfer in repair work, structural fixes, and mechanical installations where high load capacity and long-term durability are required.

Advantages

The vinylester resin system cures to form a high-strength bond that resists chemical attack and moisture, while the styrene-free composition reduces volatile organic emissions during application. The two-component cartridge format ensures consistent mixing and reliable performance for through-hole and blind-hole anchoring. Designed for use with steel reinforcing elements and anchors, the grout provides predictable mechanical properties and improved long-term stability in concrete and masonry substrates.

Suitable for

• Fixing threaded rods and stud anchors in new and existing concrete
• Securing rebar dowels for structural repair and strengthening
• Mechanical installations such as base plates, rails, and heavy fixtures
• Anchoring in cracked and uncracked concrete and in masonry applications

Key specifications

• Two-component vinylester resin system (styrene-free)
• Suitable for bonded anchors and rebar dowelling
• Cures to provide high shear and tensile bond strength
• Corrosion-resistant adhesive properties
• Applicable in through-hole and blind-hole installations
• Compatible with concrete and common masonry substrates

How to use

Drill the hole to the specified diameter and depth and clean thoroughly using compressed air or brush alternately to remove drilling dust and debris. Prepare the cartridge according to the manufacturer's instructions and dispense until a uniform colour is achieved to ensure proper mixing of resin and hardener. Inject the mixed grout from the back of the hole to avoid air entrapment and insert the threaded rod or rebar with a slow twisting motion to distribute the grout evenly. Allow the resin to reach full cure before applying service loads, following the temperature-dependent cure times provided by the manufacturer.

Usage recommendations

For optimal performance, use appropriate drill bits and brushes to achieve a clean contact surface, observe substrate temperature limits during application, and follow specified embedment depths and edge distances. When anchoring in cracked concrete or when higher corrosion resistance is required, select suitable stainless or galvanized reinforcing elements and consult relevant design tables for load values and safety factors.
