Styrene-free vinyl ester chemical mortar 345 ml. Quantity per package: 12 pieces. 345VSF

Versatile heavy-duty chemical anchor

ResiFIX VY SF is a vinyl ester injection mortar distinguished by its styrene-free formulation, making it a safe choice for work in enclosed spaces. With an A+ emission class, the product meets rigorous indoor air quality standards, emitting no harmful substances during application. This is a key feature for installers working in ventilated areas or during renovations, where the health of the crew and end users is a priority. This mortar not only protects the work environment but also ensures high connection strength under challenging conditions.

Application in cracked concrete and wet holes

A unique feature of this system is the ability to install in water-filled holes and cracked concrete—situations that often preclude the use of standard mechanical anchors or other resin types. Thanks to this, ResiFIX is ideally suited for foundations, basement walls, and structures exposed to moisture. The product holds official ETA approval and a CNBOP certificate, confirming its suitability for very high loads.

In practice, this means it can safely secure:

• heavy steel structures and industrial machinery;
• protective railings and balustrades;
• cantilevered brackets and canopies;
• façade elements and wooden substructures;
• reinforcement bars and mounting bolts in solid brick and concrete.

Installation occurs without generating expansion stresses around the hole, which is particularly important for thin walls or brittle materials. An additional advantage is fire resistance rated at R120, allowing the mortar to be used in zones requiring a high fire-resistance class for load-bearing structures.

Installation efficiency and operational parameters

For professionals, strength is not the only factor; speed and ease of work are equally important. The 345 ml cartridge mortar (supplied in bulk packs of 12 units) enables precise mixture dosing thanks to dedicated mixing nozzles. The absence of styrene also results in a milder odor during application, improving work comfort without the need for additional respiratory protection (while adhering to standard HSE guidelines).

The ResiFIX VY SF system eliminates the risk of material cracking around the anchor due to its specific binding chemistry, which does not require expansion like mechanical anchors. This solution is effective for both small home renovations (e.g., mounting shelves) and large industrial projects requiring certified anchoring of heavy machinery or industrial gates. Thanks to the ability to install in wet holes and cracked concrete, installers gain confidence in achieving effective adhesion even under the most unfavorable moisture or structural foundation conditions.
