Vactac

Solvent-Free Adhesive System for Vacuum Infusion Composites

Vactac® is an environmentally responsible, high-performance hot-melt adhesive system developed as a direct alternative to solvent-based spray adhesives. Designed for composite manufacturing with vacuum or resin infusion, it replaces traditional aerosol cans with a safer and more economical solution.

Key Benefits

Source: poweradhesives.com/vactac

VOC-Free, No Organic Solvents

It avoids the organic solvents and hazardous substances found in traditional spray adhesives. Hot-melt cartridges applied with compressed air are safe, clean and easy to store.

100% Solids Content

Many spray cans contain only 15-20% adhesive and the rest is volatile solvent. Vactac® is 100% solids, so everything applied is adhesive.

No Airborne Particles

Unlike atomised spray systems, Vactac® does not generate airborne particles, reducing the need for respirators or air filtration.

Technical Advantages

The Vactac system combines high performance with environmental and occupational safety advantages.

High Instant Tack

Speeds production without clamps or long waiting times while providing excellent bond strength and durability.

Does Not Block Resin Flow

Supports uninterrupted resin flow during lamination, helping improve production quality and efficiency.

Maintains Structural Integrity

At a coating weight of 10 g/m², ILSS reduction remains below 8%, so strength loss is negligible compared with reference laminates.

Repositionable

Glass fibre layers can be repositioned easily without sacrificing tack, supporting precise alignment.

Cost-Effective Solution

Vactac® combines cost savings, environmental benefits and high performance for long-term adhesive efficiency.

Application Areas

For more than 20 years, Vactac® has been used successfully as a positioning adhesive before lay-up in different composite manufacturing fields.

Wind Energy - Turbine Blades

Used for more than 20 years as a positioning adhesive before lamination in wind turbine blade production.

Marine - Boat Hull Production

Suitable for applications from inflatable boats to superyachts, including specific resin pipe tacking formulations.

Transport and Aerospace

Used in commercial vehicle bodies, interior storage units and aircraft exterior panel production.
