The solvent-free technology for vacuum infused composites

sustainable & safe

Sustainable, cost-effective and safe-to-use positioning adhesive

The Vactac® adhesive system is the direct replacement for solvent-based spray adhesives, offering users a more cost-effective and environmentally conscious alternative.

VOC-Free Adhesives

Vactac hot melt adhesives are free from organic solvents and other hazardous substances present in spray-can adhesives. Dispensed using compressed air, the hot melt slugs are safe to handle, better for the environment and don’t require any special storage conditions when not in use.

100% Solids

Did you know that spray-can adhesives have only 15 to 20% adhesives in them? Up to 85% of spray can adhesives are solvents that flash off after they’ve been sprayed. Vactac adhesives, however, are 100% solid content, all of which is dispensed in the spraying process.

No Airbourne Particles

Other adhesive systems produce some form of atomised particles that are potentially hazardous to both users and the environment. Vactac hot melts are free from atomized particles, negating the need for any respiratory PPE or air-filtration equipment in factories, reducing running costs whilst keeping workers safe.

Superior Performance

Vactac adhesive delivers superior performance, offering cost savings, environmental benefits, and high efficiency

High Instant Tack

Streamlined Production Processes
Our hot melt adhesive provides superior instant tack, eliminating clamping and curing time. Vactac streamlines manufacturing, ensuring exceptional bond strength and durability without the use of solvent-based spray can adhesives.

Uninterrupted Resin Flow

Ensures Continuous Resin Flow
Vactac adhesives are engineered to seamlessly integrate into the lay-up process, guaranteeing uninterrupted resin flow during infusion. This feature enhances manufacturing efficiency and ensures consistent quality in composite fabrication.

Structural Integrity Preservation

Maintains Laminate Structural Integrity
Vactac adhesives maintain laminate structural integrity with minimal impact on strength or stability. ILSS drop-off, based on a 10GSM coat weight, is less than 8%, demonstrating negligible reduction in strength compared to control laminates.

Repositionability

Flexible Repositioning Capability
Vactac adhesives offer repositionability without sacrificing tack, improving workflow flexibility and precision in composite manufacturing for accurate positioning and alignment of glass fiber layers.

Cost-Effective Solution

Driving Affordability and Sustainability
Vactac offers cost savings, environmental benefits, and high performance. Ideal for businesses balancing budget constraints with sustainability goals, it delivers a compelling solution for long-term success and efficiency in adhesive applications across industries.

    Industry Usage

    Since the early 2000s, the Vactac adhesive system has been changing the way industries approach the lay-up process prior to resin infusion. We prioritise collaboration with our customers to ensure complete satisfaction.

    Wind Energy

    Turbine Blades

    For over 20 years Vactac adhesives have been used in the lay-up process when manufacturing wind turbine blades. Their aggressive tack ensures an instant hold, without interfering in the resin infusion process.

    Marine

    Hull manufacture

    From rigid inflatable power boats to super yachts, vactac adhesives are the ideal positioning adhesives when infusing boat hulls, with special formulations for resin pip tacking.

    Transportation

    Commercial

    Used in all aspects of commercial vehicle construction, our adhesives have been used in the creation of exterior bodywork and internal storage compartments on aircraft.
