Reduce costs with the vactac hot melt system

| | Leave a Comment

The vactac hot melt system is the cleaner, safer, and more cost-effective alternative to aerosol-based adhesives, used for attaching composites in the vacuum infusion process. Not only does vactac provide more secure bonds in a fraction of the time, but it also does so without generating waste.

How it works

Unlike traditional spray adhesives, vactac adhesives are applied using Power Adhesives’ specially designed applicators. The tec 6300 and 7300 dispense adhesive in a “swirl” pattern using compressed air and a unique nozzle that turns the extruded bead into a thin, spiral filament. The spiral pattern is easily adjustable to create a thinner filament over a wider area.

As the adhesive is applied, it rapidly cools and creates a wider area of coverage than can be achieved by other hot melt applicators. Unlike spray-can adhesives, there is no atomisation of particles, a particular problem when these adhesives contain harmful solvents or VOCs.

Cost saving benefits

Any solvent-based adhesive will have a number on the can or canister showing how much of the contents are solid, usable adhesive. This can be anywhere from 10% to 40% or 50%, depending on the adhesive, with a higher number, signifying more adhesive in the can. Used aerosol cans must also be disposed of, which can incur further costs.

Containing no solvents or VOCs, the vactac system allows customers to use 100% of the adhesive, with no waste product. Any remaining adhesive left in the applicator is simply remelted the next time it’s switched on without impacting its adhesive qualities.

As well as being easy-to-use, vactac adhesives provide a higher instant tack than most other spray equivalents, which also encourages the use of less adhesive. Ensuring an almost instant hold upon composite placement, this also helps to prevent overspray, a common issue when working with adhesives that atomise when sprayed. Overspray can cause an unnecessary mess to working environments and create potential bonding issues, with extra adhesive causing an uneven surface, meaning some areas may not make sufficient contact with the substrate.

As mentioned previously, the unique application method for vactac cools the adhesive far more quickly than is achievable via other applicators. This means vactac adhesives work with heat-sensitive substrates such as foam or expanded polystyrene without causing damage.

What are the three types of bonding failure?

In the adhesives industry, bond failures can’t always be attributed to a single factor. With several different variables involved in why a bond may fail, it is important to understand what each failure is, and what can contribute to the failure occurring. Substrate Failure Substrate failure occurs when the adhesive bond is so strong that […]
