Power Adhesives VAC-TAC adhesive system for vacuum infusion processes provides higher instant tack than aerosols
Article Type: New materials and equipment From: Pigment & Resin Technology, Volume 37, Issue 4
Power Adhesives introduces the VAC-TAC adhesive system for a faster, safer, solvent-free adhesive system for composite companies utilizing vacuum infusion technology.
Compared to traditional aerosol adhesive systems commonly used in the vacuum infusion process, the VAC-TAC system is more economical and helps composite companies lower VOC output. The system is ideal for securing and positioning reinforcement materials and is said to overcome traditional problems usually associated with aerosol adhesive systems. The VAC-TAC system allows building the composite structures faster than alternative methods to save time and reduce production costs. Since the system is solvent-free, health and safety issues are also eliminated.
Strong and durable, the VAC-TAC system holds even large composite material structures in place as well as typical vacuum processing products including reinforced fabrics, foam, balsa, bleeders, breathers, peel plies and release films.
The VAC-TEC system consists of Powder Adhesives TEC 6300 spray hot melt glue gun, 20 ft (6 m) of hose and the VAC-TAC adhesive in a hot melt cartridge form.
To use the VAC-TAC system, connect the glue-gun to an air and electrical supply. The adhesive melts inside the glue-gun chamber and once melted can be sprayed directly onto one of the substrates. The hot melt glue-gun is fully adjustable to a variety of spray patterns and coating widths for optimum flexibility.
Once the reinforcement materials are positioned, resin and vacuum feed pipes can be positioned using the same adhesive system, speeding up this part of the infusion laying process.
Benefits of the system include reduced production costs, solvent-free application for health and safety, higher instant tact than aerosols, easy storage, no shelf-life and no waste and packaging disposal fees.
“The VAC-TACSystem is easy to apply and allows for composite structures to be built quickly saving time and reducing production costs,” explained Lee Stegall, Director of Sales for Power Adhesives. “Not only does the VAC-TACSystem offer economical benefits over other aerosol systems, but by eliminating solvent based adhesives, the composite company improves their employees working environment.”
