Faster curing with Loctite MAX2
With lightweighting in mind, automotive manufacturers are using more and more parts made from carbon fibre or glass fibre composites. With this in mind Henkel says that it has developed a polyurethane-based composite matrix resin that cures faster than the traditional epoxy resins.
C
omposites based on carbon fibre or glass fibre are gaining momentum in various application areas due to the opportunity for enormous weight savings over traditional part construction, with no loss in mechanical performance. Starting in aerospace where pre-impregnated fibres (prepregs) are manually laid up and then baked into composites, many different applications are now penetrating into the automotive industry. New manufacturing
methods like resin transfer molding enable economic processes that are suited for high volume automotive production. For the resin transfer molding process, Henkel has developed a new composite matrix resin based on polyurethane that
enables improved economics and throughput in processing. Compared to standard epoxy matrix resins, Henkel says the new Loctite MAX2 cures significantly faster. During injection it also enables more efficient impregnation without stressing the fibres due to the lower viscosity of the resin. “The composite properties of Loctite MAX2 were specially developed to provide more flexibility as well as much higher
impact resistance than traditional epoxy resins. We are confident that this new generation of polyurethane matrix resins deliver significant benefits for fast and efficient manufacturing.”
Get the ferry locked up in a hurry
For the marine contractor tasked with fitting out a Bahamas based ferry there was the little problem of a glitch in the supply chain - with a need for a complete fit of special cabinet locks for the personal storage areas – and the locks had to be on-board in two days.
F
ortunately this is exactly the sort of situation that FDB Panel Fittings says it is able to deal with. The company searched its large stock of similar cabinet fittings to find the correct type and quantity of locks, with master key and zone locking facility. Once located it was then a matter of organising transport logistics by air to Miami and onward to the Bahamas in time for the ship’s maiden voyage.
Standing ovation for Quicktight™
Quicktight™ says that it is offering a fastening solution that allows solid fixation of objects while maintaining the flexibility to unfasten these objects in a user-friendly way.
H
aving developed a patented fastening technology Quicktight™ has arrived at the stage to expand this concept further outside of the Netherlands and also into other application areas. The roots of Quicktight™ are in the theatre world where there is the cumbersome task of changing seating arrangements to adapt to different events. The Quicktight™ fastening solution was developed to allow quick
clearance that still guarantees the theatre seats to be secured in a proper way when the chairs are moved back to their former setting. This was the birth of the Quicktight™ concept and product. “Besides chairs there are other applications in the theatre that are being targeted for instance lightning equipment.
To further expand the business case for this fixation concept there is also a strong belief in significant opportunities outside the theatre world. Areas that are being considered for this fastening concept are the transport sector – trucks, vans, cars, as well as aerospace.”
