THREEBOND GO GOLD AGAIN WITH ULTRA HIGH PEEL

Product News Monday, June 22, 2009: ThreeBond Europe S.A.S. (UK Branch)

The ThreeBond 7700 Gold Label series of premium cyanoacrylate instant adhesives has recently been joined by the TB7737 and TB7738 offering ultra high peel and impact resistance by virtue of their added elastomer toughening. This strength enables the TB7737 and TB7738 to be used in areas where conventional “instants” would not survive, e.g. hotter/harsher environments. In addition, the Gold Label series is enhanced by the introduction of a new high-reliability multi-primer for instant adhesives – ThreeBond 7797 is especially valuable on difficult to bond plastics such as nylon, PBT, PE, PP and PTFE where it can produce orders of magnitude improvements in adhesion creating a performance comparable with recognised “no-problem” adherends such as metals and easy to bond plastics.

ThreeBond Gold Label series 7737 and 7738 are produced as semi-gel’s, with viscosities of 2,000cps and 5,000cps respectively, making them drip free, so can be used on vertical surfaces and for electronic parts, speaker components or vehicle weather strip yet fluid enough to dispense or apply to small parts. They both offer greatly increased lap shear strength (resistance to peel) and much improved impact resistance compared to conventional products, especially under high heat stress and hest cycling. TB7737 and TB7738 are characterised by their differing performances dependant on the adherent substrate so it is important to select the appropriate adhesive for the material involved.

TB7797 primer however can be used with any of the 7700 Gold Label series or TB1700 series and features far improved adhesion for difficult adherends, it is quick drying and has good workability with easy application by brush, cotton swab or other.

ThreeBond believe that these three specialised products successfully address the whole “raison d’être” of instant adhesives – to perform instantly over a very wide range of substrates and in varied conditions.
