ThreeBond Flame Resistant Adhesive
Global adhesive manufacturer ThreeBond has announced a flame retardant version of their established TB1530 series 1-component moisture curing elastic adhesives. The TB1537 is certified to UL94 V-0 and is both phosphorous and halogen free. This makes it especially of interest in electronics/electrical applications such as bonding of inverters/converters onto substrate, motor coils, sensor potting, sealing of battery packs for laptops etc.
The main composition of the TB1537 is a silyl-radical-based special polymer which cures rapidly with moisture in the air to achieve a fast skinning time and very low shrinkage. The cured adhesive is a tough elastomer providing good adhesion to many substrates. In addition TB1537 can be used for applications such as sealing/potting where RTV silicones may otherwise be used. Since TB1537 does not contain low-molecular cyclic siloxanes it does not cause electrical contact failure.
