Flame retardant elastic adhesive

Written by: Chris Shaw | Published:

Global adhesive manufacturers ThreeBond has launched a flame retardant version of its TB1530 series 1-component moisture curing elastic adhesives.

The TB1537 is certified to UL94 V-0 and is both phosphorous and halogen free. According to ThreeBond, this makes it suitable for electronics/electrical applications such as bonding of inverters/converters onto substrate, motor coils, sensor potting and sealing of battery packs for laptops.
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 adhesion to a variety of substrates.
TB1537 has been designed for use with 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. TB1537 is available in white, black or grey.
