KRYLEX® KB544 Instant Adhesive is a very high viscosity ethyl cyanoacrylate based adhesive, formulated as a thixotropic gel.
KB544 is specially formulated to give superior bonds on common substrates. KB544 will work on acidic nd porous substrates where other cyanoacrylates fail to bon.
KB544 relies less on surface moisture for cure speed than standard cyanoacrylates.
Typical Applications
KRYLEX® KB544 is speciallyhigh strength, general purpose bonding of most metals, wood, card, plastics, rubbers, leather, fabrics and other common substrates. The gel formulation is suitable for bonding poorly mating components and for porous substrates such as china and other ceramics. It is also suitable for use on vertical and over-head surfaces as it will not drip or slump.
