Araldite® 2014-2 is a two-component, room temperature curing, thixotropic epoxy paste adhesive. It offers high mechanical strength, excellent resistance to water, chemicals, and elevated temperatures, and is non-sagging with gap-filling capability up to 5 mm. It is widely used in environments where high durability and resistance to harsh conditions are required.
Bonding of metals (aluminium, steel, stainless steel, copper, brass, galvanised steel).
Bonding of composites such as GRP, CFRP, SMC.
Suitable for plastics (ABS, PVC, PMMA, polycarbonate, polyamides).
Used in electronics, structural assemblies, and GRP structures exposed to high temperature or aggressive environments.
