ARALDITE®
420 A/B is a two-component room temperature curing, epoxy adhesive paste of high strength and
toughness.Performances can be enhanced by post-curing at elevated temperature. It is suitable for bonding a wide
variety of metals, ceramics and many other substrates in common use.
Properties :
- Very high lap shear and peel strength .
- Bonds a wide variety of materials (metal, composite and thermoplastics) .
- Good moisture resistance .
- Extremly tough and resilient adhesive .
- Good moisture resistance .
Application of adhesive :
The resin/hardener mix is applied with a spatula, to the pretreated and dry joint surfaces.
A layer of adhesive 0.05 to 0.10 mm thick will normally impart the greatest lap shear strength to the joint.
The joint components should be assembled and clamped as soon as the adhesive has been applied. An even
contact pressure throughout the joint area will ensure optimum cure.
