Araldite 2040 A/B is a two component, low shrinkage, flexible polyurethane adhesive. This advanced material is well suited for bonding polycarbonate, polyamides as well as primed metals. It has excellent gap filling properties and the material is ideal for thick bondlines. The product is specifically designed to be used as a structural adhesive and it is ideal for bonding plastics.
Araldite 2040 component A Resin is white and Component B Hardener is black, once the two components are mixed together it creates a black paste. Specific gravity at 77° F is 50,000 ca. and the pot life of 100 gm at the same temperature will be approximately 15 minutes. When applying the adhesive, it is important to properly clean and treat the surfaces to be bonded. Mix ratio is 92 parts by weight of component A and 100 parts by weight of component B. This adhesive is available in cartridges incorporating mixers and it can be applied as ready to use adhesive.
When applying to the joints that need bonding, Huntsman recommends a layer of 0.002 to 0.004 in thick. The thickness recommended will normally impart the greatest lap sheer strength to the joints. Araldite 2040 Adhesive cure time will be dependent on the temperature. At 50° F, cure time will take approximately 17 hours for Lap Shear Strength to be greater than 145 psi. Speed cure at 212° F will take 25 minutes to achieve a Lap Shear Strength greater than 1160 psi. Tested for tropical weathering at 73° F LSS after 30 days is 470 psi. After 90 days with tropical weathering, the material is completely degraded.
