Harmonization Code : 3403.19 | Lubricating Preparations (With 70% or More Petroleum Oils) For Automotive and Other Uses
Main features
- 165% Elongation at Break
- About 50000 cP Viscosity
- 0.05 to 0.10 mm Bondline
Product Description
ARALDITE 2040 A/B is a two-component flexible polyurethane adhesive supplied as a gray paste for bonding plastics and primed metals. The as-supplied adhesive has viscosity about 50000 cP at 25 deg C and density about 1.2 g/cm^3. A 0.05 to 0.10 mm adhesive layer normally gives the greatest lap shear strength in the stated joint guidance. Cured properties after the stated 16-hour cure at 40 deg C include 165% elongation at break under ISO 527, 9 MPa tensile strength under ISO 527 and 4 N/mm roller peel under ISO 4578. Applications include polycarbonate, polyamide and primed-metal bonding.
Key features
- About 50000 cP viscosity: Measured at 25 deg C for the as-supplied adhesive.
- 165% elongation at break: ISO 527 after the stated 16-hour cure at 40 deg C.
- 0.05 to 0.10 mm bondline: This adhesive-layer range normally gives the greatest lap shear strength in the stated joint guidance.
Applications
Bonding polycarbonate, polyamides and primed metals.
