Hexion Holdings Corp. recently announced that, as a result of its ongoing strategic review, it has entered into a definitive agreement to sell its epoxy-based Coatings and Composite businesses.

The Society of Plastic Engineers (SPE) recently recognized Hexion’s composite technology at the society’s Annual Automotive Innovation Awards Program.

Structural adhesives, also known as load-bearing adhesives, are substances that harden and fasten two similar or dissimilar substrate elements with high-modulus, high-strength, and permanent bonds.

You have a wide range of possibilities here. Normally, you would require an adhesive that has been toughened with a rubber for this.

When manufacturers are looking to use adhesives in an assembly operation, three steps must enter into the decision process: suitability, compatibility, and capability.

We are using epoxy adhesives to bond steel substrates that are exposed periodically to both 150˚C and as low as 0˚C. Our problem is in maintaining adhesion to the two steel surfaces at such divergent temperatures because of the response of materials to thermal conditions when going through heating and cooling cycles. Do you have any suggestions?
