Huntsman industrial adhesives

This guide is designed to help engineers overcome the reservations they may sometimes have about adhesives. It includes a survey of modern adhesives and shows how joints should be designed and pretreated in order to make the best use of adhesive bonding.

When components are bonded together, the adhesive first thoroughly wets the surfaces to be bonded together filling the gap in between and then starts to polymerize. When hardening is complete, the bond can withstand the stresses of use. High performance adhesives harden through chemical reaction and have a strong affinity to joint surfaces. Adhesive bonding is sometimes called chemical joining to differentiate it from mechanical joining.

Our industrial adhesives form extremely strong and durable bonds with plastics, metals, glass, rubber and many other materials. Designers in just about every industry increasingly find that bonding with Huntsman adhesives provides the answer to production problems created by new materials, new uses of existing materials, and new techniques and manufacturing methods.

For best results:

1. Resin and hardener components must be measured in the correct ratio and thoroughly mixed together.

2. Joint surfaces must be degreased and, when necessary pretreated.

3. Minimum curing temperature and curing time must be observed (data given in the technical datasheets).

4. Prevent the bond surfaces from moving relative to one another during the curing process.

5. Light pressure should be applied as evenly as possible over the whole bond area. Excessive pressure leaves the joint starved of adhesive.

Designing to bond

In order to get the best performance from an adhesive bond, it is important to design the component for bonding rather than simply taking a design made for mechanical fastening.

Methods of application of the adhesive and the assembly of the components, must always be considered at the design stage. Together, with the practical curing conditions, these determine the choice of adhesive type to be used.

A quality bond can only be produced when quality is considered at all stages of the design and production process.
