Adhesives for industrial applications

Start with both substrates, their surface condition, the bond area and the load on the joint. Add the temperature, moisture, exposure to other media and the conditions in production. Application method, possible fixturing and the point at which the assembly must be processed further also matter. These details turn a general adhesive enquiry into an application that can be assessed. Krückemeyer GmbH can use them to narrow down suitable systems; the specific product and joint still need to be checked against product data and actual service conditions.

The number of components describes whether a product is applied as one system or whether separate resin and hardener must be combined. The curing mechanism describes what causes the adhesive layer to solidify. For example, a one-component anaerobic adhesive cures in the absence of oxygen and in the presence of metal. Mixing and a limited working time matter for a two-component system. Neither designation alone identifies the adhesive chemistry or proves suitability for a substrate. Consult the technical data and processing instructions for the specific product.

They refer to different stages of bonding. Depending on the system, open time limits the interval between application and joining; mixed systems may also have a separate working time. Fixturing keeps the parts in position while the joint is not yet sufficiently strong. Product-specific curing determines when the intended properties are reached. Temperature and part thickness can affect this process. Plan application, joining, fixturing and later loading separately using the data for the selected adhesive.

If the main task is sealing a joint or potting a component, start with the corresponding category. Sealing or potting is a different selection task from transferring load between two bonded parts. The required function, geometry, movement, environment and application method all matter. Some products can combine functions, but the suitability of a particular product must follow from its data. Describe the intended result first, then assess the system designed for that task.

Check these requirements for the individual product under the intended service conditions. A category name alone does not establish approval for every temperature, prolonged water exposure or food contact. Specify the substrate, medium, duration of exposure and load on the joint. Keep application temperature separate from temperature during later use. Krückemeyer GmbH can use product data for an initial selection; missing approvals and limits of suitability must be clarified before use.
