Select Curing / Vulcanizing Agents for Adhesives

By Edward M. Petrie

The transformation of a liquid resin to a solid adhesive or sealant is achieved by the addition of chemically active compounds known as curing, cross-linking, or vulcanizing agents. They are substances that are added to a polymeric resin to assist the curing reaction and cross-linking to further increase the thermal stability and mechanical properties of the polymer. But how cross-linking affects the mechanical strength of a sealant? What are there important factors that need to be considered for selecting the right curing additive for adhesives? Explore the chemistry behind cross-linking in detail and learn the criterion of selecting the right curing...

Selection and Formulation of Common Fillers and Extenders

By Edward M. Petrie

Fillers and extenders are added to adhesive formulations in order to reduce cost, improve processing and performance properties. The use of fillers and extenders can also impair certain properties, hence the formulator must balance the expected improvements against possible property decline. Fillers and extenders generally have different functions which may overlap and then they can be thought of as serving the same purpose depending on the application. Make your selection process easy by getting in-depth knowledge about filler and extenders, their effects, applications, and formulation examples.

UV/Light Stabilizers for Adhesives
When adhesives and sealants are used in outdoor environments, the action of light can lead to detrimental effects on both appearance and performance. UV degradation usually manifests itself by either or both discoloration and a reduction in joint strength and general physical properties. The effect of UV radiation on a joint is not only due to changes in the adhesive or sealant, but changes in the substrate could also occur due to UV exposure. Although UV resistance is often a minor concern in the selection or formulation of an adhesive or sealant, it can be extremely important in certain systems and...

Selecting Conductive Fillers for Adhesives & Sealants

By Edward M. Petrie

Conductive fillers are widely used to promote the electrical and thermal conductivity in adhesives and sealants. Selection of the proper filler and its loading level can have a profound effect on conductivity, cost, formulating characteristics, and final mechanical properties. While, for a specific filler there can be several variances, such as size (mean and distribution), aspect ratio, surface area, and surface chemistry, how can you ensure you have the right material for the success of your product. Whether you are creating a new product or optimizing the existing one, learn everything you need to know about conductive fillers here. Electrical Conductivity...

Polymers and Additives for Pressure Sensitive Adhesives

By Edward M. Petrie

Pressure sensitive adhesives, when in the dry state, are aggressively tacky at room temperature and possess a high degree of "quick stick" or initial grab. They can adhere to a variety of dissimilar materials without the need for much more than slight pressure. Often the pressure is applied by hand, but rollers, presses, and other mechanical devices can also be used. There’s always a scope for tailored performance for a particular high-end application. But, how to select the right additive for your requirement? Learn here, the additives and polymers that are used in pressure sensitive adhesives and how overall performance properties...

Test Methods to Measure Impact Strength of Adhesive Joints

By Edward M. Petrie

Adhesives react differently at high loading rates than they do under more normal static loading conditions. Hence, the study of the behavior of adhesive joints under impact loading is now a very active field of research, driven by significant industrial interest. Many industries, such as the automotive & aerospace, are employing adhesive joints with high impact strength. These structural bonds are not only important to obtain application-specific mechanical performance, but they also provide adequate safety levels for their occupants during collisions. Therefore, understanding the behavior of adhesive joints under impact is crucial for designing stronger and safer structures. Explore some of...
