Overview As discussed in our previous article, cationic and free-radical are the two most popular mechanisms for UV adhesives. Approximately 93% of the UV market is in free radical chemistry while cationic has about 7%. Although a minority of the market, cationics provide strategic advantages over traditional free-radical acrylate chemistries. These advantages include: Shadow Cure […]

Often referred to as UV Curing, Ultraviolet Curing utilizes high-intensity ultraviolet light to generate a photochemical reaction which instantly polymerizes adhesives, inks and coatings. The main two types of photochemical reactions used are acrylate free radical and cationic epoxy. UV curing differentiates itself from other traditional drying methods due to its increased production speed, reduced […]
Unlike thermoplastic alternatives such as hot melt adhesives, cured thermosetting epoxies will not re-flow or melt when heated. Instead, epoxies will undergo a transition from a hard rigid state to a more pliable, rubbery state. The temperature range during which this transition takes place is known as the glass transition temperature, Tg.
Epoxies have excellent physical and chemical properties for most electronics applications. These include high strength, good adhesion to a variety of surfaces, and chemical resistance. Neat (unfilled) epoxies are also highly electrically and thermally insulating. Depending on the application, electrical insulation may be required in order to prevent shortages.
In part 3 of our blog series, Resin Designs explored the various types of gel seal connectors. This week, we’ll be discussing connector design considerations. Connector Design Considerations At Resin Designs, we help customers create new connectors with low wire insertion forces using silicone gel grommet seals. Along with this, existing connectors can be modified […]
Historically, lead solders have been the conductive bonding materials of choice, mainly due to the reliable performance and availability of the base materials. However, as the electronics industry strives to create more environmentally and worker friendly electronic products, lead-free solders have been developed and ECAs have gained greater acceptance as a solder alternatives.
The design of gaskets comes in a nearly unlimited number of component arrangements and material combinations from which they inherit their properties. As a result, gaskets can be classified in various ways ranging from the category of the utilized materials to the function and application of the resulting gaskets. Gaskets can also be classified according to […]
Last week, Resin Designs discussed the gel seal application process. Today we will be reviewing the various connector types. Gels provide sealing on multiple types of connectors.
Gel Seal Application Evaluation While gels are actually not the best sealing solution for every situation, some applications are perfect for the automotive connector market. In order for a gel to seal any given application, it must be compatible with application features.
B-stage epoxy films are partially cured versions of a traditional epoxy resin. From a high level, b-stage films provide the same function as traditional heat-curing epoxies. Films are positioned at the bond interface, and heat is used to complete the polymerization reaction and adhere the bond.
