Crosslinked polymeric resins called thermoset adhesives are cured by heat alone or in combination with heat and pressure. They represent a variety of different substances that, when they cure, go through a chemical reaction that results in a structure with superior strength and resistance to the environment.
Thermoset adhesives are extremely strong, have great gap-filling capabilities, and are heat- and moisture-resistant. Polyester resins and epoxy are two examples.
Although one-part adhesives are also used, the majority of thermoset adhesives are supplied as a two-component system.
Two-component adhesives typically consist of a liquid or gel-based hardener and resin that are combined to start the curing process.
One-component systems are typically supplied as pastes that must be kept cold in order to prevent heat curing. Pre-impregnated (prepreg) composites also use one-part resins. One-component systems may provide process advantages for some applications.
Epoxies are the most frequently used category of thermoset adhesives. These have a number of clear advantages in various applications.
Epoxy offers superior moisture resistance and gap-filling compared to substitutes like polyurethane adhesives when used to bind wood. Epoxy resin is additionally unusual in that it forges tight bonds with glass and metal.
Global thermoset adhesive market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
MVP Releases New Model of its Reactive Additive Manufacturing (RAM) System for Thermoset Materials.
The Reactive Additive Manufacturing (RAM) system from Magnum Venus Products (MVP), a global provider of fluid movement and production solutions for industrial applications, is introducing a new model to make thermoset materials more affordably manufactured on a medium- and large-scale.
The new RAM 48 model allows for customized build dimensions and has a print area of four by eight feet with expandable, modular four by four foot sections.
Thermosets contain polymers that undergo chemical reactions during the curing process, forming a strong bond between printed layers and giving rise to stronger, more heat-resistant products.
Due to the inherent qualities of thermoset materials, it is possible to print with open layer times and add items to the print such as heating channels or sensors to check part specifications. Another advantage is the capability to print through multiple parts at once.
