Thermoset adhesives are polymer-based resins that are heat- and pressure-cured. Manufacturers use thermoset adhesives during heavy assembling processes or for other industrial applications. Thermoset adhesives also have properties strong enough to withstand extreme temperatures or service conditions. Heating softens a thermoset adhesive while keeping it intact, without it melting or overflowing. The thermoset adhesive hardens when cooled.
Thermoset adhesives classify as urea formaldehyde resin, resorcinol formaldehyde, melamine, phenolic, polyester and polyimide. Natural and synthetic rubbers, inorganic materials, silicone compounds, acrylics, elastomers, epoxy resins and fluropolymers contain some form of thermoset adhesive. Thermoset adhesives bond to ceramics, glass, metal, wood concrete, paper, plastic and rubber. Chemical substrates and surfaces made from wood, fiber, rubber or textiles also adhere to thermoset adhesives. The use of thermoset adhesives applies if you work with semiconductors, integrated circuits, tools, automotive parts, aerospace equipment, optical or military applications. Some medical, pharmaceutical and food processing materials also use thermoset adhesives that must be approved by the US Department of Agriculture and the Food and Drug Administration.
1. Buy high-heat resistant thermoset adhesives for bonding applications and materials.
2. Find thermoset adhesives and equipment that match your business specifications.
3. Seek thermoset adhesives from manufacturers or distributors that offer full services.
Find thermoset adhesives that resist high temperaturesHeat-cured thermoset adhesives should be flexible for different applications. They should also withstand high temperatures without melting, or have the capabilities to cool and harden without becoming brittle.
Buy thermoset adhesives that match your product or business specificationsWhether it is electronics or ceramics, it's important to find thermoset adhesives with the right bonding properties. Also, consider thermoset adhesive manufacturers that specialize in certain industries.
Seek full-service thermoset adhesive manufacturersSome thermoset adhesive manufacturers or distributors offer services for customizing your products.
- Thermoset adhesives that are designed for appliances or electronics protect against static, radiofrequency or electromagnetic interference. The features of a thermoset adhesive also protect products against fires or combustion. Materials that include thermoset adhesives provide insulation, conduction or operation in high-voltage applications.
- Physical, mechanical and thermal properties should be evaluated before buying thermoset adhesives. Gap fill, or the space between the thermoset adhesive and the surface, is an important physical property. Strength and flexibility are the mechanical components that identify thermoset adhesives. Heat transfer and use temperatures are physical properties associated with thermoset adhesives.
