Thermoset Adhesives

Thermoset adhesives bond in different temperatures to many industrial products, surfaces and other applications
By Deneatra Harmon 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 temperatures

Heat-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.
Try: Search for thermoset adhesives according to chemistry, industry or application at Bayer MaterialScience. Hereaus develops thermoset adhesives with curing temperatures of 200 to 300 degrees F. Most of the company's thermoset adhesives are used for printing, dispensing or coating purposes.

Buy thermoset adhesives that match your product or business specifications

Whether 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.
Try: Master Bond manufactures all types of adhesives, including thermoset adhesives, for aerospace, electronics and laminating businesses. Henkel North America handles thermoset adhesives, including the Loctite brand, for the automotive, aerospace, medical and electronics industries.

Seek full-service thermoset adhesive manufacturers

Some thermoset adhesive manufacturers or distributors offer services for customizing your products.
Try: Ellsworth Adhesives offers custom packaging, labeling and documentation services for thermoset adhesives. BondPro Corporation offers services such as custom thermoset adhesive bonding, design assistance, adhesive converting and much more.

• 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.
