About Anaerobic Adhesives and Anaerobic Sealants

Anaerobic adhesives and anaerobic sealants cure in the absence of air or oxygen. They are designed for fastening and sealing applications in which a tight seal must be formed without light, heat or oxygen. Substrate or material compatibility is an important factor to consider when selecting anaerobic adhesives and anaerobic sealants. Some products adhere to ceramics or glass, concrete or masonry, metal, paper, plastic, rubber or porous surfaces. Others are compatible with substrates or materials made from composites, textiles, fabrics, wood, rubber, or elastomers. Products that can bond dissimilar substrates such as metal to rubber are also available.

Products & Services Related to Anaerobic Adhesives and Anaerobic Sealants

Conformal Coatings

Conformal coatings encapsulate circuit boards and their electronic components in order to prevent the ingress of moisture, fungus, dust and other environmental contaminants.

Epoxy Adhesives

Epoxy adhesives are chemical compounds for joining components. They require clean surfaces and are valued for their toughness and resistance to chemical and environmental damage.

Gel Elastomers

Gel elastomers are highly viscoelastic polymer gel materials that have excellent shock absorption and damping characteristics. They are available in a variety of material types and grades.

Pressure Sensitive Adhesives (PSA) and Contact Adhesives

Pressure sensitive adhesives (PSA) and contact adhesives adhere to most surfaces with very slight pressure. They are available in solvent and latex or water-based forms.

Silicone Adhesives and Sealants

Silicone adhesives and sealants have a high degree of flexibility and a very high temperature resistance (up to 600° F), but lack the strength of other epoxy or acrylic resins.

Thermoplastics and Thermoplastic Materials

Thermoplastics and thermoplastic materials soften when heated and harden when cooled. They can withstand many heating and cooling cycles and are often suitable for recycling.

Thermosets and Thermoset Materials

Thermosets and thermoset materials are crosslinked polymeric resins that are cured or set using heat or heat and pressure. They generally have a higher resistance to heat than thermoplastics.
