Royal Aerospace Sealants

Aerospace sealing materials for fuel tanks, fuselage structures, access doors, pressurized areas, aerodynamic surfaces, and other aircraft sealing applications.

Cyberbond

Instant-bonding adhesive products used for rapid assembly of metals, plastics, elastomers, and other engineered substrates.

Vibra-Tite

Threadlocking, retaining, sealing, and related fastener-assembly products used in industrial manufacturing, maintenance, transportation, and equipment applications.

ND Industries

Fastener-locking and sealing materials for threaded assemblies, retaining applications, and industrial fastening processes.

Hardman

Engineering epoxy adhesives and EPOCAP potting and encapsulation products for assembly, repair, casting, electrical protection, and industrial applications.

CILBOND

Bonding agents and primers for rubber, polyurethane, friction materials, and other polymer-to-substrate applications.

SILAPRENE

Flexible elastomeric sealants and contact adhesives for transportation, industrial manufacturing, and related assembly applications.

Aerospace Sealants

Royal aerospace sealants support aircraft fuel tanks, floorboards, access doors, cabin pressurization areas, aerodynamic surfaces, fuselage structures, and other sealing applications. The WS range includes polysulfide systems with different cure rates, densities, application characteristics, and qualification profiles. Product selection should consider the exact aircraft application, specification requirements, working time, application class, fuel or fluid exposure, joint geometry, and maintenance process.

Structural Adhesives

H.B. Fuller structural adhesive products include methacrylate and epoxy systems for bonding metals, composites, plastics, and other engineered substrates. MMA adhesives are especially relevant where rapid strength development, production speed, gap filling, or multi-material bonding are important, while epoxy systems provide additional options for rigid structural attachment, repair, and demanding industrial service.

Instant Adhesives

H.B. Fuller cyanoacrylate adhesives support fast-fixturing assembly of metals, plastics, rubber, elastomers, and other small bonded components. These products are particularly relevant to high-volume manufacturing and MRO applications where rapid bond formation, controlled viscosity, small bond lines, and simplified dispensing are important.

Threadlockers & Retainers

H.B. Fuller's fastener-assembly portfolio includes threadlocking and retaining products used to secure threaded fasteners, cylindrical assemblies, bearings, bushings, gears, and other fitted components. These materials are relevant to manufacturing and MRO operations where vibration resistance, controlled removal, gap filling, cure behavior, temperature, and service fluids influence product selection.

Potting & Encapsulation Materials

H.B. Fuller EPOCAP products include two-component epoxy materials for potting, encapsulation, casting, and related electrical or industrial protection applications. Different formulations address general-purpose processing, flame-retardant requirements, automated dispensing, long working windows, fuel resistance, low shrinkage, and other specialized performance needs.

Industrial Sealants

H.B. Fuller industrial sealants include flexible elastomeric materials for transportation, equipment, durable-goods, and general industrial assembly. These products address joints where movement, vibration, weather exposure, moisture, or dissimilar materials make a flexible seal preferable to a rigid adhesive bond.

Bonding Agents & Primers

CILBOND bonding agents and primers are used to chemically bond rubber, polyurethane, friction materials, and other polymers to metal or other prepared substrates during molding and curing. These materials support automotive, aerospace, transportation, marine, petrochemical, and industrial components where the bond must withstand demanding thermal, chemical, and dynamic service conditions.
