Adhesive Bonding & Precision Adhesive Application Services

Engineered Bonding Solutions for Plastic, Metal & Electronic Assemblies

At Secondary Solutions Inc. (SSI), we specialize in precision adhesive bonding and controlled adhesive application for plastic components, electronic assemblies, and engineered products requiring durable, repeatable, and reliable bonds.

Since 1996, manufacturers have trusted SSI to apply customer-specified adhesives with the accuracy and process control needed for demanding medical, industrial, agricultural, commercial, and consumer applications.

Whether your project requires structural bonding, UV-curable adhesives, selective adhesive placement, or precision dispensing, SSI delivers production-ready solutions backed by decades of manufacturing experience.

More Than Applying Adhesive

Successful adhesive bonding requires much more than dispensing adhesive onto a component.

Long-term bond performance depends on:

• Material compatibility
• Surface preparation
• Adhesive chemistry
• Bond line thickness
• Dispensing accuracy
• Cure method
• Environmental exposure
• Assembly design
• Process control

SSI develops every bonding process around the customer's application to maximize strength, consistency, and long-term reliability.

Our Adhesive Bonding Capabilities

SSI supports a broad range of adhesive application processes, including:

• Structural adhesive bonding
• UV-curable adhesives
• Plastic bonding
• Metal-to-plastic bonding
• Plastic-to-plastic bonding
• Electronic assembly adhesives
• PCB staking adhesives
• Optical bonding support
• Thread locking compounds
• Sealants
• Potting compounds
• Customer-specified adhesive systems

Whether bonding two components or applying adhesive to hundreds of assemblies, our focus is precision and repeatability.

Operator-Controlled Precision Dispensing

Every adhesive application is different.

SSI utilizes operator-controlled precision dispensing equipment that allows experienced technicians to accurately control adhesive placement, bead size, and material volume.

This approach provides exceptional flexibility for:

• Prototype builds
• Engineering changes
• Complex part geometries
• High-mix manufacturing
• Low-to-medium production volumes
• Customer-specific application requirements
• Tight dispensing tolerances

By combining precision dispensing equipment with experienced operators, SSI delivers the consistency of controlled equipment with the flexibility required for specialized manufacturing.

Surface Preparation

Proper surface preparation is essential for achieving reliable adhesive bonds.

Depending on the substrate and adhesive system, SSI follows customer-approved preparation methods that may include:

• Cleaning
• Surface conditioning
• Precision masking
• Material verification
• Customer-specified preparation procedures
• Controlled handling practices

The right preparation process creates the foundation for long-term bond performance.

UV Adhesive Bonding

SSI has extensive experience applying UV-curable adhesives for products requiring fast cure times and precise component positioning.

UV adhesive applications may include:

• Plastic assemblies
• Medical devices
• Electronic assemblies
• Display components
• Sensor assemblies
• Optical components
• Consumer products

UV adhesives allow components to be accurately positioned before rapid curing creates a strong, durable bond.

Structural Adhesive Bonding

Many products require permanent adhesive bonds capable of replacing mechanical fasteners or supporting structural loads.

SSI supports structural bonding applications that improve:

• Mechanical strength
• Cosmetic appearance
• Vibration resistance
• Material compatibility
• Assembly efficiency
• Product durability

Our team works closely with customers to ensure proper adhesive selection and application techniques.

Customer-Specified Materials

Every application has unique performance requirements.

SSI routinely processes customer-approved adhesive systems, including:

• Acrylic adhesives
• Epoxy adhesives
• Silicone adhesives
• Polyurethane adhesives
• UV-curable adhesives
• Cyanoacrylates
• Anaerobic compounds
• Specialty engineering adhesives

We follow customer work instructions and approved manufacturing procedures to ensure every application meets its design intent.

Process Development & Validation

Successful adhesive bonding requires a validated manufacturing process.

SSI supports customers through:

• Prototype builds
• Engineering evaluations
• Process optimization
• Production validation
• First Article Inspection (FAI)
• Pilot production
• Long-term manufacturing support

Our goal is to develop repeatable processes that consistently produce dependable bond performance throughout the life of the program.

Quality Assurance

SSI incorporates quality verification throughout the adhesive application process.

Quality measures may include:

• Material verification
• Lot traceability
• Dispensing verification
• Visual inspection
• Cure verification
• Customer-specific acceptance criteria
• Functional verification when required

Our disciplined manufacturing approach helps ensure every bonded assembly performs as intended.

Integrated Manufacturing Services

Many customers combine adhesive bonding with SSI's additional manufacturing capabilities, including:

• Assembly
• Ultrasonic welding
• Spin welding
• Heat staking
• Threaded insert installation
• Pad printing
• Hot stamping
• Plastic painting
• Conformal coating
• Potting & encapsulation
• EMI/RFI shielding
• Inspection & packaging

Performing multiple secondary operations under one roof simplifies logistics, reduces lead times, and improves manufacturing efficiency.
