Aerospace applications demand materials that can perform under pressure—literally. From extreme temperatures and high-stress loads to chemical exposure and long operational lifespans, every component must deliver reliable, long-term performance. This is where Syensqo’s line of Dapco™ sealants and adhesives makes a measurable difference.
Engineered for advanced composite systems and sealants, Dapco™ products support the rigorous demands of the aviation and aerospace sectors. Learn more about these adhesives, their benefits for aviation and aerospace applications, and how authorized Dapco™ distributor Integral Products meets flight-critical needs with these advanced adhesives.
Why Aerospace Relies on Advanced Adhesives
Aircraft and spacecraft are exposed to very high and very low temperatures, internally and externally, along with physical shock and vibration, jet fuel and chemicals, and other operating conditions. If these are not accounted for during construction of the craft, the results can be failed adhesives, malfunctioning equipment, and grave danger to occupants. As a result, the adhesives and sealants used in aircraft must be up to the challenges of flight.
Dapco Adhesives for Aerospace
Formerly sold under the Solvay and Cytec™ names and now part of the Syensqo product family, the Dapco™ line of advanced adhesives are developed for high performance in applications from sealing firewalls to bonding heat shields, panels, and other critical components reliably. They include:
- Dapco™ 2100: Primerless firewall sealant.
- Dapco™ 2200: Quick-drying firewall sealant.
- Dapco™ 1-100 Chemical Primers: Improves bond strength of most RTV silicone systems.
- Dapco™ 18-4F Silicone Firewall Sealants: Used as a coating, sealant, or filleting material.
- Dapco™ 3008N Low-Density Honeycomb Fillers: Low-density and self-extinguishing for potting, stiffening, and edge filling.
- Dapco™ 2900 Two-Part High-Temperature Silicone Sealants: Adds thermal insulation and is resistant to hydraulic fluid and engine oil.
- Dapco™ 3003 Epoxy Adhesives with Repair Compound: Structural epoxy adhesive with excellent chemical resistance.
- Dapco™ 3300 and 3301: Clear, two part silicone adhesive for bonding rubber and RTV compounds to metal, glass, or plastic; 3301 has slightly higher viscosity.
Key Applications in Aerospace Systems
Dapco™ adhesives and coatings are trusted and reliable for many different uses in aircraft construction and operation. Some of the most common include:
- Firewall sealant: Protects sensitive equipment from fire and excess heat.
- Heat shielding: Adds a layer of thermal insulation in heat-exposed assemblies and compartments.
- Strengthening honeycomb panels: Adds strength and stability to honeycomb material used in aircraft floors, walls, and bulkheads.
- Filler: Fills gaps and open spaces in composites during aircraft construction.
- Joint sealant: Reinforces joints between panels and components.
- Maintenance and repair: Patches and bonds damaged materials.
