( View Selector Guide )
Reduce Production Cycle Times and Cost
- Primerless adhesion elimates primer application time and open time window conerns.
- Adheres to all firewall materials: Stainless steel, titanium, aluminum, epoxy coatings, polysulfide and silicone sealants, EPDM/fluoro/silicone rubber seals.
- Rapid-tack-free allows part movement within two hours, significantly reducing cycle times.
- Mixed frozen stable for 4 months (DAPCO™ 2100 & 2200).
- Mixed room temperature stable for over 4 months (DAPCO™ 2100 & 2200)
- Unused portions can be capped and used later, dramatically reducing cured sealant waste and cost (DAPCO™ 2100 & 2200).
- Reduce number of stock items due to robust application versatility.
- Rapid repair version allows 4 hour fly away in AOG situations (DAPCO™ 2200).
Reduce Environmental Release and Improve Shop Safety
- Primerless adhesion elimates primer VOC exposure and emissions.
- Solventless formulation reduces VOC exposure and emissions.
- Low odor.
- Neutral cure does not induce corrosion.
Reduce Number of Sealants Stocked due to Application Versatility
- Primerless adhesion to many other substrates: EMDM & rubber, nylon, thermoplastics, composite materials, acrylic, polycarbonate and more.
- Compatible to other materials - no cure inhibition.
- Shop friendly and cost effective.
- Mixed room-temperature-stable for more than 4 months (DAPCO™ 2100 & 2100).
Capitalize on Completed Performance Testing
- Proven catastrophic fire protection (>3 minutes at 3500ºF >15 minutes at 2000ºF)
- Boeing approved to BMS 5-63 with FAA authorization. (FAR 25)
- Good resistance to aerospace fluids.
- Repairability to itself, other silicone and polysulfide sealants.
- Approved to SAE/Military - AMS 3374 firewall sealant specification.
- Being used on JPATS, JSF, Boeing commercial airplanes.
- Extensive test results are available for review.
Rapidly Expanding Applications
- Fillet, faying surface and fastener sealing in extreme condition areas.
- Engine cowles, struts, auxiliary power units, ducting.
- Commercial airplanes, military jets, helicopters, regional airplanes.
- Aerosmoothing of exterior sections exposed to high temperatures.
- Insulative coating on panels and ductwork in areas where high temperatures are possible.
