New Thermosil 3005, from FMi Chemical, is an all-purpose, temperature-resistant, silicone adhesive sealant for aircraft manufacturing and MRO. It offers users the ability to bond and seal parts quickly and efficiently in ambient conditions.
According to FMi, Thermosil 3005 can help lower manufacturing costs and increase throughput by reducing prep, set-up time, and fixturing requirements.
Thermosil 3005 cures to a solid state in just four hours at room temperature, delivering high peel strength with no complex curing requirements. The product achieves full adhesion in just 24 hours. Faster cure times are also attainable at elevated temperatures.
The new adhesive sealant has an operating temperature range of -65˚ to 500˚ F. It’s ideal for deep-section applications and wide-area bonding. It adheres to a broad range of clean materials without a primer and does not emit hazardous by-products.
Manufacturers use expensive work-holding fixtures to secure parts during bonding and sealing operations.
“Because Thermosil 3005 cures in four hours, it reduces the need for multiple, duplicate fixtures,” explains Nancy Daigle, FMi Chemical COO. “Rapid curing allows a single fixture to be moved to the next assembly in a short time — reducing fixturing costs and speeding production.”
Thermosil 3005 is an RTV-2 (A/B) adhesive sealant that is mixed on automated mixing equipment. It ships in ready-to-use cartridges (part A) with injector rods (part B) attached. Once mixed, the 6 or 2.5 oz cartridges fit directly into a standard pneumatic or mechanical dispensing gun.
What’s more: Thermosil 3005 can be certified to manufacturers’ specifications by FMi Chemical’s in-house, Nadcap and ANAB accredited testing laboratory.
