Organic silicone adhesive is suitable for occasions requiring flexibility, wide temperature range, high frequency, high temperature and atmospheric pollution. Hot melt adhesives can be used under conditions that require fast assembly, low strength and low working temperature.
Organic silicone adhesive is suitable for occasions requiring flexibility, wide temperature range, high frequency, high temperature and atmospheric pollution. Hot melt adhesives can be used under conditions that require fast assembly, low strength and low working temperature. Acrylic adhesives are selected mainly because they have excellent electrical properties, stability, good aging resistance and transparency, and can be cured quickly. Polyurethane adhesives always remain soft, tough and strong from low temperatures to 121°C. Pre-coated polyvinyl butyral can form a tough and easy-to-assemble joint.
Adhesive applications can be found in almost all electronic devices, such as the bonding of radar antenna composite materials, which provide thermal and electrical conduction for the work of electronic components. There is also the bonding of the front cone ring of the missile.
Typical applications include:
(1) Antenna reflector used for tracking/irradiating radar in ship air defense system;
(2) The American "CobraDaYe" phased array radar system used to bond the external dielectric window to the substrate;
(3) Drilling and connecting various electronic components of the Trident MKs (Trident MKs) missile guidance computer with a thermal conductive film;
(4) In the air traffic command radar, the cured epoxy laminate is bonded to the metal frame.
