Description
CHT AS1745T Clear RTV Silicone Sealant Adhesive is an AS1745T Sealant for electronics bonding, sealing, and assembly work where a one-part neutral-cure silicone paste is preferred. The translucent alkoxy material cures with ambient moisture and forms an elastomeric bond around sensitive substrates.
AS1745T Sealant Benefits
- One-part RTV format avoids mix ratio setup and keeps bench application simple.
- Neutral alkoxy cure is suited to many sensitive substrates used in electronic assemblies.
- Thixotropic paste stays where it is placed on vertical or uneven surfaces.
- Contains a UV tracer that helps production teams inspect coverage.
- Translucent cured appearance supports visual checks around small components and housings.
This sealant fits jobs where a silicone adhesive needs body, adhesion, and controlled placement. It can seal openings, bond components, protect wire exits, and attach parts to printed wiring board assemblies. Apply to clean, dry substrates and size the bead so the material can cure through the section. Deep beads and enclosed cavities need process review because moisture-cure silicones cure from the outside inward.
Common Applications for AS1745T Sealant
- Sealing electronic module openings, covers, and housings.
- Bonding components on printed wiring board assemblies.
- Flexible strain relief around leads, terminals, and small fixtures.
- Industrial assembly work where a non-slumping silicone paste is easier to place.
Compatible Materials and Processing Notes
- Published CHT data references compatibility with copper, brass, steel, aluminium, and FR4.
- Use clean surfaces and confirm adhesion on the exact production substrate.
- Allow enough humidity exposure and time for the bead depth used in the assembly.
- Use the UV tracer as an inspection aid when the process includes UV viewing.
