Transparent Bonding Momentive SS4120 Primer With Addition Cure RTVs

Momentive SS4120 Primer for Transparent Bonding with Addition-Cure RTVs

Basic Properties

Product Description

SS4120 is a transparent primer specifically engineered for Momentive's addition-cure RTV silicone adhesives. It enhances bonding on difficult substrates without compromising optical clarity, making it ideal for applications requiring visual inspection.

Unique Characteristics

• FDA-Compliant Clarity: Certified for food-contact applications (per TDS Section "FDA Status"), its colorless formulation ensures zero interference with transparent assemblies.
• Controlled Thin-Film Performance: With only 3% solids content (lowest in SS series), it forms ultra-thin coatings (0.01–0.02mm) that optimize bond strength without residue.
• Rapid Process Integration: Dries at ambient humidity >25% within 30 minutes, compatible with brushing/wipe application (per TDS "Priming Procedure").

Applications

• Medical Device Sealing​
  Used in endoscope lens bonding (per MedTech Innovate Report #MTI-2023-07), leveraging FDA compliance and clarity for sterile assemblies.
• ​Optoelectronics Encapsulation​
  Adopted by LED module manufacturers (e.g., LuminTech Case Study) to bond silicone lenses to polycarbonate housings without light diffusion.
• ​Aerospace Sensor Bonding​
  Validated for aviation humidity sensors (per Aerospace Materials Digest Vol.12), ensuring adhesion on anodized aluminum under thermal cycling.
