Discover GIRAFE’s CL302 silicone sealant—a high-temperature-resistant, RoHS-compliant adhesive engineered for electronics, appliances, and industrial equipment. Boost durability, safety, and performance.
Why CL302 Silicone Sealant is a Game-Changer for High-Temperature Applications
At GIRAFE New Materials, we’ve spent over two decades perfecting silicone sealants for extreme environments. Our CL302 High-Temperature Silicone Sealant is a testament to this expertise, offering unmatched reliability for industries ranging from electronics to heavy manufacturing. Here’s why engineers and procurement managers worldwide trust CL302.

CL302 at a Glance
- Temperature Range: -50°C to +300°C (instantaneous resistance up to 315°C).
- Certifications: Compliant with EU RoHS and REACH regulations.
- Key Features:
✅ Exceptional adhesion to metals, glass, and plastics.
✅ Superior electrical insulation (Volume resistivity ≥1.0×10¹⁴ Ω·cm).
✅ Vibration, shock, and chemical resistance.
Where CL302 Excels
1. Household Appliances
- Electric Kettles & Microwaves: Seal heating elements and joints exposed to steam and heat cycles.
- Range Hoods: Withstand grease, moisture, and continuous 200°C+ temperatures.
2. Electronics & Electrical Engineering
- PCB Encapsulation: Protect circuits from thermal stress and humidity.
- High-Voltage Components: Dielectric strength of ≥15 kV/mm prevents arc tracking.
3. Industrial Equipment
- High-Temperature Ovens/Pipelines: Seal joints in furnaces, boilers, and exhaust systems.
- Microcrystalline Panel Bonding: Secure panels to aluminum heaters without degradation.

Real-World Success Stories
Case Study: High-Temperature Air Filter Manufacturer
A European client needed a sealant for air filters operating at 280°C. After switching to CL302:
- 50% reduction in seal failures over 12 months.
- 20% faster assembly due to quick curing.
How to Use CL302
- Surface Prep: Clean substrates with ethanol or acetone.
- Apply: Dispense evenly; align parts within 5 minutes.
- Cure: Allow 24 hours at room temperature.
Pro Tip: For high-vibration environments, pair CL302 with our MS305 Hybrid Adhesive for enhanced fatigue resistance.
Ordering & Support
- Packaging: 300 mL cartridges (24/box) or 2.6 L sausages (4/box).
