What is Tesa 61825?
Tesa 61825 is a high-performance double-sided self-adhesive tape with a black PET (polyester) film substrate and a modified acrylic adhesive system. Designed for electronic and optical applications, it offers excellent bonding strength, anti-vibration properties, and superior weather resistance. Its black appearance enhances aesthetic integration, making it ideal for high-end device assembly.
Composition and Structure
- Substrate: Black PET (polyester) film
- Adhesive Type: Modified acrylic adhesive
- Total Thickness: 250μm
- Release Paper: Transparent PET release paper, 50μm thick, 70 g/m²
Key Properties
- Strong adhesion to PC, steel, and low surface energy materials
- Excellent anti-push-out and anti-vibration performance for stable fixation under dynamic conditions
- Good bonding with low surface energy materials for broader application use
- Superior weather resistance to temperature, humidity, and UV exposure
- Black PET substrate for better optical and aesthetic integration
Applications of Tesa 61825
- Electronic equipment manufacturing: Used for bonding screens, touch panels, and other components in mobile phones, tablets, and laptops
- Optical product assembly: Ideal for fixing lenses and touch screens in optical instruments and displays
Features & Benefits of Tesa 61825
- Durable bonding strength that increases over time (PC: 15N/cm → 20N/cm, Steel: 15N/cm → 17N/cm)
- High tensile strength (73N/cm) and elongation at break (60%) for long-lasting performance
- Reliable temperature resistance (long-term up to 100°C, short-term up to 200°C)
- Black PET design enhances the visual appeal of assembled products
Comparison with Other Adhesive Tapes
- More aesthetic integration with black PET vs. standard transparent tapes
- Better anti-vibration properties than conventional double-sided tapes
- Stronger bonding on low surface energy materials compared to regular acrylic tapes
