What is Tesa 4912?
Tesa 4912 is a high-performance, ultra-thin double-sided adhesive tape designed for precision applications requiring strong adhesion, excellent thermal conductivity, and minimal thickness. Its modified acrylic adhesive ensures strong bonding to a variety of surfaces, while the transparent PET backing allows for discreet application without obscuring the bonded surface.
Composition and Structure
- Substrate: Ultra-thin PET (polyester) film
- Adhesive: Modified acrylic adhesive
- Thickness: 5μm (ultra-thin for minimal bulk)
- Color: Transparent
- Temperature Resistance:
- Long-term: Up to 80°C (with moisture resistance)
- Short-term: Up to 140°C–182°C
- Other Properties:
- Excellent surface adhesion on curved and uneven surfaces
- High thermal conductivity for heat-sensitive applications
- Resistant to moisture, chemicals, and environmental stress
Key Properties
- Ultra-thin (5μm) for precision applications
- Strong adhesion on PC, PMMA, steel, and other surfaces
- Excellent thermal conductivity for heat dissipation
- Transparent backing for unobtrusive bonding
- Moisture, chemical, and temperature resistant
- Flexible adhesion to curved and uneven surfaces
Applications of Tesa 4912
- Thermal Component Fixing: Ideal for heat-sensitive electronics due to high thermal conductivity
- Nano Wafer Lamination: Provides reliable bonding for delicate wafer processing
- Ultra-Thin Gap Filling: Used to bond and stabilize components with minimal spacing
- Electronics Industry: Securely adheres to displays, sensors, and micro-components
- Automotive Applications: Used for lightweight assembly requiring strong, thin adhesive layers
