Component Specifications

Definition
A specialized pressure-sensitive adhesive layer applied to the back of high-precision silicone gaskets, engineered to provide immediate tack, high bond strength, and long-term durability when applied to clean, dry surfaces. This component eliminates the need for separate adhesives or mechanical fasteners, ensuring uniform contact pressure and maintaining the gasket's sealing integrity across thermal cycles, vibration, and environmental exposure.
Working Principle
The adhesive backing utilizes a viscoelastic polymer matrix that flows and conforms to microscopic surface irregularities upon application of light pressure, forming a mechanical interlock. It achieves bonding through both physical adhesion (surface wetting and penetration) and chemical adhesion (specific formulations for substrate compatibility), with a controlled peel strength that prevents gasket displacement while allowing for clean removal if required during maintenance.
Materials
Acrylic-based pressure-sensitive adhesive (PSA) on a silicone-coated release liner; thickness: 0.05-0.15 mm; adhesive formulation may include additives for UV resistance, thermal stability (-40°C to 150°C continuous), and plasticizer resistance.
Technical Parameters
  • Tack ≥ 10 N/25mm
  • Thickness 0.1 mm ± 0.02 mm
  • Liner Type Silicone-coated PET
  • Adhesive Type Acrylic PSA
  • Peel Strength ≥ 15 N/25mm (on stainless steel)
  • Service Temperature -40°C to 150°C
Standards
ISO 9001, ASTM D3330, DIN EN 1939

Frequently Asked Questions

What surfaces is this adhesive backing compatible with?

Compatible with clean, dry metals (stainless steel, aluminum), plastics (ABS, polycarbonate), and painted surfaces; surface energy > 36 dynes/cm recommended for optimal bonding.

How should the adhesive backing be applied for best results?

Clean the substrate with isopropyl alcohol, apply the gasket with firm, even pressure (e.g., using a roller), and allow 24 hours for full bond strength development before exposure to operational stresses.

Can the adhesive backing be removed without damaging the gasket or surface?

Yes, it allows for clean removal by slowly peeling at a low angle; residual adhesive can be cleaned with appropriate solvents, though the gasket may not be reusable.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
