PSA550 Silicone Pressure Sensitive Adhesive

SS-PSA550 Low Viscosity Silicone Pressure Sensitive Adhesive which dries to a low tack.
It has an overall balance of peel strength, cohesion, lap shear strength and high temperature holding power.
This versatility makes this product useful in a wide variety of applications, even for the fastening and bonding of dissimilar materials.
PSA silicone adhesive may be applied and heat cured on high speed laminating lines or at room temperature in a broad range of fastening applications.
PSA 550 silicone adhesive has exhibited good adhesion to many difficult to bond substrates.
It is ideal for the bonding of silicone-coated material, silicone strips and foam.

PSA550 may be applied by brush, roller or any suitable coating device.
- Thinning if required may be done with suitable solvent.
Both surfaces to be bonded should be thoroughly cleaned with a suitable cleaning solvent and the adhesive should be applied to them and allowed to dry either
in room temperature or at an elevated temperature.
- The length of drying time will depend on the solvent used, adhesive thickness and temperature it is exposed to.
  - The recommended adhesive thickness is between 1 to 4mm.
After the solvent has completely evaporated from the adhesive, the surfaces to be bonded should be firmly pressed together and the adhesive should be allowed to cure. For the recommended solvent please contact Silicone Solutions 01204 863290
Typical cure rates at room temperature (21°C to 25°C) will require 3-7 days for the catalysed adhesive to develop maximum strength.
- The cure time can be shortened by elevating the temperature to a maximum 165°C.
- A typical shortened cure cycle is 24 hours at 25°C followed by 24 hours at 100°C.
