Product Introduction
Momentive SilGrip™ PSA590 Pressure Sensitive Adhesive is a toluene-based silicone adhesive composed of polysiloxane gum and resin, supplied at 60% silicone solids. It may be diluted or blended with SR545 resin or other methyl-based silicone adhesives to adjust performance. PSA590 is commonly used for coating film and fabric substrates in industrial tape manufacturing and is especially suitable for splicing tapes due to its high tack.
SilGrip™ PSA590 Features
- Wide temperature performance with stable shear and tack up to 500°F
- Adheres well to low-energy surfaces including silicones, fluoropolymers, and polyolefins
- Resistant to moisture, ozone, sunlight, acids, alkalis, oils, and fungal attack
- Accepts fillers for custom formulations
- High tack performance ideal for splicing applications
SilGrip™ PSA590 Applications
- Industrial pressure-sensitive tapes for film and fabric substrates
