Product Introduction
Momentive SilGrip™ PSA HP20 is a silicone pressure sensitive adhesive supplied as a toluene solution at approximately 61% silicone solids. Its polysiloxane gum and resin composition can be further diluted with common solvents and is compatible with SilGrip™ PSA HA20 to achieve enhanced bonding performance on low surface energy substrates such as silicone rubber and silicone foam. The adhesive is widely used in industrial pressure sensitive tape manufacturing and allows targeted peel and tack adjustments through controlled formulation and catalyst selection.
SilGrip™ PSA HP20 Features
- Excellent adhesion to low surface energy substrates such as silicone rubber and silicone foam
- Flexible formulation options to meet various bonding requirements
- Resistance to moisture, weathering, ozone, sunlight, acids, alkalis, and oils
- Colorless, high-viscosity adhesive supplied at ~61% solids
- Compatible with aromatic, aliphatic, and chlorinated solvents
- Performance adjustable through blending with SilGrip™ PSA HA20 and catalyst optimization
SilGrip™ PSA HP20 Applications
- Industrial pressure sensitive tapes on film and fabric substrates
- Bonding of silicone rubber and silicone foam components
