Product Introduction
Momentive SilGrip™ PSA529 Pressure Sensitive Adhesive is a toluene-based silicone adhesive consisting of polysiloxane gum and resin, supplied at 55% silicone solids. It can be diluted or blended with SR545 resin or other methyl-based silicone PSA systems to achieve specific performance properties. With balanced peel strength, cohesion, lap shear strength, and high-temperature holding power, PSA529 is versatile and suitable for bonding dissimilar materials across a wide range of industrial applications.
SilGrip™ PSA529 Features
- Maintains good shear and tack at intermittent temperatures up to 500°F
- Strong adhesion to metals and low-energy surfaces such as silicones and fluoropolymers
- Excellent resistance to moisture, weathering, chemicals, and fungal attack
- Elastomeric properties when cured with SRC18 catalyst
- High creep resistance for demanding industrial applications
SilGrip™ PSA529 Applications
- Industrial tapes requiring strong cohesive and thermal performance
- Bonding and fastening dissimilar materials
- Coating film and fabric substrates in PSA tape production
- Laminating and splicing applications
- Adhesive uses requiring balanced tack, peel, and cohesion
