SilGrip™ PSA345SM is an additive for acrylic and rubber PSA emulsions that improves temperature resistance and adhesion to low energy surfaces.
SilGrip™ PSA345SM is a silicone emulsion that is designed to be used as an additive in acrylic and rubber pressure sensitive adhesive formulations. SIlGrip™ PSA345SM improves adhesion, high temperature shear resistance, and clean release of pressure sensitive adhesives. to low energy surfaces like polyolefins and silicone release liners.
Silicone Solids: 25%
Viscosity @25° C: 11
pH: 4.8
Residue Solvent: Odorless Mineral Spirits
Primary Chemistry: Silicone Adhesive
Increased initial adhesion to difficult surfaces
Improved high temperature shear resistance
Clean removal
Excellent anchorage to polyolefin films
Repositionable
Effective at low addition rates (0.5-2.0%)
Poor adhesion of acrylic and rubber adhesives to low energy surfaces.
Sticky residue left behind by adhesives.
Poor resistance of adhesives cured with BPO to high temperature shear.
SilGrip™ PSA345SM is recommended to be added directly to pressure sensitive adhesives at 0.5-2.0% based on adhesive solids. Through mixing is recommended. If further enhancement of properties is required up to 10% of SilGrip™ PSASM can be added. If improvement of lap shear is desired, small amounts of SilGrip™ PSASM can be catalyzed with 2.0% benzoyl peroxide and combined with the adhesive.
