Best Practices for 3M SJ5303
-
Surface Preparation
To obtain maximum adhesion, surfaces must be unified, dry, and free of contaminants. Surface contact is essential to adhesive performance. To maximize contact on a substrate: Clean surfaces with low strength solvent such as isopropyl alcohol (rubbing alcohol) or heptane.
Note: Be sure to follow the manufacturer’s precautions and directions for use when using solvents.
-
Application
Apply firm pressure to help increase the cold flow and contact of the adhesive with the substrate
-
Curing
Allow time (dwell) to increase the surface contact and adhesion (see illustrations below).

Shear Strength Test Methods
Shear Strength | Type | Substrate | Test Temperature | Test Method |
---|---|---|---|---|
Excellent | Dynamic shear strength | Acrylic (A-20) | Acrylic (A-20) - Used in the construction of 3M™ Bumpon Protective Product Series SJ-5200, SJ-5300, and SJ-5400, this high strength adhesive system provides excellent shear strength properties. The adhesive has the capability of providing excellent adhesion to many high surface energy substrates such as metals, ABS,_x00D_ polycarbonate, and acrylic. When adhesion is required on low surface energy/substrates (e.g., polypropylene, polyethylene, etc.), acrylic-based adhesives do not perform as well as rubber-based adhesives. | |
Excellent | Static Shear Strength | Acrylic (A-20) | 25°C | Acrylic (A-20) - Used in the construction of 3M™ Bumpon Protective Product Series SJ-5200, SJ-5300, and SJ-5400, this high strength adhesive system provides excellent shear strength properties. The adhesive has the capability of providing excellent adhesion to many high surface energy substrates such as metals, ABS,_x00D_ polycarbonate, and acrylic. When adhesion is required on low surface energy/substrates (e.g., polypropylene, polyethylene, etc.), acrylic-based adhesives do not perform as well as rubber-based adhesives. |
Excellent | Static Shear Strength | Acrylic (A-20) | 49°C | Acrylic (A-20) - Used in the construction of 3M™ Bumpon Protective Product Series SJ-5200, SJ-5300, and SJ-5400, this high strength adhesive system provides excellent shear strength properties. The adhesive has the capability of providing excellent adhesion to many high surface energy substrates such as metals, ABS, polycarbonate, and acrylic. When adhesion is required on low surface energy/substrates (e.g., polypropylene, polyethylene, etc.), acrylic-based adhesives do not perform as well as rubber-based adhesives. |
Excellent | Static Shear Strength | Acrylic (A-20) | 70°C | Acrylic (A-20) - Used in the construction of 3M™ Bumpon Protective Product Series SJ-5200, SJ-5300, and SJ-5400, this high strength adhesive system provides excellent shear strength properties. The adhesive has the capability of providing excellent adhesion to many high surface energy substrates such as metals, ABS, polycarbonate, and acrylic.
