3M™ Tape Primer 94
- Enhances adhesion of 3M tapes
- Ideal for low surface energy materials
- Improves bond strength, consistency, and long-term durability
Product Description
3M™ Tape Primer 94 is a high-performance adhesion promoter designed to enhance the bonding strength of 3M tapes to a wide variety of substrates. This versatile primer is specially formulated to improve adhesive performance on difficult-to-bond surfaces, ensuring more reliable, durable, and long-lasting tape applications across industrial and general-use settings.
By preparing and conditioning surfaces prior to tape application, 3M™ Tape Primer 94 helps increase bond consistency and adhesion strength, particularly on low surface energy materials. It is effective on substrates such as polyethylene, polypropylene, ABS, and PET/PBT blends, as well as more common materials including concrete, wood, glass, metal, and painted metal surfaces.
Easy to apply, the primer forms a thin, uniform coating that promotes optimal adhesive contact without significantly altering the appearance of the surface. It is widely used in automotive, construction, electronics, and manufacturing industries where strong and dependable tape adhesion is critical for performance and longevity.

| Flash Point Flash Point The flashpoint of a solvent is the lowest possible temperature at which it can vaporize to form an ignitable vapor. Flashpoint is often confused with “autoignition temperature”, which is the temperature at which a solvent ignites without an ignition source. | -20 °C |

| Viscosity Viscosity Viscosity is a measurement of a fluid’s resistance to flow. Viscosity is commonly measured in centiPoise (cP). One cP is defined as the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP. A product like honey would have a much higher viscosity -around 10,000 cPs- compared to water. As a result, honey would flow much slower out of a tipped glass than water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application | 1-10 mPa.s |
