When engineers need a pressure-sensitive adhesive that delivers excellent adhesion, high initial tack, and consistent performance across metals, plastics, and foams, the 3M™ Adhesive 300 family is often the first choice.

This medium-firm acrylic adhesive system appears across a wide variety of transfer tapes—including the 927, 950, 950EK, 9458, 9471, 9472, 9671, 9672, and 9674 constructions—each offering different liners, thicknesses, and handling characteristics to support converting and manufacturing needs.

At NEDC, these materials are part of our everyday workflow. We provide custom die-cutting, lamination, slitting, and part fabrication for every adhesive in the 300-series lineup, supporting applications from aerospace and defense to medical devices and industrial equipment.

What Makes 3M™ Adhesive 300 Unique?

3M™ Adhesive 300 is a versatile medium-firm acrylic designed for:

• High initial tack and strong holding strength

• Excellent adhesion to metals, painted surfaces, and many plastics, including low-surface-energy materials

• Clean die-cutting and reliable converting behavior

• Good outdoor, chemical, water, and temperature resistance

It can withstand temperatures up to 250°F short-term, 150°F long-term, and cold environments down to –40°F.

This combination makes the adhesive an industry standard for nameplates, overlays, foam gaskets, and industrial bonding.

Performance Capabilities

The Adhesive 300 series is known for:

Strong Peel Adhesion

Adhesion values increase dramatically as the adhesive wets out over time. Thicker versions often show the highest peel strengths across metals and plastics.

Environmental Durability

• Minimal impact from humidity

• Maintains or increases strength after water exposure

• Suitable for outdoor UV exposure

• Stable through temperature cycling

• Resistant to oils, mild acids, and alkalies

These characteristics make Adhesive 300 a dependable choice for demanding environments.

---

Common Applications

These materials are widely used for:

• Graphic overlays and nameplates

• Rating plates and metal tags

• Automotive interior and exterior bonding

• Medical device assembly

• Electronics mounting and internal fastening

• Foam gasket lamination

• Custom die-cut adhesive components

NEDC frequently laminates these adhesives to foams, films, and customer-supplied substrates to create multi-layer assemblies ready for installation.
