What makes FAST different from ordering directly through STM?

Answer:

FAST is built specifically for specialty trade professionals who need stocked, ready-to-ship products in smaller pack sizes with fast checkout and rapid fulfillment.

While STM serves large OEM and industrial accounts with contract pricing and custom converting, FAST focuses on:

  • Stocked SKUs only
  • Smaller trade-friendly pack quantities
  • Quick online ordering
  • Faster shipment turnaround
  • No minimum order contracts

It’s professional-grade adhesive performance — delivered with trade speed and convenience.

How fast do orders ship?

Answer:

Most in-stock FAST orders ship within 1–2 business days from our U.S. facility.

Transit time depends on location and carrier selection, but the majority of customers receive orders within 2–4 business days.

Tracking information is automatically sent once your order ships. If timing is critical, contact us before placing your order and we’ll confirm availability.

Are these the same tapes used in industrial manufacturing?

Answer:

Yes. FAST products are manufactured by Specialty Tapes Manufacturing (STM), a U.S. producer supplying demanding industrial and OEM environments.

The difference is packaging and fulfillment model — not performance.

You receive the same adhesive technology trusted in manufacturing, converting, and production applications, packaged in quantities that fit specialty trade workflows.

What if the product doesn’t work for my application?

Answer:

We understand adhesive selection can be application-specific.

If you’re unsure before ordering, contact us with details about:

  • Surface materials
  • Environmental exposure (heat, moisture, UV)
  • Load or performance expectations

If you’ve already purchased and experience an issue, contact us within 30 days. We’ll review the application and determine replacement or return eligibility. Unused, resalable products may be returned per our return guidelines.

Our goal is long-term trade partnership — not one-time transactions.
