3M Industrial Tapes
Equivalent to: “3M 2308 tape”, “3M 810 tape”, “3M 9448 double-sided tape”, “3M 764 floor marking tape”, “3M VHB tape” — what is different: one page explaining the 10 3M codes most used in electronics plants, genuine products with CO/CQ, anti-counterfeit labels, many widths.
Common specifications: 2308 (20/50 mm), 810 (3/4″), 9448 (7–50 mm), 764 yellow/red/white, 600.
Delivery: in stock, delivered within 24–48 hours (Ho Chi Minh City, Binh Duong, Dong Nai); lead time for bulk orders is confirmed with the quotation.
3M makes thousands of tape codes; electronics plants in Vietnam in practice keep reordering around 10 of them. The table below is arranged by the job to be done so you can pick the right one immediately and avoid buying a more expensive code than you need.

General: genuine 3M products (made in Vietnam/Thailand/China depending on the code), CO/CQ, anti-counterfeit labels, RoHS; 76 mm core; MOQ 1 box per code; carton pricing. Temperatures in the table are for reference; per 3M TDS: 471 is used in the 4–77 °C range, 764 is applied at 16–27 °C, 9448A about 70 °C long term / 150 °C short term — see the TDS table below and the datasheet for each code.
Selection by process step
– Painting/conformal coating, pad masking → 2308 (cheap) or 244 (finer).
– Double-sided bonding of small panels, labels, gaskets → 9448 (thin) or VHB (load-bearing, outdoor).
– Floor marking with forklift traffic → 3M 971 (special order); walkways, hand trolleys → 471; light or temporary lines → 764; warnings → yellow-black striped tape.
– Tape through 260 °C reflow → not one of these 3M tapes; use Kapton (TK-1033).

FAQ
– What is the difference between 2308 and 244? — 2308 is ~30 % cheaper, gives sharp lines and withstands 120 °C; 244 is thinner and removes more cleanly from fine paint finishes.
– 9448 or 9448A? — 9448A has a stronger adhesive for hard-to-bond plastic surfaces; 9448 is the general-purpose version.
– Can VHB replace screws? — For small static loads (signs, fixtures, covers) — yes; for dynamic loads — no.
– How do I recognise genuine 3M? — 3M printed core, carton label, CO; PRIMEAG photographs the labels before delivery.
Construction of a tape roll and the three adhesive families
Every tape consists of a backing (paper, plastic film, cloth, foam) and a pressure-sensitive adhesive layer; double-sided tapes also have a liner. The adhesive family determines most of the performance:
| Adhesive family | 3M examples | Characteristics |
|---|---|---|
| Rubber | 2308, 471, 764 | Instant tack, good adhesion on many surfaces; poorer heat and ageing resistance |
| Acrylic | 9448A, VHB 4910 | Ageing resistant, heat resistant, bond strength builds over time |
| Silicone | Polyimide tape, heat-resistant polyester tape | Better heat resistance than rubber and acrylic, less flow and adhesive transfer when hot |
Reading temperature figures on the TDS correctly
Each 3M code states temperature differently — always read it together with the duration:
| Code | Temperature per 3M | Interpretation |
|---|---|---|
| 2308 (crepe paper, rubber adhesive, 0.13 mm thick) | 121 °C for 30 minutes | Withstands a single short bake |
| 9448A (tissue, acrylic adhesive) | about 70 °C long term, 150 °C short term (minutes to hours) | Not for parts that are continuously hot |
| VHB 4910 (clear acrylic foam, 1.0 mm thick) | 93 °C long term, 149 °C short term | Short term: e.g. passing through a paint-curing oven |
| 471 (vinyl, rubber adhesive, 0.14 mm total) | 4–77 °C | Floor service temperature range |
Applying VHB correctly (per 3M)
- Clean: wipe with an IPA and water mixture (about 50–70 % IPA). For heavily oily surfaces: degrease first, then wipe again with IPA/water.
- Lightly abrade (180–320 grit, circular motion) surfaces that need better adhesion, then wipe off the abrasion dust.
- Primer for hard-to-bond plastics (PP, PE, powder coat, rubber): 3M Tape Primer 94 or VHB Universal Primer UV.
- Press: a minimum pressure of about 15 psi (over 100 kPa) with a roller or press — VHB adhesive is a viscous liquid and needs pressure to “flow” into the surface.
- Wait: at room temperature it reaches about 50 % strength after 20 minutes, 90 % after 24 hours and 100 % after 72 hours. Do not load-test or remove for inspection before then.
For 9448A, 3M recommends application at 21–38 °C and not applying below 10 °C; clean with IPA or heptane and press firmly after application.
Floor marking tape: choose by traffic
| 3M code | Total thickness | Per 3M |
|---|---|---|
| 764 | 0.13 mm | Light traffic, walls, pipes; not for harsh conditions, not a long-term clean-removal type |
| 471 | 0.14 mm | Medium-traffic floors, resists abrasion and solvents; removes cleanly in one piece |
| 971 | 0.42 mm | Heavy traffic, withstands forklifts and dragged pallets |
Areas with frequent forklift traffic should use a thick tape such as 971 (special order); 471 suits pedestrian walkways and hand trolleys; 764 is for temporary lines, rack locations and low-traffic marking.
Storage and common mistakes
- 3M recommends storage at about 21 °C, 50 % RH in the original carton. Best-before: 2308 within 1 year, 9448A within 24 months from the date of manufacture — use first in, first out.
- Applying VHB to an uncleaned surface or to PP/PE plastic without primer, then concluding that “VHB doesn’t stick”.
- Using 2308 for outdoor masking over several days — 3M warns that the tape can be very difficult to remove after prolonged outdoor exposure.
- Choosing tape by “strongest adhesion” rather than by temperature, surface and service time.
- Using 764 on forklift lanes — the tape wears and tears within a short time.
