3M™ Acrylic Plus Tape ST1200
- 3M Product Number ST1200
- 3M ID B40071689
Details
Highlights
- Excellent for attaching weatherstrip and/or gasket seals in automotive applications
- Features two adhesives – one on each side of the tape for effective bonding
- Non-liner-side features a heat-activated adhesive for primerless bonding to ethylene propylene diene terpolymer/thermoplastic elastomer (EPDM/TPE) materials commonly used by sealing Tiers
- Liner-side adhesive is designed for adhesion to rigid clear coat systems
- Conformable closed cell acrylic foam core delivers good stress relaxation under load
- Acrylic foam core helps conform the seal to the substrate, delivers excellent wet-out
- Red 3M Branded liner is silicone-coated on one side for easy release
- Black color provides good bond-line appearance
- Supplied on a levelwound roll for process optimization
3M™ Acrylic Plus Tape ST1200 is a good choice for attaching EPDM/TPE components such as gaskets and seals. It features two adhesives, one on each side of a viscoelastic acrylic foam core, designed for robust performance even on complex contours and difficult automotive paint surfaces. A heat-activated adhesive forms an immediate bond to EPDM/TPE materials. Core provides stress relaxation when exposed to high application loads and maintains tight bond-line aesthetics under normal conditions.

For durable attachment of weatherstripping and gasket seals to rigid clear coats
Developed specifically for attaching gasket and weatherstrip seals in automotive applications, 3M™ Acrylic Plus Tape ST1200 features our heat-activated adhesive formulated for an immediate, consistent and durable bond to EPDM/TPE and other elastomeric materials without the use of an adhesion promoter, which may help OEMs meet sustainability goals. The adhesive is applied to the non-liner side of a viscoelastic acrylic foam core, which provides excellent conformability and wet-out that helps maintain seal integrity. The liner side of the core features our pressure-sensitive adhesive for bonding to a range of rigid clear coats. The black color of this OEM approved tape helps create good bond-line appearance. The red, branded 3M liner is silicone-coated on one side, suitable for heat-bond tabbing. The tape is supplied on a levelwound roll for process optimization.
1. 3M Branded liner
Easy to identify, difficult to imitate: The red, 3M branded liner on 3M™ Acrylic Plus Tapes allows customers to quickly confirm that they are receiving the 3M quality they expect from their purchase.2. Liner side adhesive
Liner-side adhesive is formulated for very high initial and final adhesion to rigid clear coats.3. Viscoelastic acrylic foam core
Exclusive to 3M, the acrylic foam core of 3M™ Acrylic Plus Tapes is engineered for stress relaxation when exposed to high stress loads, and conforms reliably even when the surface is curved or angled. This conformability helps maintain strong and consistent seal. It maintains consistent bondline aesthetics under normal stress loads. The inconspicuous black color of 3M tape ST1200 helps to ensure high satisfaction among consumers.4. Non-liner side adhesive
The non-liner side forms an immediate, consistent and durable bond to most EPDM formulations and TPE materials.Helps optimize application processes
3M™ Acrylic Plus Tape ST1200 is supplied on a levelwound roll, which provides a range of options for efficient processing including manual, semi-automated and automation-ready solutions. It can seamlessly integrate into current semi-automated and fully automated tape application processes and allows for continuous lamination to seals during extrusion and post-processing.

Frequently asked questions
There are several reasons to use tape instead of mechanical methods of attachment. Weight and system cost savings can be realized over channel or pin systems. Additionally, tape allows for more than just attachment. It also seals the backside of the weatherstrip to help block out wind, noise, moisture and dust - when used as part of an overall vehicle noise reduction program.
3M™ Acrylic Foam Tape is a high performance attachment system for all types of body side moldings, stainless steel rocker panel trim, claddings, ground effects, wind and bug deflectors, interior dash trim kits, and most other automotive accessories and trim parts. This foam tape combines high performance acrylic adhesives with viscoelastic acrylic foam cores to create products with superior initial adhesion, adhesion build and the ability to dissipate the stresses associated with most automotive applications. 3M Acrylic Foam Tape is used globally for both OEM and aftermarket weatherstrip applications and conforms to all QS9000 requirements.
3M Acrylic Foam Tapes are designed with an acrylic foam core that has unique stress relaxation properties. The acrylic foam core also adds properties such as enhanced conformability along with its superior adhesion and stress relaxation. Seals with high application stress should use a thicker tape (e.g., 1.2mm caliper) as opposed to an application with little stress (for which a thinner tape, e.g., 0.2-0.8mm caliper, may be sufficient).
3M's high performance acrylic adhesives tend to be firm and dry to the touch. They are designed to bond materials other than skin. The adhesives used are designed to give optimum performance and adhesion to automotive substrates and components. The natural oils and moisture of skin can vary from person to person and affect the "thumb appeal" of the 3M Acrylic Foam Tape. To one person the tape can feel very sticky, but to another it can feel much less sticky to the touch. The difference in "thumb appeal" is in the variation of the two individuals' skin surfaces, not the adhesive. For this reason, “thumb appeal” should not be used to measure the tackiness of the tape.
The tapes used to attach body side moldings have a pressure-sensitive adhesive on both sides of the product. Because of the surface characteristics of the rubber weatherstrip, tapes used for weatherstrip attachment use a heat-activated adhesive to achieve the maximum bond strength to the rubber without using an adhesion promoter.
There is an immediate, durable and consistent bond to the rubber when a heat-activated adhesive tape is used. With a PSA (pressure sensitive adhesive) tape, the rubber extrusion must be prepared with adhesive promoter and dried prior to laminating the PSA tape. Bond strength of tape to a rubber extrusion may not occur for several hours. Using heat-bond tapes is a one-step process (often done in-line with extrusion), does not involve the solvents found in adhesion promoters, and provides an immediate, durable, strong bond to the rubber.
There is a simple procedure that will demonstrate the bond strength. Remove the liner from the taped part and laminate a strip of anodized aluminum. When peeling the aluminum off at a 90° angle, you should witness a cohesive failure of the tape, not failure of the heat-bond adhesive to the rubber.
N1 adhesive is designed to work with neoprene and PVC substrates, while E2 adhesive is designed to work with EPDM and TPEs.
