Both Side Tape Company is a manufacturer of Double Sided Foam Tape For Automotive Decorative Trim Strip, made for light decorative trim installation on painted metal body panels and ABS/PC plastic trim backs. It is used for door trim, window trim, narrow exterior strips, and small decorative automotive parts that need a neat bond line, firm initial tack, and stable adhesion after dwell. For reliable use, IPA cleaning, about 15 psi / 100 kPa pressure, and 24-72 hours edge observation are recommended before rain or car wash exposure.

Product Overview
This automotive decorative trim strip tape is built for narrow trim bonding where the adhesive layer should stay clean, slim, and stable. It is suitable for painted metal surfaces and molded ABS/PC plastic trim backs, especially on door trim and window trim that follow a flat or slightly curved vehicle surface. The foam layer helps fill small surface gaps, reduce minor vibration noise, and improve contact without visible screws or clips.
On prepared sample panels, typical 180 degree peel adhesion can reach 18-28 N/25 mm on painted metal and 15-25 N/25 mm on ABS/PC plastic, depending on surface condition, pressure, and dwell time. These are reference values, not absolute guarantees, because vehicle paint systems and molded plastic materials can vary.
Foam thickness should match the trim shape. A 0.4-0.8 mm tape is usually better for flat, low-profile decorative strips where the edge must remain neat. A 1.0-1.5 mm tape is more suitable for slight curves, minor backside ribs, or small gaps that need stress absorption. If the foam is too thin on a curved part, the center may bond first while the ends lift later. If it is too thick on a narrow flat strip, the bond line may look raised.
Before application, both bonding surfaces should be cleaned with IPA to remove wax, oil, polish residue, dust, hand marks, and mold-release residue. For aged paint, low-surface-energy plastic, or trim ends with higher lifting risk, a primer option can be tested before batch use. After firm pressure, the tape gives useful initial tack, while final adhesion normally develops during a 24-72 hours dwell period.
Benefits
- Helps install decorative trim strips on painted metal without drilling, clips, or visible fasteners.
- Bonds to painted body panels and ABS/PC plastic parts after IPA cleaning and proper pressure.
- Offers 0.4-0.8 mm thickness for flat trim and 1.0-1.5 mm for slight curves or small gap compensation.
- Acrylic adhesive supports outdoor parking, humidity, rain exposure, and normal car wash spray after full dwell.
- Closed-cell foam helps reduce small vibration noise and improves contact on minor uneven surfaces.
- Primer testing can be used for difficult plastic backs, aged paint, or trim ends with lifting risk.
- Edge lifting can be checked at both ends, corners, and curved sections after 24-72 hours.
What should be checked before applying tape to automotive decorative trim strip?
Before applying the tape, check the surface condition, foam thickness, and trim shape together. The painted metal area should be dry and free from wax, silicone, polish, oil, and dust. The plastic trim back should also be cleaned because hand oil or release agent can reduce adhesive wet-out. A pressing pressure of about 15 psi / 100 kPa can be used as a reference to improve adhesive contact. For uncertain paint systems or plastic backs, compare primer and no-primer samples, then observe the ends and curved areas after 24-72 hours.

How does curved surface stress affect decorative trim strip bonding?
Curved surfaces can create hidden stress, even when the trim strip is lightweight. When a molded plastic strip is pressed onto a curved painted metal area, the foam must absorb small gaps, trim rebound, and outdoor temperature movement. A thinner foam can keep a flat strip neat, but it may not give enough contact on a curved section. A slightly thicker foam can improve stress relaxation, but it should not make the trim edge look bulky. A practical sample test should check both ends, corners, and curved areas after 24-72 hours, then observe again after rain or controlled car wash spray.
FAQ
Q1: What trim parts is this tape designed for?
It is designed for door trim, window trim, narrow exterior decorative strips, and small ABS/PC plastic automotive parts.
Q2: Should the surface be cleaned before bonding?
Yes. IPA cleaning is recommended to remove wax, oil, polish residue, dust, and mold-release contamination.
Q3: When should primer be tested?
Primer can be tested on difficult plastic backs, aged painted surfaces, or trim ends where lifting risk is higher.
Q4: How long should the tape dwell before rain or car wash exposure?
A 24-72 hours dwell period is recommended as a typical reference before strong water spray or washing.
