3M GPH · HIGH-TEMPERATURE BONDING
3M GPH tape for bonding before powder coating
3M VHB GPH is a grey, double-sided acrylic foam tape for bonds exposed to high temperatures. The series can be considered for joining parts before powder coating; the substrate, temperature profile and load on your bond determine suitability.
01
Selection criteria
Which GPH version fits your temperature process?
First establish the temperature the bonded parts will face, for how long, and whether they are joined before powder coating. The GPH series is described for short-term exposure up to 230 °C and long-term exposure up to 150 °C; these values do not replace a check of your specific process.
Both surfaces, bonding area and required tape thickness also matter. GPH-060GF, GPH-110GF and GPH-160GF differ in thickness. The soft acrylic foam conforms to slight surface roughness and can relax stress.

3M GPH selection guide
Select GPH for surface, load and powder coating
3M describes GPH for substrates with high or medium surface energy, including stainless steel, polyamide, PMMA and ABS. That does not establish suitability for every plastic or coating. Clean, dry surfaces free of condensed moisture are important during application; the manufacturer’s data sheet gives an ideal application temperature range of 21 °C to 38 °C.
For an assessment, tell us both parts, any coating, bonding area, load, and the temperature and duration in service and during coating. Krückemeyer GmbH can supply suitable double-sided tapes as application-specific cut lengths or die-cut parts; we assess material suitability and geometry with you. See 3M VHB for other systems and tape cutting for a suitable supplied format.

Questions about 3M GPH
When can 3M GPH be considered for bonding before powder coating?
The GPH series is described for bonds made before powder coating that subsequently pass through high temperatures. The manufacturer’s data sheet distinguishes short-term exposure up to 230 °C from long-term exposure up to 150 °C. For your application, the temperature profile, dwell time, parts and load need to be considered together. A temperature rating alone does not establish that the finished bond is suitable for your coating process.
Which surfaces does 3M name for the GPH series?
3M names materials with high or medium surface energy. Examples include stainless steel, polyamide, PMMA and ABS. Adhesion also depends on the actual surface and its preparation; the parts should be clean, dry and free of condensed moisture. These statements do not provide a general GPH approval for low-surface-energy plastics. Please tell us about both materials and any coatings so that the tape choice can be assessed for your bond.
How do GPH-060GF, GPH-110GF and GPH-160GF differ?
The three versions differ in thickness according to the manufacturer’s data sheet: GPH-060GF is 0.60 mm, GPH-110GF is 1.10 mm and GPH-160GF is 1.60 mm. All belong to the grey, double-sided GPH series with soft acrylic foam. The right thickness depends on joint geometry, surface roughness and load. Do not choose by temperature rating alone; also assess how the bond behaves under peel and shear loads.
What information does Krückemeyer need for a GPH cut or die-cut part?
Tell us the required shape or width, both parts and surfaces, and the intended assembly step. For bonding before powder coating, include the temperature profile, duration and subsequent load. Krückemeyer GmbH makes die-cut parts from double-sided film and foam tapes; a cut format can adapt handling to the application. We assess whether a GPH version is suitable for the material and geometry you need.
