ORABOND™ UHB03110GWith an Ultra High Bond

Description
ORABOND™ UHB03110G Series tape consists of a gray foamed acrylic pressure sensitive adhesive designed for high
performance bonding and mounting applications. The elastomeric nature of the foamed adhesive makes it ideal for
applications requiring conformability and where thermal expansion differences are of concern.

Application Instructions
At ORAFOL we are interested in the successful application of our pressure-sensitive adhesives by our customers. The
following notes are intended to provide suitable support for customer-specific application tests. In all cases, in case of
uncertainties, please contact your ORAFOL representative. (www.ORAFOL.com)
Preparation/Cleaning To achieve optimum adhesion, all surfaces must be free of loose materials, e.g.
dust or other particles. It is important to remove any oil, grease or aqueous
films. For example, the “ORAFOL Cleaner” (a mixture of isopropanol and water)
can be used, with the use of lint-free disposable towels if possible. After
cleaning, the surface energy can be measured with Dyne Test Pens. More
persistent contaminants may require the use of stronger / alternative cleaners
such as heptane or other solvents.

and Design Parameters
Some materials do not provide an adequate surface for adhesion even after
proper cleaning and require surface pretreatment. This can be done via
physical methods (roughening or flaming the surface) or by chemical methods
(e.g. pickling).
By using the adhesion promoter ORABOND™ UHBPrimerA (or B with UV
indicator), better adhesion, stronger initial bond strength and better adhesion
below 15 °C can be achieved, especially for high-shear ORABOND™ acrylic
adhesives. IMPORTANT: Only use adhesion promoter on the adhesive areas!
For this purpose, the corresponding area can be demarcated with masking tape
(for example ORATAPE® MT95). For glass bonding in outdoor applications, we
recommend using the silane-based UHBPrimerG.
Pressure-sensitive adhesives develop their specified adhesive forces from a
defined contact pressure. The amount of pressure depends on the desired
initial tack, the adhesive used, and its width and thickness. For a 10 mm wide
ORABOND™ tape, roll weights between 2 and 7 kg at 10 mm/s are used. The
pressure can be checked with chalk pencils or a transparent mating part.
An average room temperature of approx. 21 °C / 70 °F is recommended for
bonding. Special low-temperature UHB™ grades and the use of the
ORABOND™ UHBPrimerA / B can be helpful for colder conditions and
substrates. Condensation on the surface should be avoided at all costs.
Depending on the design and temperature, ORABOND™ UHB™ pressure
sensitive adhesives require some time to achieve full adhesion, ranging from
24-72 hours at 21 °C / 70 °F. Preheating surfaces and using the UHBPrimerA /
B reduce the time to full adhesion.
The following design parameters apply to our ORABOND™ UHB™ Acrylic
Foam Adhesive Tapes: For static loadings, peel and splitting forces must be
avoided. For tensile or tensile shear loadings: 60 cm² adhesive tape per 1 kg
static load. UHB™ systems can compensate for 300% of their thickness with
thermal expansion. For joint gap tolerances, these systems can compensate for
50% of the tape thickness per metre, provided these tolerances are not in the
form of steps or edges.
