Bonding Forever 28432420 is a heavy-duty bonding tape designed to provide a strong, permanent bond between a variety of surfaces. It is ideal for use in both indoor and outdoor applications, and can be used to bond a wide range of materials, including metal, glass, wood, plastic, and fabric.

One of the key benefits of Bonding Forever 28432420 is its strength. The tape is able to withstand a tensile strength of up to 50 pounds per square inch, making it one of the strongest bonding tapes on the market. This makes it ideal for use in applications where a strong bond is required, such as bonding metal to metal or glass to wood.

1. The surface condition determines the performance of the tape.

Before the application of the tape, the surface is exposed to various contamination such as dust,

moisture and oil. In order to maximize the adhesive performance of the tape, the surface condition

is very important. Therefore, there is a need to keep the surface clean.

☞ A cleaning agent that can be easily purchased by general consumers is ethyl alcohol.

Remove surface contaminants as much as possible with a dry cloth or cloth, and wipe the

surface several times with ethyl alcohol.

There is no slipping on the surface, and when it dries sufficiently, you may attach a tape.

※ Examples of changes in adhesion according to surface conditions

The test the change of adhesion in the external environment (fine dust concentration 70,

ultra-fine dust concentration 42).

1. Adhesive performance degradation test method

① After exposing the surface, attach the tape.

② After exposing the tape, attach it to a clean surface.

☞ When the test is carried out in ②, it is more effective as a test method for lowering adhesion performance.

▲ The graph above shows the adhesion performance according to the degree of exposure to fine dust.

Indoors, 95% level after 2 hours.

☞ After cleaning the surface, it is the same as 95% level when attaching after 2 hours

The level of 80% is expected when 4 hours have elapsed indoors, and even less than 50% is expected

if more than a day passes. Therefore, it is judged that attaching without washing does not exhibit 50%

of the adhesion performance, and it can be easily separated from the attachment site.

Outdoors, after 30 minutes, 92% level.

☞ It is 59% after 2 hours outdoors, indicating that the adhesion performance is very serious if

contaminants such as dust are not removed.

▲ The graph above shows the adhesion performance according to the degree of exposure to fine dust.

At a temperature lower than room temperature, the change in adhesive performance is more severe.

☞ Adhesive performance varies depending on the cleanliness of the surface, and temperature is also

one of the factors affecting the adhesive performance.

2. The conditions for good adhesion performance

1) As in section 1, clean the surface before attaching.

2) After removing the liner of the tape, attach it immediately. (minimize exposure time to airborne dust, etc.)

3) Attach it to the object first, and wait until the adhesive performance is maximized. (average 24h , min 1h)

After attaching, wait at least 1 hour

4) Make the surface temperature as warm as possible before attaching. (A hair dryer can be used)

Surface temperature: 25~35℃ (77~95℉) or higher (Enough to feel the warmth)

5) Requires compression after attaching to the fixed surface: 1 inch by 1 inch - 5kg or more - 20 seconds or more

Apply pressure immediately upon attachment.

A push force applied by an adult is sufficient.

6) Attachment Precautions

① Check whether there is a groove in the attachment

Groove depth 0.4mm or less: 1.1T or more applied

Groove depth 1.0mm : 1.1T not applicable, 2.0mm

or more applicable

If the groove depth is more than 1.0 mm, refrain from applying

Immediately 1hour 24 ~ 48 hour

② Consider the area of the tape by referring to the allowable weight according to the material of the surface.

For example, it can be seen that the allowable range of a tape of a certain size changes with weight.

②-1. Heavy stuff

Increase the amount of tape to be attached to make the area larger and attach it.

②-1. Light stuff

No problem even if you attach the tape wide. No problem even if you attach the tape small.

Even if a light object is attached with a small amount of tape, attach it to the four corners so that it

can be supported.

③ Applicable Exceptions.

If the load is distributed as in ②, there is no problem, but if the center of gravity is biased forward, it may

fall even after attachment.

For example, if there are different shaped objects with the same weight (Δ), the amount of tape required for

attachment is the same. As shown in the figure below, A did not fall, but B and C will.

A B C

☞ The load on an object is the product of the weight of the object and the length to the distance to the

center of gravity of the object.

a. Length to center of gravity : Aα, Bα, Cα

b. Weight of objects A, B, and C : Δ

c. Tape Thickness : β

d. The load the tape can withstand : N

e. quantity of tapes : A (4ea), B (4ea), C (2ea)

※ Do not apply tape to circular objects as much as possible. There is a risk of damage due to falling.

2xβxN < ΔxCα

the weight increases as much

as a multiple of "Cα"

C is sphere shape and not easy

to attach, so the load that the

tape can withstand is doubled

because only two are attached.

4xβxN < ΔxBα

Because "Bα" is long, the weight

increases by a multiple of "Bα"

4xβxN ≥ ΔxAα

Since the length of Aα is short,

there is little change in weight.

3. Tape Specifications for Surfaces

1) Tape Size for 1 pound

For example, a 2.0 lbs frame

① Material check: ABS

② Identify the required quantity of tape : 4ea

③ Tape size : 1in by 0.6in ; (1 in by 0.6 in) x 4ea = 2.0 lbs

④ After cleaning the surface, attach.

※ It is safe to attach a little larger than the calculated standard as shown in the diagram.
