Water Activated Tape
(Gummed Tape)

•  Universal Closure System for Variety of Applications - Dirty, Dusty, Recycled & Reused Cartons; under/overfilled; freezer/cold applications
•  Easy Identification Through Custom Printing


Masking Tape

Masking tape has a wide array of applications, temperature ranges, surface characteristics, and it is not limited solely to painting. When Masking tape is used for painting, it provides clean lines and can be easily removed without destroying the material it has been applied to.
There are lots of applications besides painting for masking tape. Here are a few:
•  Powder Coating
•  Sandblasting
•  Identification and Marking
•  Bundling


Strapping or Filament Tape

Strapping Tapes have reinforcements of tensilized polypropylene (TPP), polyester yarn or glass yarn filaments, with a variety of tensile strengths and adhesive types, including: natural rubber, synthetic rubber, modified synthetic rubber, and clean removal.

A variety of grades of strapping tape are available. Some have as much as 600 pounds of tensile strength per inch of width. Different types and grades of adhesive are also available.


Bonding Solutions

Like liquid adhesives, Bonding Tapes are often used to replace fasteners for joining structural and non-structural parts, to reduce costs, weight, and corrosion problems.

Tapes have several advantages over liquids, including the fact that they can be bonded to both low-surface-energy (LSE) and high-surface-energy (HSE) substrates. They can also be cut exactly to fit the dimensions of a part, and used for fixturing an assembly.

When choosing between liquid adhesives and bonding tapes, the decision-making process can get a bit complicated. Both types are highly versatile and can do a lot of the same jobs, so in many assemblies either will work. Sorting out the advantages of each for a given application starts with looking at the two main types of differences: process and performance.

The first consideration is the process. What parts are being joined, what materials will be used (the substrates), will the process be automated or will assembly be done by hand, how much time is available between initial joining and handling and ultimate bond strength? A process advantage of tapes is their immediate holding strength. They often can be pre-applied to one of the surfaces to speed final assemblies.

Adhesives, on the other hand, tend to allow parts to be repositionable during assembly, if exact placement is an issue. Tapes often are quicker to apply and more precise in their application. Adhesives maybe able to cover a larger surface more quickly however. Generally, adhesives can be easier to automate, since there is not a liner to remove or pressure to apply.

The second variable is performance. Tapes provide a clean application with a uniform thickness between the substrates. Tapes can be designed to have high elongation which can provide flexibility at the joint, absorbing vibrations and impacts.

Since the ultimate strength of the joint depends on the application, in many applications tapes can easily replace screws, rivet and welds providing a cleaner, more “finished” appearance. The performance advantages of adhesives over tapes can be summed up as a wider range of strengths, plus their curing chemistries can attain higher performance than most tapes for structural applications.

Tapes are also limited in how thick they can get so they're not as good as liquids for gap filling.


Bonding Tapes

Bonding Tapes provide a durable bonding solution with a high degree of conformability, gap filling, and stress relaxation properties. Bonding Tapes will enhance appearance, improve performance and process. These tapes have pressure sensitive adhesive on two sides to bond substrates with strength that range from permanent to permanently repositionable. Bonding Tape works on a wide range of substrates from metal to paper.

Applications

•  Replace spot welds, screws, rivets & liquid fasteners
•  Create a gasket where metal fasteners are used
•  Metal to Glass Bonding
•  Door Glass Bonding
•  Decorative Trims
•  Glazing
•  Name Plates & Sign Construction

Applications

•  Replaces metal fasteners and alleviate rust
•  No adhesive cure time
•  High conformability and extremely high internal strength
•  Excellent weather resistance & durability
•  Reduced risk of leaking - from drilled holes
•  Smoother, more aesthetically pleasing finished product - no unsightly screw heads
•  Provides vibration dampening and moisture barrier




Adhesives

Adhesives can come in a variety of forms, such as liquids, aerosols, hot melt glue sticks, one and two part epoxies, pastes and others. They can be applied in a variety of ways, such as: sprayed, spread, troweled, extruded, mixed and others.

Adhesives are generally described in two ways, based on their applications:

•   Structural Adhesives are used when the application needs 1,000 psi or more of overlap shear strength, such as when used for assemblies in transportation like aircraft wings or truck trailers.

•   Non-Structural Adhesives are used for less critical bonding applications such as closing cartons and applying labels.


Structural Adhesives

Structural Adhesives refer to relatively strong adhesives. These adhesives join different structural type materials together easily and effectively. It performs similarly to welding but it offers much more flexibility.

Adhesive bonding offers many benefits that include bonding of dissimilar materials. Structural Adhesives also provide thermal and electrical insulation of a joint. They also offer protection against galvanic corrosion of different metallic materials joined together.

Furthermore, adhesive bonding joins different materials together without adding weight to the material preserving the load carrying capacity of the material. The bonding adhesives also offer improved structural appearance without disturbing surface modifications. Moreover, these adhesives require little heat for curing and thus, they do not affect the dimensions, shape or metal properties.

Common examples of Structural Adhesives include epoxies, cyanoacrylates, and certain urethanes and acrylic adhesives.




Non-Structural Adhesives

Non-Structural Adhesives ("Non-Structural" does not mean weak) are generally used to bond materials in cushions, gaskets, insulation, veneers, decorative trims, packaging, paneling, countertops, furniture, woodworking and general assembly.

Non-Structural Adhesives are often used in the form of pressure sensitive tapes, transfer films or hot melts. They do not have the temperature capabilities or environmental durability as do structural adhesives. However, they generally provide an instantaneous bond due to their pressure sensitive or hot melt characteristic.

Non-Structural Adhesives are generally used for interior applications, although many new products are seeing exterior applications as well.
