Tacky tape

Tacky tape is a butyl-based vacuum bag sealant giving high elasticity and tenacity. It has exceptional sealant properties, eliminating the risk of imperfect seals often fi>und in the initial phases of vacuum bag application, so improving the vacuum efficiency and reducing labor. It is suitable for polyester, vinyl ester, and epoxy laminating systems. 

Apply the sealing tape, which is a double-sided tacky tape for adhering to the mold surface and the vacuum bag together, surrounding the preform assembly. 

Tacky tape (cleaning) A sticky (high tack) surface used to clean particulates from surfaces without leaving a significant amount of residual chemicals. See also Strippable coating. 

Another important application area for PSAs in the electronic industry focuses on the manufacturing, transport and assembly of electronic components into larger devices, such as computer disk drives. Due to the sensitivity of these components, contamination with adhesive residue, its outgassing products, or residue transferred from any liners used, needs to be avoided. Cleanliness of the whole tape construction becomes very critical, because residuals like metal ions, surfactants, halogens, silicones, and the like can cause product failures of the electronic component or product. Due to their inherent tackiness, acrylic PSAs are very attractive for this type of application. Other PSAs can be used as well, but particular attention has to be given to the choice of tackifier or other additives needed in the PSA formulation. The choice of release liner also becomes very critical because of the concern about silicone transfer to the adhesive, which may eventually contaminate the electronic part. 

Terpene monomers are another class of interesting natural monomers because they give, on polymerization, hydrocarbon therplastic resins that exhibit a high degree of tackiness useful in pressure sensitive tapes [25]. They are also used for sizing paper and textile materials. Terpene-phenol resins are effective heat stabilizers for high-density polyethylene. 

Working with less dilute solutions of elastomers one cannot fail to notice the influence (the stiffer the greater the effect) of molecular structure on the onset and course of non-Newtonion flow, on gelation and swelling, and the influence of the solvent as expressing itself by virial coefficients, molecular dimensions in solution, spinnability, and film forming. The sensitivity with which the tack of adhesives, demonstrated by pressure sensitive tapes which at that time reached the market, depends on the structure and composition of the elastomer was similarly striking and raised the question, which molecular structure or state was best suited to exhibit tacky adhesion, or adhesion per se. 

Polyisobutylene fractions of particular molecular weights are very tacky and are used as adhesives for pressure-sealing tapes. 

The final thickness of epoxy tape or film adhesives is on the order of 5 to 15 mils. These adhesives may be soft and tacky, or stiff and dry, depending on their formulation. The soft and tacky products are valuable in products requiring application to contoured or vertical surfaces. If the product is especially tacky, a release liner (e.g., polyethylene film, coated paper) is generally used to keep the film from blocking. The stiff and dry products are generally used for flat surfaces where speed and ease of application are required. 

Burgundy pitch. A resin obtained from Norway spruce or European silver fir. Other types, e.g., that from various species of pines, are also offered under this name. Characterized by extreme tackiness, soluble in acetone and alcohol. Used to some extent in surgeons tape and various special adhesive compositions. 

The adhesive is manufactured in tape form by a hot-melt process. It is a tacky solid at room temperature. The integrity is maintained by using a finely woven glass fabric scrim as the carrier. This process is an excellent example of the compromises required in the technology of formulation. Some of the high-temperature performance that is expected from the phenolic resole is sacrificed for the improved bond strength and toughness afforded from the epoxy resin. The filler is added to make the thermal coefficient of expansion of the cured adhesive more metallic in nature. Dicyandiamide is the... 

Another advantage of the reduction of the cohesive strength of the adhesive might also be seen in the persistence of the tackiness, which could be similar to the principle realized in pressure-sensitive adhesives, e.g., tapes [23]. 

Pressure sensitives are contact-bond adhesives. Usually rubber based, they provide a low-strength, permanently tacky bond. They have a number of consumer applications (e.g., cellophane tape), but they are also used in industrial applications where a permanent bond is not desirable or where a strong bond may not be necessary. The adhesive itself is applied rapidly by spray. Assembly is merely a matter of pressing the parts together. 

These organic solvent-based adhesives are very easy to apply and find wide application in general industry. Whenever a variety of different materials has to be stuck together quickly and easily, organic solvent-based adhesives will often be the answer. The footwear industry uses them for sticking soles to uppers and many other operations. The automotive industry uses them for stick-on trim and a variety of other jobs. Foam-seat manufacturers use these adhesives in brushable and sprayable form. Paper converters employ solvent-based permanently tacky adhesives in the manufacture of labels and sticky tapes. 

Variety of forms Rubber-based adhesives can be supplied to the user in solvent or water-based formulations, as a solid hot melt or a soft tacky extrusion, as a tape (reinforced or not, single or double-sided), as a film, and even pre-applied to a surface for later solvent or heat activation. Products can be single or multiple component, depending on the application requirements. 

Early adhesive uses of butyl rubber generally consisted of solvent-based dispersions, or tape and rope extrusion of formulated solid rubber. Extensive use was made of butyl rubber s inherent tackiness in highly saturated grades of the polymer to make pressure sensitive tapes and precoated films. The polymers are also extensively used as major components of hot-melt adhesives, solid rubber sealing tapes, and caulking grades of sealants and mastics, of which most were high solids content solvent-based formulations. 

This natural resin is used in adhesives, e.g., adhesive tape, epilating wax, and as a tacky wax to prevent slipping (violinists, gymnasts). It is a residue after distilling oils from certain pine trees. Gum rosin and wood rosin are the two main types. They contain abietic acid which may be the sensitizer. Cross-reactions between rosin and balsam of Peru occur (Fisher 1973, p. 173 Hjorth 1961).
