Description

With the growing use of bonding technology in industry and professional trades, and the resulting, increasing demands on the quality and durability of glued products, comprehensive national and international standards have been developed for, amongst other things, the characterisation, classification and testing of adhesives and adhesive bonds. Zircono-aluminates are patented technology. They are polyvalent and are suitable as adhesion promoters for water-based paints, solventborne paints and rubber applications. In this case, since it is an entirely newly manufactured bumper, use a wet on wet filler to optimise time and profitability in the repair. Adhesion Promoter 4298UV is a liquid promoter used to improve the adhesion of 3M™ Acrylic Foam Tapes to low surface energy plastics such as thermoplastic olefins (TPO), thermoplastic urethanes (TPU), and polypropylene (PP).

In automotive coatings, the term adhesion promoter refers to the primer, which achieves adhesion of the subsequent paint layer to thermoplastic polyolefin (TPO) substrate. This adhesion promoter is usually comprised of chlorinated polyolefin (CPO) as the active adhesion-promoting component, other resins, and pigment.The silane additive must be able to diffuse or migrate to the inorganic substrate and react at the interface. Effective coupling action with silanes as additives depends on several criteria: Examples of the inorganic type are the chromate conversion coatings that were previously used extensively in aerospace industries for prebond surface treatment of aluminum. These act as both corrosion inhibitor and adhesion promoter. Today, these chromate conversion coatings have fallen from favor due to toxicity issues. There are many types of adhesive available and they are often developed with a specific use in mind. As a result, what could be perceived as a disadvantage of a particular adhesive type in some applications could be its advantage in another. Therefore, it is essential to use a glue that appropriate for the application at hand. Characteristics of adhesives that can be disadvantages in certain situations include: Good mechanical dispersion of the silane into the formulation will assure uniform coupling and best efficiency. Silicone (Si) is the center of the silane molecule, which contains the organofunctional group (RO) and a second functional group (X).

Follow the specifications of the product’s technical data sheet in terms of drying time, gun adjustment, etc. Examples of the organic type include coordination complexes of trivalent chromium chloride and carboxylic acids. The most notable is Volan, manufactured by DuPont as a fiberglass finish. In any case, the addition of the filler will reduce the elongation at break, the flexibility and in many cases the toughness of the polymer because the fillers will be present up to very high levels. (E.g. ATH; 20% Polymer, 80% Filler). Adhesion Promoter Composition: The chemical and physical properties of the CPO can also have a significant effect on adhesion performance. Addition of co-resins to CPOs can enhance adhesion, reduce blistering and improve the appearance of coatings applied over the adhesion promoter layer. CPOs have limited compatibility with most resin types, but unlike conventional coatings, this may not be detrimental to performance. CPOs promote adhesion best when they are at the interface of the substrate and the coating applied over the substrate. As main functionality or because of their side effects, some other types may be used as adhesion promoters:

Solvent-based and water-based coatings, Alkyd, Epoxy, Melamine, Phenolic, Polyester, Polyurethane, Rubber) The reactivity of the TiO bond can cause problems with discoloration in the presence of phenols in some instances, but this disadvantage would seem to be more than offset by the positive aspects of titanates as coupling agents. In terms of commercial usage, however, the titanate coupling agents appear to have some way to go to match up to their potential and significantly displace silanes. According to IUPAC, adhesion is the "process of attachment of a substance to the surface of another substance". Interactions between the adhesive and substrate have a very short range of less than one nanometre. Therefore, good wetting of the materials to be joined by the adhesive in its liquid state is required to produce a high quality bond. In addition to the wetting ability, the adhesive and substrate must have compatible molecular groups so that interaction between the adhesive and substrate can take place and thus achieve adhesion. Hermann Onusseit: Practical knowledge of adhesive technology. Volume 1: Basics. Hüthig, 2008, ISBN 978-3-410-21459-5. Along with other bonding techniques, some adhesives and related materials needed for the bonding process (such as solvents for cleaning, primers, etc.) are hazardous substances and require appropriate handling precautions.

At the other end of the chain is an inorganic functionality that is especially compatible with a given substrate In the former case the promoter is used generally as a solution in a suitable solvent (e.g., methanol, ethanol, and isopropanol) or solvent mixture. After the primer is applied and allowed to dry, excess material can be gently wiped-off or rinsed-off with alcohol. The silane layer is then cured for 5-10 min at 110°C or for 24 hrs at ambient conditions.The level of CPO used in the formulation will be dependent upon the substrate, coating type and required performance properties. There are a number of ways to promote adhesion for adhesives and sealants to adhere well to other materials. The main mechanisms of promoting adhesion are:

The aqueous chemistry of zirconium is complex and dominated by hydrolysis. One aspect is that polymerization takes place when salt solutions are diluted. The polymeric species can be cationic, anionic, or neutral. Polymers that are formed include ammonium zirconium carbonate, zirconium acetate, and zirconium oxychloride. Zirconate coupling agents have very similar structure to the titanates. They also perform similar functions. Zirconium compounds exist in both water and organic solvent soluble forms. Like the titanates, zirconate coupling agents are useful in improving the dispersion characteristics of fillers in polymer systems. Examples of zirconate coupling agents and their applications are given in the table above.

In surgery, adhesives are used in the treatment of certain surgical wounds. These adhesives are usually based on fibrin, the natural adhesive substance that causes blood to clot when bleeding. Since fibrin occurs naturally in the body, it has the advantage that the adhesive is not rejected by the body. In addition, over time it degrades naturally by itself, which eliminates the need for elaborate after-treatment such as removing stitches. This property is especially important for surgery on the heart or the gastrointestinal tract. Among these classes organo silane adhesionpromoters have secured a prominent position in the market. Titanate and zirconate adhesionpromoters are less well-recognized compounds that also perform as coupling agents and / or adhesion promoters.
