Temporary adhesive is one that is not made to withstand extreme amounts of strain, or to last for an extended period of time. Common types can include tapes, glues, and cements. Knowing when a temporary adhesive is needed and when a stronger alternative is warranted are important to understand, as using the wrong kind can have detrimental effects on a project.
One type of temporary adhesive is common white glue. This is the most familiar type of temporary glue adhesive for most people, as it is commonly found in stores and is used routinely in schools and art classes. Although the bond created by white glue is generally relatively permanent if it is not subjected to moisture, it is not strong enough to withstand much pressure. For this reason, it is best used for minor household uses and crafts.
Another type of glue adhesive is often applied to the backs of common items to create a "sticker" adhesive. Examples include bandages, patches, children's stickers, and masking tape. These can be used for a variety of purposes, both practical and entertaining, but are not recommended for use long term. Each of these can become unbounded with only minimal pressure, and are generally used to hold something in place until a more permanent solution is implemented.
Other temporary adhesives, such as rubber cement, are also considered permanent under some conditions. If the bond is put under pressure soon enough after initial contact, the adhesive won't hold and the two adjoining items can be pulled part relatively easily. Once allowed to fully set, however, breaking the bond becomes much of a hassle. To remove this type of adhesive after it has cured, special solvents may be needed.
Temporary adhesives should not be used for a long term fix. This is especially true for items that are suspended or heavy in nature, as this could result in injury or destruction of property. Once two items are fit together correctly, a long lasting and strong adhesive should be used. Examples of this type of adhesive include light-curing adhesives, which set quickly and hold strong.
Permanent adhesives should never be used in place of a temporary adhesive because they are very difficult to remove once they have been allowed to cure. Attempting to do so could result in damage to the adjoining materials. Most permanent adhesives have to be removed by using a chemical solvent, such as paint thinner.
