Cure Time:
Cure time is the length of time it takes for the adhesive to completely dry or harden. Different cure times may determine the best application method of the adhesive. Since most polyurethane adhesives cure quickly, dispensing machines are ideal in these applications. Light curing adhesives require light sources within specific wavelengths to cure where the strength of the light source affects cure time. Depending on the particular adhesive, temperature and humidity greatly increases or decreases the actual cure time. Many acrylic adhesives cure quicker than epoxies.
Exact Working Life:
For two-part adhesives, working life refers to the duration of time the adhesive must be used once the two parts are mixed and before the adhesive sets. An adhesive's working life varies from a few minutes to several hours. An adhesive with a long working life is commonly used to bond large objects and for setting varied parts. Working life is also referred to as worklife and pot life.
Material Compatibility:
Material compatibility lists which materials the product fills. Acrylic adhesives are suitable for use on a wide range of materials including wood, ceramic, fiberglass, metal, and plastic. Contact adhesive is typically used on wood, drywall, concrete, and vinyl. Methacrylate adhesives are compatible with metal, acrylic, PVC, and gelcoat. In addition to material compatibility, other factors may determine the best type of adhesive for a certain application such as brittleness, flexibility, and the adhesive?s resistance features.
Mix Ratio:
Mix ratio is the required relative proportion of epoxy resin to hardener. Two-part epoxy adhesives cure based on a chemical reaction. If the proper mix ratio is not achieved, the epoxy will not reach its optimal state. Improperly mixed epoxy may form a weaker bond or fail to harden. The most common ratio is 1:1 because of the ease of mixing and relatively quick cure time. Higher mix ratios, including 2:1 and 3:1, may be ideal in applications that benefit from longer cure times, such as the need to reposition items.
