Specification parameters description:

Chemical Base:
Chemical base is the primary substance in the product. Adhesives with methacrylate bases are used in structural bonding applications and work well with tough-to-bond materials. Silicone-based adhesives are extremely flexible and ideal in high-heat environments. Epoxy-based adhesives are available with different resins and hardeners to bond effectively with a broad range of materials.
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.
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.
