Adhesives Research’s rubber-based adhesive systems are composed of natural or synthetic elastomers that have been tackified by the addition of various resins. These cost effective adhesives have good tack and shear properties and offer good adhesion to materials with both high- and low-surface energy. These are less suited for use under prolonged UV exposure, solvent contact or elevated temperature conditions.
Adhesives Research’s acrylic-based adhesives are based on acrylic polymers. Acrylics are ideally suited for prolonged UV exposure and elevated temperatures, while offering solvent resistance and long-term stability. Acrylic systems can be formulated to have a good balance of tack, peel and shear and can be adjusted for materials with low surface energy.
Adhesives Research’s silicone-based adhesive systems combine the flexibility of silicone rubber with the temperature resistance of silicone resin. They offer the widest service temperature range, along with good resistance to a variety of solvents and to thermal/oxidative degradation. These systems have good adhesion to materials with low surface energy, but exhibit lower tack and higher cost compared to acrylics.
Adhesives Research’s heat-activated adhesive systems require a defined period of time at elevated temperatures (normally 180°F or higher) to achieve final bonding strength. Temperature, pressure and dwell time are used to affect a final cure and bond.
