Pressure sensitive adhesives outperform their canned and contained brethren by injecting a powerful element of versatility into the adhesive archetype. The single or double-sided material employs a backing medium equipped with a sticky coating, a combination that excels as an all-in-one answer to bonding. No water or heat is needed to prompt the sticky material to grip a surface. Only a slight pressure is called for, a pressing of the tape until it bonds to the target surface, conforming to the contours of the object as it sticks.
Classed as a practical and user-friendly approach to the issue of bonding, pressure sensitive adhesives have parted company with classical canned and tubed glues in favour of a ready-to-apply profile, a format that infuses adhesion technology with enhanced versatility. To clarify, substrate-equipped tapes vary their formulations to fulfil numerous adhesion strategies. Certain products target temporary bond issues, pressing on as a fastening agent for a label or sticker. Postage stamps and mailing labels identify with this class of temporary adhesion. Permanent formulations equip the tape or film with a powerful sealing capacity, creating a bond that’s heat and chemical resistant. Two-sided variants need little explanation. A powerful adhesive is typically layered on both sides of this format to create a strong hold on a heavy object, a purpose typically reserved for mechanical fasteners. One example of this double-sided material is a slice of tacky tape that fixes a rear-view mirror on to a windscreen, a task that no fastener could match without modifying the windscreen glass.
Up until a handful of years ago, choices were limited in the PSA (Pressure Sensitive Adhesive) market. The carrier material, the physical backing, offered more options than the actual substrate, with paper, plastic, and fabric-reinforced alternatives rounding out the bulk of the PSA family. Frustrating sticky layers came off and stuck to the applied surface, negating the temporary adhesion claims of the product. The new generation of PSA products on the market today incorporate a host of next-generation attributes. Primer substrates ensure the product comes off cleanly. Permanent bonding solutions use special formulations with enhanced cohesion agents, thus varying the tackiness and viscosity of the substrate to maximize bonding energy within extreme environments.
Versatility and fast bonding stand apart as the headliners of easy-to-apply contact adhesives, but these characteristics are growing at an exponential rate to encompass new features. Determined to create must-have appeal in every domain, industrial to commercial, these products incorporate weather sealing options, foam inserts, noise dampening variants, and web-strengthened backing materials that expand to match the movements of surface joints.
