Contact adhesives are a type of pressure-sensitive adhesive applied to both mating surfaces, allowed to become touch-dry, and then bonded under light pressure. Upon contact, they form an immediate, high-strength bond without requiring clamping.
Common Sub-Types & Examples:
-
Solvent-Based Contact Cements: Neoprene or polychloroprene formulations (e.g. Evostik Neoprene Contact Adhesive)
-
Water-Based Contact Adhesives: Lower VOC alternatives for indoor applications (e.g. Bostik Aquadhere™)
-
High-Temperature Grades: Formulated to withstand elevated temperatures (e.g. oven door seals, laminating heat-resistant substrates)
-
Specialist Formulations: For bonding decorative laminates, veneers, rubber, leather or fabrics
Key Characteristics to Consider:
-
Open Time: Length of time the adhesive remains tacky before bonding (typically 5–20 minutes)
-
Initial Tack & Bond Strength: Rapid grip on contact and high shear resistance
-
Heat & Moisture Resistance: Suitability for humid or elevated-temperature environments
-
Substrate Compatibility: Effective adhesion to plastics, metals, wood, laminates and rubbers
-
Gap-Filling Ability: Capacity to accommodate slight surface irregularities
-
VOC Content & Odour: Compliance with environmental regulations and suitability for indoor use
These properties make contact adhesives ideal for cabinetry, flooring, upholstery and decorative lamination, where a fast, durable bond is essential.
