Product categories
Bostik produces a diverse range of adhesives and sealants, primarily categorized by their underlying technologies and intended functions. The company's core product lines include hot-melt adhesives, reactive adhesives such as polyurethanes and silicones, pressure-sensitive adhesives, and sealants, each designed to meet specific bonding and sealing requirements across various industries.[24]
Hot-melt adhesives form a key category, encompassing formulations like ethylene-vinyl acetate (EVA)/polyolefin (PO), copolyester, and polyamide variants, which provide fast-setting, thermoplastic bonding suitable for high-speed manufacturing processes. Reactive adhesives, including one- and two-component polyurethanes, silyl-modified polymers, and silicones, cure through chemical reactions to deliver strong, durable bonds resistant to environmental stresses. Pressure-sensitive adhesives adhere upon light contact without curing, offering versatility for tapes, labels, and films, while sealants, often based on butyl or hybrid polymers, focus on creating impermeable barriers against moisture and air. Water-based adhesives complement these as an eco-friendly option for applications requiring easy cleanup and low odor.[24]
In terms of functional categories, Bostik's offerings emphasize bonding solutions for structural integrity and material joining, sealing products for weatherproofing and gap-filling, and assembly adhesives that enhance manufacturing efficiency through quick application and high strength. For instance, structural methacrylates provide robust bonding in demanding assemblies, while butyl sealants excel in preventing leaks in construction joints.[24][25]
Specialized technologies within Bostik's portfolio include bio-based adhesives derived from renewable materials, low-VOC formulations to minimize emissions and improve indoor air quality, and high-performance options engineered for extreme conditions such as high temperatures or chemical exposure. These innovations, like bio-sourced hot melts and ultra-low VOC polyurethanes, support sustainability goals without compromising efficacy.[26][27]
Bostik's products serve key sectors with tailored applications: in construction, they include flooring adhesives, roofing sealants, and joint fillers for durable building envelopes; in industrial settings, such as packaging and automotive assembly, hot melts and reactive systems enable efficient production lines; and for consumer use, water-based and pressure-sensitive options facilitate DIY repairs and household bonding tasks.[28]
Key brands and applications
Bostik's portfolio includes several prominent consumer brands tailored to regional markets. Blu Tack is a reusable adhesive putty widely used for mounting posters, decorations, and lightweight items in offices, homes, and crafts without damaging surfaces.[29] Evo-Stik, a UK-focused brand, offers adhesives and sealants for DIY projects and construction, including strong bonds for woodworking, furniture assembly, and sealing windows, doors, and bathrooms.[30] Sader, a French brand, specializes in sealants and repair adhesives for home improvement, such as filling cracks, waterproofing fixtures, and bonding materials in household renovations.[31]
In industrial sectors, Bostik provides specialized adhesives for demanding applications. In aeronautics, products like fire-resistant films and contact adhesives are used for interior bonding and sealing, including wall panels, floors, and insulation to meet safety standards.[32] For the automotive industry, adhesives support component assembly, such as upholstery and carpet bonding, body panel attachment, and weatherstrip sealing, enhancing durability and efficiency in vehicle production. In 2025, Bostik launched VSR 400A, a conductive seam sealant for sheet molding compounds in heavy-duty trucks, enhancing paint adhesion and durability.[5][33] In packaging, hot melt adhesives facilitate case sealing, carton closure, and labeling, ensuring secure bonds for consumer goods while supporting sustainability goals like recyclability.[34]
Bostik's consumer and construction offerings extend to practical uses like DIY home repairs, where versatile sealants and adhesives handle tasks from gap filling to fixture installation. In 2025, Bostik introduced OB1, a universal multi-surface construction sealant and adhesive for bonding and sealing various materials in construction and home improvement projects, available in the US market. Flooring adhesives provide strong, flexible bonds for tiles, vinyl, and wood, accommodating expansion and heavy traffic. For instance, Bostik Roll-Cote, a moisture vapor control membrane for flooring applications, provides coverage of approximately 400 square feet with two coats (100 square feet per gallon total, recommended for concrete slabs in humid climates up to 99% relative humidity) from a 4-gallon pail, or 800 square feet with one coat (200 square feet per gallon, suitable for lower moisture levels of 90% relative humidity or less, or wood subfloors). Highly porous concrete may require a diluted primer coat first (500-800 square feet per gallon for the primer), which can affect overall coverage for subsequent coats. Coverage varies by substrate porosity, moisture levels, application method (such as using a 3/8-inch nap roller), surface profile (concrete surface profile 1-3 ideal), temperature, and humidity.[35] Glazing sealants, often silicone-based, offer weather-resistant joints for windows and facades, adhering to glass, metal, and masonry. These products align with broader categories of bonding solutions for assembly and waterproofing.[36][37]
Products are distributed through professional channels, retail outlets, and e-commerce platforms, with strategies adapted to regional demands—for instance, aerospace solutions emphasized in the US and construction adhesives prominent in Europe. This multi-channel approach ensures accessibility for both industrial clients and end-users.[38][39]
