Silyl Modified Polymer (SMP) Adhesives for Railway Vehicles
SMP adhesives are easy to use and environmentally friendly. They have a wide range of applications. SMP is primerless on most substrates. Excellent UV resistance, easy workability, sandable, paintable and moisture resistant make SMP adhesives a smart choice.
- 70-01A – 70-01 is an excellent sealant specially developed for sealing in railway vehicles. Its low viscosity makes it easy to apply and tool.
- 70-03A | Dual, Slow Skin (SKF) – 70-03A is a high performance adhesive for bonding interior and exterior components of rail vehicles. This product is available in standard, slow skin and dual formulations. The slow skin formula allows for precision placement of substrates before fully curing. The dual formula speeds set time and cures independent of humidity. All formulations are easily extrudable and feature easy tooling.
- 70-03A FR – 70-03A FR is a high performing fire retardant adhesive for bonding interior and exterior components of rail vehicles. It offers the adhesive strength of the standard 70-03A with added fire retardant properties. Meets and exceeds NFPA 103 standard for smoke, flame and toxicity.
- 70-08A | Dual, Slow Skin (SKF) – The 70-08A is a high green strength adhesive designed for glass bonding to various substrates, and available in dual and slow skin formulations. The initial tack holds substrates in place, therefore increasing manufacturing speed. Because this product is primerless on most substrates, 70-08A is a safer choice for manufacturers.
Pressure Sensitive (PSA) Adhesives for Rail
Commonly known as a PSA, pressure sensitive adhesives offer a wide range of adhesion on many different substrates. From permanent bonds to removable adhesion, PSAs are a great choice for bonding panels, fabrics, foam and other interior products.
- F14-554 | FR – Fire retardant acrylic film with excellent peel and sheer properties. Primarily used for the retrofitting of railcar decorative laminates.
- F14-588 | FR – Fire retardant acrylic film adhesive, bonds flexible PVF and vinyl materials, excellent resistance to humidity and elevated temperatures.
- F14-610 – The Bostik 610 film exhibits excellent room temperature tack coupled with good high and low temperature performance. Designed for bonding placards, signage and decorative trim in the railway industry.
Web Adhesives
Bostik web adhesives are a heat activated, thin, fabric-like material that vary in weight between 12 – 100 grams per square yard. These products offer superior usage control to manufacturers, reducing waste from typical spray and film applications.
- PE103 – PE103 is a hot-melt polyester adhesive, with low activation temperature, excellent adhesion to textiles, vinyl and urethane foams and resists laundering.
- PA145 – PA145 is a hot-melt web adhesive that is based on a high performance polyamide polymer. It has excellent adhesion to textiles, vinyl and urethane foams and resists laundering.
- SPA110FR-A – SPA110FR-A is a hot-melt web adhesive that is based on polyamide. It bonds to urethane foams and plasterized vinyl. SPA110FR-A is formulated to aid in fire retardant constructions and has excellent resistance to plasticizer migration and laundering.
Technology – Smart Solutions
Elastic Bonding
Elastic bonding adhesives provide a flexible joint or seal that bonds individual components to a structural frame, giving it a dynamic attachment which allows expansion and contraction while maintaining bond integrity. Elastic bonds are extremely durable, making them ideal for applications where a higher-temperature structural bond would break under continuous movement and stress.
Fire Retardancy
Fire retardant adhesives inhibit the spread of flame. They aid occupant safety by reducing fire, smoke and toxic fumes, allowing railcar passengers a greater span of time to exit a high-danger situation.
Pressure Sensitive Adhesion
Commonly known as a PSA, pressure sensitive adhesives offer a wide range of adhesion on many different substrates. From permanent bonds to removable adhesion, PSAs are a great choice for bonding panels, fabrics, foam and other interior products.
Lightweight Solutions
Lightweight solutions from Bostik are essential for modern construction methods. Reducing weight in transportation vehicles translates into fuel savings and a lower overall impact on the environment. Bostik adhesives for rail offer lightweight solutions specifically formulated to decrease weight yet provide strong, lasting bonds that keep transportation moving.
SMP Elastic Bonding vs. Mechanical Fasteners
- Lightweight – Elastic bonding weighs less than mechanical fasteners such as nuts and bolts and provides a lighter bond. This allows for the use of lighter weight composite materials and a more fuel efficient on-rail performance. Challenges with the use of mechanical fasteners on composites are eliminated with the use of elastic bonding.
- Material preservation – Elastic bonding preserves the integrity of flooring materials such as fiberglass composite, phenolic composite, polycarbonate, polymeric material, carbon fiber, etc. Mechanical fasteners require drilling and risk irreparable damage. Elastic bonding reduces overall waste potential in the production process.
- Vibration – Bostik SMP products provide inherent vibration dampening and sound deadening properties, while manufacturers of mechanical fasteners are forced to insert additional layers of padding and insulation to reduce vibration and sound noise.
- Efficiency – Elastic bonding eliminates the need for multiple sizes and strengths of mechanical fasteners, thus reducing the complexity of the assembly process.
- Simplicity – Welding or fastening techniques require more specialized processes and require high paid application specialists. Elastic bonding requires less specialized processes and covers several applications. This also expands options for robotic manufacturing.
- Safety – The nature of elastic bonding maintains the originally designed operating performance of substrates over the life of the vehicle, improving long term safety. Mechanical fasteners, due to vibration and movement, can degrade substrates causing a shortened lifespan.
