FRP composites are used to replace steel, aluminum, and wood in a wide range of applications.
Composites offer numerous advantages over other materials – lower density, lighter weight, better corrosion resistance, strength, and durability. Composites’ inherent fire resistance, strength, and ability to withstand high temperature environments with less weight than those materials have made them the product of choice for fire resistant piping, mining ventilation systems, and armored vehicles. In public transportation, they are used in aircraft interiors, fire resistant railcar and bus parts, passenger decking and walkways.
Cellobond™ Resole Resins have been designed to have low viscosity specifically to facilitate the manufacture of composites by automated processes such as VARI or Vacuum Infussion where a high degreee of fire safety, excellent mechanical properties or resistance to high temperatures is required.
Cellobond™ Resin and Catalyst combonation processes include, but are not limited to, Hand Laminations, Spray Depositiation, Warm Press Molding, Resin Transfer Molding, Pultrusion, Vacuum Injection, Vacuum Infussion, Continuous Lamination, Syntactic Foam.

Best in Class Fire at Lowest Weight
European Fire Safety Standard EN 45545 is now a reality for the rail market EN 45545-2 hazardous level depending on manufacture and vehicle design. No need for intumescent gelcoat, fire retardants, fillers
Introducing BREAKTHRU™ technology, a unique development that laboratory analysis has shown to decrease free formaldehyde to less than 0.1% versus the typical 0.3-1.5% in phenolic resins. Other potential benefits include improved honeycomb strength performance, reduced free phenol and solvent elimination, with the attendant VOC reduction.
Our phenolic novolac resins are used as curing agents for epoxy resins and as cure accelerators that promote rapid cure in resins for use in FRP composite applications.

§ Contact Bakelite Synthetics for your specific solvent requirements. Bakelite Synthetics recommends the use of a catalyst with many of our resins. Parts characteristics are contingent on proper application of the Bakelite® resins. These products are available in drum and bulk packaging. Resins and catalysts should be used in areas with good ventilation. Resins should be stored at temperatures at or below 40°F (5°C). Catalysts should be stored at 20 – 25°C, lower temperature storage can cause crystallization of the catalyst. Prior to use, the resin should be brought to room temperature. As with any resin/acid system, precise and thorough mixing of the resin and catalyst mixture is essential to achieve uniform cure and optimum quality.
