Bostik 70-03A FR adhesive/sealant is the first SMP based technology that is tested to the flame, smoke and toxicity requirements in accordance to the NFPA 130 standard. Bostik 70-03A FR is specially developed for mass transit industry to comply with the interior and exterior sealing requirements of vehicles. This product demonstrates the mechanical properties necessary for elastic bonding, suitable for elastic constructions in industrial applications. SMP based Bostik products are solvent, isocyanate and silicone free and have an excellent UV, weather and temperature resistance. These products exhibit a very good adhesion performance on a wide variety of substrates (limited or no pre-treatment necessary).
FEATURES
- Compliant with NFPA 130 standard for flame, smoke and toxicity
- Non-Halogenated
- Solvent, isocyanate and PVC-free
- Very good UV-resistance and aging properties
- In general, good adhesion on several substrates without the use of a primer
- Permanent elastic within temperatures from
- Neutral, odorless and fast curing
APPLICATIONS
- Interior and exterior sealing in train constructions that require fire retardancy
- Elastic bonding in mass transit constructions (e.g. train, bus & coach)
- Interior sealing in aerospace applications
- Sealing welded seams
