Armaflex 520 Adhesive is based on modified chloroprene rubber in a blend of flammable solvents. The material has low viscosity for ease of application and quick drying characteristics. In the dry state, Armaflex 520 Adhesive is not flammable. The adhesive is particularly suitable for joining Armaflex flexible elastomeric insulation and for bonding the material to clean prepared surfaces. When properly cured the adhesive maintains the resistance to water vapour expected of Armaflex. The adhesive may also be used to apply Armaflex Sheet Insulation to flat or curved metal surfaces that will operate at temperatures up to 180°F (82°C).  Meets Military Specification MIL-A-24179A and Amend-2 as Type II, Class 1. Dried film also meets 25/50 flammability and smoke developed index requirements of codes and specifications when tested by ASTM E 84 Method.  520 Adhesive will make a resilient and heat-resistant bond with many materials where the use of a solvent-base neoprene contact adhesive is suitable and desirable. It will make a strong resilient bond for sealing laminated aluminum foil and kraft paper vapor-retarder jackets. Contact us today to find out more.
