  • Patent number: 9580630
    Abstract: An adhesive compound consisting essentially of an organic phase and inorganic phase, the organic phase comprising an amorphous aliphatic (co)polymer having a Ring & Ball softening point of between 75 and 180° C., and a second aliphatic material having a Tg of about ?5° C. or lower and a kinematic viscosity of 4500 mm2/s at 100° C. or less, wherein said organic components are present in weight amounts of between 95/5 and 10/90; the inorganic phase comprising a filler, the filler being present in amount of at least about 15 wt % in the total composition. The compositions are suitable for anti-corrosion coatings or sealants against filtration or penetration of water or moisture. A rubber material may be added to this compound or other anti-corrosion coatings to increase the yield point at high temperatures.
