摘要: A composition which contains (a) 80 to 99% w of a bitumen component; (b) 1 to 20% w of an elastomer; (c) 1 to 60% w of a hydrocarbon resin which has been modified to contain carboxyl, carboxylic anhydride, hydroxyl and/or amino groups; and (d) 1 to 100% w of an inorganic filler, the weight percentages being based on the total weight of the bitumen component and elastomer, is suitable for coating structures and a process for applying the composition at elevated temperature onto a suitable structure.
