588-10K and 1428 HP are equivalent to MasterFlow 928. MasterFlow 928 has both high strength and long working time. 588-10K has only high strength, whereas 1428 HP has both high strength and long working time. So, equivalence is project dependent; if only high strength is needed, 588-10K is the equivalent. If the application requires both high strength and long working time, then 1428 HP is the equivalent.
