Concrete: Elastomeric waterproofing and protection - MasterSeal 6336

MasterSeal M 336 is a two component elastomeric coating, based on epoxy-polyurethane that provide longer durability to concrete structures subjected to a chemically aggressive environment combined with movements in the structures due to vibration or dilatation. MasterSeal M 336 is used in industrial process areas where concrete structures are affected by water containing dissolved aggressive chemicals. MasterSeal M 336 is also used as waterproofing membrane for water management industry, especially in areas with medium chemical aggressiveness. The system comprises: Primer: MasterSeal P770. Special primer for MasterSeal M membranes applied on mineral (dry or humid) substrates. Alternative Primer: MasterSeal P 385 Epoxy-cement primer for the application of membranes on humid mineral absorbent and non absorbent substrates. Membrane: MasterSeal M 336 Two component elastomeric coating based on epoxy-polyurethane with medium chemical resistance.
