MasterCast 141

MasterCast 141 is a water-based dispersion of styrene butadiene copolymer designed for use in hydraulic binder mixtures. Used as an additive, MasterCast 141 improves waterproofing, abrasion resistance, and durability of mortars and plasters. It is also used as an adhesion agent in wet environments or immersion.

Application form

• Concrete reshaping and repair.
• Resurfacing chapes or mortars.
• Rebond between old concrete and fresh concrete.
• Exterior finishes.
• Waterproofing and lining.
• Brick and tile installation.
• Corrosion protection for reinforcing bars.

Benefits

• Rapid hardening.
• Increases flexibility.
• Reduce the withdrawal significantly.
• Prevent ressuage.
• Reduce the water/cement ratio.
• Improves the hardness and durability of mortars.
• High resistance to water penetration.
• Good abrasion resistance.
• Good resistance to freeze/thaw cycles and salt infiltration.
• Good resistance to many chemical products and mineral oils.
• Excellent adhesion to steel and concrete, with good adhesion also to brick, glass, asphalt, wood, expanded polystyrene, and most construction materials.
• Durable protection against corrosion.
• Proven performance.
• Elasticity and thermal expansion modules similar to those of concrete (unlike primary resins and resin-based mortars.).
• Not toxic: Can be used in contact with potable water.
• More economical than resin epoxy or polyester mortar.
