SikaLatex®-141
(former MasterCast® 141)
WATER RESISTANT BONDING AGENT AND MORTAR ADMIXTURE
SikaLatex®-141 is a (SBR) styrene-butadiene co-polymer latex specifically designed for use with cement compositions. It is used in mortar and concretes as an admixture to increase resistance to water penetration, improve abrasion resistance and durability. It is used with cement as a reliable water-resistant bonding agent.
The use of SikaLatex®-141 synthetic latex in cement-based slurries and mortars compensates for many deficiencies in the mixes without detracting from their inherent strength and properties.
SikaLatex®-141 has been developed specifically for use with Portland cements. As ordinary mortar dries out, voids are left which make it permeable and weaker. When SikaLatex®-141 is added, the SikaLatex®-141 particles bind together to form continuous films and strands - these stitch the opposite sides of the voids together and block up the spaces, increasing strength and resistance to water penetration. SikaLatex®-141 combined with cement produces an excellent adhesive; each component compliments the properties of the other in this respect.
Suitable for use in hot and tropical climatic conditions.
- Earlier hardening.
- Improved flexibility.
- Reduced shrinkage.
- Prevents bleeding.
- Lower water-cement ratio.
- Increased durability and toughness.
- Resistance to water penetration.
- Good abrasion resistance.
- Good frost resistance and resistance to salt permeation.
- Good resistance to many chemicals and to mineral oil.
- Excellent adhesion to steel and concrete. Adheres well to brick, glass, asphalt, wood, expanded polystyrene and most building materials.
- Prolonged corrosion protection.
- Similar thermal expansion and modulus properties to concrete (unlike resin mortars and primers).
- Non-toxic.
- More economical than epoxy or polyester resin mortar.
