TEKNOPRIME 840 is an advanced copolymer dispersion which, when used as an admixture for sand and cement mixes, produces a high strength waterproof patching mortar, screed or render. It can also be mixed with cement to produce a slurry for sealing porous and absorbent substrates.
For polymer modification of sand and cement mortars to provide enhanced mechanical characteristics: When mixed with cement, can be used as a primer and a bonding agent for polymer mortars, renders and screeds. Can also be diluted with water to produce a primer for deck and roof applications in the clean water industry.
• Excellent adhesion in dry, damp or permanently wet conditions to both concrete and steel.
• Higher compressive and tensile strengths.
• High abrasion resistance.
• Low water permeability.
• Enhanced resistance to freeze-thaw cycles, alkalis and dilute acids.
• WRAS Approved for use in contact with potable water.
