ORP Hydroflex 64 is a redispersible powder produced by drying an emulsion of Vinyl Acetate / Vinyl Versatate / Acrylic terpolymer with PVOH as protective colloid. The specific chemical composition of the polymer allows coalescence of the redispersed polymer at low temperatures and provides good adhesion on mineral substrates.


ORP Hydroflex 64 is used to modify mixtures containing hydraulic binders. Due to its particular chemical / physical composition, ORP Hydroflex 64 improves adhesion, flexibility, hydrophobicity and water resistance of mortars containing hydraulic binders such as cement, gypsum or lime. Especially because of the flexible nature, ORP Hydroflex 64 performs very well in transverse deformation conditions.

ORP Hydroflex 64 can be used in mortar formulations where highly flexbily/elastic, hydrophobic and water resistant behavior is required at the same time.

In high performance of ceramic tile grouts formulations (CG2) ORP Hydroflex 64 can be used with the ratio of 2.0 - 4.0 % in weight and without requiring an additional hydrophobic agent. Moreover ORP Hydroflex 64 is a very suitable redispersible powder polymer for cementitious water proofing mortars.It can be used with the ratio of 7.0 - 12.0 % in weight in 1K cementitious water proofing mortar formulations. Because of its molecular structure it provides high crack bridging ability. Also ORP Hydroflex 64 performs very well in cementitious exterior plasters and topcoats with the amunt of 2.0 - 4.0 %.


Packaging: Pallet with 18 paper bags, each 25 kg, also 500 or 1000 kg of big bags.
Packages must be stored in a dry and cool warehouse. Pallets must not be stacked on top of each other to avoid caking due to the thermoplasticity of the polymer.
Packing must be closed well after usage for protection against humidity and caking. It has to be used within 6 months after the date of delivery.
