ORP 7680 SL is a redispersible powder produced by drying an emulsion of Vinyl Acrylic copolymer with PVOH as a protective colloid. The specific chemical composition of the polymer allows coalescence of the redispersed polymer at low temperatures and provides good adhesion to cementitious substrates.
ORP 7680 SL is used to modify mixtures containing hydraulic binders. Due to its particular chemical/physical composition, ORP 7680 SL improves adhesion, flexibility, and water resistance of mortars containing hydraulic binders such as cement, gypsum, or lime. Especially in self-leveling mortar formulations, ORP 7680 SL provides excellent abrasion resistance, flexural & compressive strength, and good leveling.

ORP 7680 SL can be used between 1.5 – 4.0 % in self-leveling mortar formulations. This amount of usage provides high abrasion resistance, water resistance, flexural & compressive strength. It also decreases segmentation and efflorescence.
Packaging: Pallet with 18 paper bags, each 25 kg, also 500 or 1000 kg 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.
