ORP 7680SL

Redispersible polymer powder for self-leveling screeds.

ORP 7680 SL is a redispersible powder obtained by
drying an emulsion of vinyl acetate/VeoVa/acrylic terpolymer with PVA as protective colloid. The special chemical composition of the polymer promotes bonding of the redispersed polymer at low temperatures and ensures good adhesion to cementitious substrates.

ORP 7680 SL is used to modify mixtures containing hydraulic binders. Due to its special chemical/physical composition, ORP 5680 SL RD improves the adhesion, elasticity and water resistance of mortars containing hydraulic binders such as cement, gypsum or lime.

Particularly in self-levelling screed formulations, ORP 7680 SL provides excellent abrasion resistance, flexural and compressive strength, and good leveling properties.

Properties:
Appearance: white powder
Chemical composition: vinyl acetate-acrylic terpolymer
Stabilizing system: PVA
Residual moisture (%): Max. 1.5
Density (g/l): 400 - 600
Ash residue (%): 12 ± 2
Alkali resistance: high
After dispersion with water: 1:1
pH level: 6.0 - 7.0
Minimum film forming temperature (ºС): 5

Areas of use:
ORP 7680 SL can be used in self leveling screeds at a dosage of 1.5 - 4.0%. This amount provides high abrasion resistance, water resistance, flexural strength and compressive strength. It also reduces the formation of efflorescence.

Storage and shelf life:
Packing: paper bags of 25 kg. 18 bags per pallet. Big bags 500 kg.
Bags should be stored in a dry and cool warehouse at a temperature of 10 - 25 ° C. It is not advisable to stack pallets one on top of the other in order to avoid caking due to the thermoplasticity of the polymer. The package must be closed after use to protect against moisture and caking.
The minimum storage period is 12 months.

Before using this product, we advise you to carefully read the Safety Data Sheet.
