ORP 7680 SL: Redispersible Powder for Self Leveling Dry-Mix Mortars.
ORP 7680 SL is a redispersible powder polymer produced by drying an emulsion of Vinyl Acetate / Acrylic copolymer with PVOH as protective colloid.
The specific chemical composition of the polymer ORP 7680 SL 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 and 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 levelling mortar formulations ORP 7680 SL provides excellent abrasion resistance, flexural & compressive stength and good leveling.
ORP 7680 SL IS A REDISPERSIBLE POWDER POLYMER FOR SELF LEVELLING DRY-MIX MORTARS
TYPICAL PROPERTIES
Appearance: White powder
Chemical composition: VA / Acrylic Copolymer
Stabilizing System: PVOH
Residual Humidity (%): Max. 2.0
Bulk Density (g/l): 400 - 600
Ash Content (%): 12 ± 2
Alkali Resistance: High
After 1:1 Dispersion with Water
MFFT (°C):5 ± 1
APPLICATION AREAS
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. Also decreases segmentation and efflorescence.
PRODUCT HANDLING – STORAGE – SHELF LIFE
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.
ORP 7680 SL has to be used within 6 months after the date of delivery.
