ORP 7099 RD
Introduction:
ORP 7099 RD is a redispersible powder obtained by drying an emulsion of a vinyl acetate / VeoVa / acrylic terpolymer with PVA as a protective colloid. The special chemical composition of the polymer facilitates the bonding of the redispersed polymer at low temperatures and ensures good adhesion to cementitious substrates.
ORP 7099 RD is used for modification of mixtures containing hydraulic
binders. Due to its special chemical / physical composition, ORP 7099 RD improves the adhesion, elasticity and water resistance of mortars containing hydraulic binders such as cement, gypsum or lime.

Storage and expiration date:
Packaging: 25 kg paper bags. 18 bags per pallet. Big bags of 500 kg.
The bags should be stored in a dry and cool warehouse at temperatures between 10 - 25 ° C. It is not advisable to stack pallets one on top of the other to avoid caking due to the thermoplasticity of the polymer. The packaging should be closed after use to protect it from moisture and caking.
The minimum shelf life is 12 months.
