ORP 7365 HP

Hydrophobic polymer powder

ORP 7365 HP is a redispersible powder obtained by drying an emulsion of a vinyl acetate-acrylic terpolymer with PVA as the 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 7365 HP is used to modify mixtures containing hydraulic binders. Due to its special chemical/physical composition, ORP 7365 HP improves the adhesion, elasticity and water resistance of mortars containing hydraulic binders such as cement, gypsum or lime. Especially in systems requiring water resistance as well as flexibility and abrasion resistance.

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.
