ORP Thermobond 45

Redispersible polymer powder for dry mortars

About the product:
ORP Thermobond 45 is a redispersible powder prepared by drying an emulsion of a vinyl acetate/VeoVa/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 Thermobond 45 is used to modify mixtures containing hydraulic binders. Due to its special chemical/physical composition, ORP Thermobond 45 improves the adhesion, elasticity and water resistance of mortars containing hydraulic binders such as cement, gypsum or lime.

Areas of use:
ORP Thermobond 45 can be used in mortar formulations where good flexibility, elasticity and thixotropic properties are required.

External Thermal Insulation Systems (ETICS):
ORP Thermobond 45 can be used to make cementitious compounds applied to EPS and XPS boards in thermal insulation systems.
The recommended dosage is 1.0 - 3.0%.

Adhesives for EPS and XPS boards in thermal insulation systems:
recommended dosages: 0.5 - 2.0%.

Storage and shelf life:
Packing: pallet with 18 paper bags, each 25 kg, and also packing of 500 or 1000 kg in big bags is possible. Bags should be stored in a dry and cool place. Pallets should not be stacked on top of each other to avoid caking of goods due to the thermoplasticity of the polymer. The packaging must be closed to protect against moisture and powder sticking. The recommended period of application is 6 months after the date of delivery.
