ORP Thermobond 74 is a redispersible powder produced by drying an emulsion of Vinyl Acetate / Acrylic copolymer with PVOH as a protective colloid. The specific chemical composition of the polymer allows coalescence of the redispersed polymer at low temperatures and provides good adhesion on mineral substrates.
ORP Thermobond 74 is used to modify mixtures containing hydraulic binders. Due to its particular chemical/physical composition, ORP Thermobond 74 improves adhesion, flexibility, and water resistance of mortars containing hydraulic binders such as cement, gypsum, or lime. Especially because of the flexible nature, ORP Thermobond 74 performs very well in transverse deformation conditions.

ORP Thermobond 74 can be used in mortar formulations where good flexibility/elasticity, recovery, and thixotropic behavior is required.
Packaging: Pallet with 18 or 30 paper bags, each 25 kg (450 or 750 kg), also 500 kg of big bags.
Packages must be stored in a dry and cool warehouse at temperatures between 10 – 25°C. 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. It has to be used within 12 months.
