High-Performance Single-Component Polyurethane Resin
The perfect binder for white or light-colored pebbles.
This resin has been specifically formulated to ensure an impeccable result in various applications. Thanks to its high gloss and transparency, and low viscosity, it offers a flawless, clear, and bubble-free result. Ideal for use as a binder for white or light-colored pebbles. Due to its optimal mechanical performance, it ensures an extraordinary result for creating continuous permeable floors that are durable and aesthetically pleasing.
Consumption for Aggregate/Pebble Binder
Depending on the chosen grain size, consider these indicative data for polyurethane resin for white or light aggregates:
- 7-10 mm – for 20-25 kg of aggregate, add 500g of polyurethane resin;
- 4-6 mm – for 20-25 kg of aggregate, add 650g of polyurethane resin;
- 2-4 mm – for 20-25 kg of aggregate, add 800g of polyurethane resin;
- 1-2 mm – for 20-25 kg of aggregate, add 1.2 kg of polyurethane resin;
Note: It is advisable to verify the necessary amount of binder before application, as an excess of binder can cause swelling and foaming. The correct amount of binder is just enough to wet the surface of the aggregate without dripping. If you have any doubts, contact our support!
These consumption rates are calculated based on the standard sale format of aggregates/pebbles, approximately 20-25 kg per bag.
Primer
For greater adhesion security, use Transparent Epoxy Resin as a primer for your surfaces: in this application, consider 150-200 g/m² applied with a simple roller; to ensure optimal grip, sprinkle quartz sand to refusal immediately after application.
Resistance
Excellent mechanical performance, with pebbles perfectly bound together and extraordinary resistance to yellowing.
Main Features
- High transparency
- Excellent mechanical resistance
- Good chemical resistance and carbonation resistance
- High impregnation and reinforcement of technical fabrics
- Long working time
- Glossy and self-leveling surface
- High UV resistance for long-lasting creations – no yellowing
- High mechanical resistance for scratch protection
- Low viscosity reduces the presence of air bubbles after curing and facilitates carbon fiber impregnation
- Odorless and solvent-free
- Perfectly transparent and bubble-free thanks to its specific formula.
Curing Time
Complete curing is achieved in about 24 hours.
Surface Preparation
Apply on solid, compact, dry substrates that are not subject to capillary rising damp, clean, and free of oils and greases. Treat surfaces by shot blasting or sanding followed by residue vacuuming. Alternatively, a cementitious underlay or epoxy screed is recommended. The use of a suitable primer is recommended (see specific application cycle sheets).
Product Use
Mix the product with colored or monochromatic mineral aggregates of any grain size, using manual (low-speed drill with helical mixer) or automatic (concrete mixer) mixing. For a finished product with maximum chemical and mechanical resistance, use aggregates that are clean of oils or greases and free of moisture. The ratio of aggregate to binder is highly dependent on the shape, size, and porosity of the aggregate; as a guideline:
- 40:1 for 4-6 mm aggregate;
- 20:1 for 2-4 mm aggregate;
- 16:1 for 1-2 mm aggregate.
