Staroxy 102 SF
Solventfree Epoxy Primer
Description
Staroxy 102 SF is a two-component amine cured solvent free epoxy coating. It is transparent. It ensures very good adhesion on most concrete floors in atmospheric environments only. Specially designed for high build floor coatings on properly prepared concrete floor substrates.
Uses
Designed for a wide range of floors with various levels of mechanical and chemical exposure. It is a primer for all Stanrose surface coating products. Specially designed for use with the traffic deck system for heavy duty traffic, areas such as ramps, car parks, parking bays, pedestrian walkways, roof decks and industrial floors. Recommended for cold stores, laboratories, hospitals, food and beverage plants, kitchens, high tech manufacturing facilities, dairies, warehouses, factories and hangars. This product when used with Stanrose Deck Guard (Antiskid) Aggregates, is suitable for filling and repairing of cracks, undulations and surface imperfections.

Directions for Use
Substrate Requirements:
• To secure lasting adhesion to the subsequent product all surfaces shall be clean, dry and free from any contamination. Substrates Temperatures must be a minimum of 55-60°F. and a maximum of 85°F.
• Laitance deposits are best removed by Planetary diamond disc grinder or by captive blasting followed by vacuum cleaning to remove dust debris.
• Substrate must be clean and free of Dirt, waxes, curing agents and any other foreign material that will interfere with bonding.
Surface preparation:
Remove oil, grease and any other contaminants using thinner. Blast clean to minimum Sa 2½ (Swedish standard SIS 05 5900). If blasting is not practically possible, make full use of mechanical tools to remove loose rust and scale to St.2 Swedish standard. Surface should be clean and dry before application of Staroxy 101 SB. New concrete or cementitious substrates should have been placed at least 28 days and have a moisture content of less than 5% before topping with Staroxy 102 SF.
After surface is dry, all repair work like sealing of joints, crack filling of cavities and crevices should be carried out.
If the surface is Tremix or smooth surface then Shot Blasting is carried out to make the surface rough in order to enhance the bonding of the primer.
Concrete defects such as voids, bug holes, excess porosity, and physical and chemical damage are usually filled or repaired prior to the installation of the F/C system. (Materials such as slurries, mortars, and polymer concrete are used to level, smooth and patch concrete surfaces.
The laitance (A thin, weak, brittle layer of cement and aggregate on concrete surface) on in-situ bases and any surface sealer or curing membrane should be entirely removed by suitable mechanized equipment, e.g. shot- blasting, panning or grinding, to expose cleanly the coarse aggregate
Mixing and Application:
1. Pack components are pre-weighed for optimum performance. Never split packs.
2. Stir resin thoroughly and then mix two parts of resin with one part of hardener by volume. Empty contents of Resin into a mixing container and pre-mix to assure the suspension of solids. Stir resin thoroughly and then mix two parts of resin with one part of hardener by volume.
3. Add Hardner and continue to mix to a uniform consistency for 1-2 minutes.
4. Mix with slow speed drill or manually depending on the quantity in mixing bucket and helical spinner head for 2 minutes.
5. Spread the mixture on the floor immediately and allow it to dry for 4 hours.
6. Primer is normally spread with a brush, floor squeegee or roller and back-rolled with a 3/8" medium nap roller. Care should be taken to minimize the entrapment of air caused by over rolling.
