SILIKAL® RV 368 resin is characterized by outstanding impact resistance. Its high elasticity ensures lasting crack bridging, so that substrate movements can be better absorbed. The good low-temperature fl exibility improves its behavior outdoors in the event of changes in climate or load stresses on bridge roadways or in cold stores. Because of the high viscosity, the coarse particles of the fi ller remains longer in the self-leveling recipe suspension, so that no separation between fi ne and coarse particles occurs within the fl ooring (particle homogeneity). This has a further benefi cial effect on crack bridging. When combined with fi ne fi ller, SILIKAL® RV 368 resin can also be used as a 1 – 1.5 mm membrane underneath normal fl ooring systems of SILIKAL® R 61, SILIKAL® R 62 or SILIKAL® RV 368 resin in order to improve impact resistance and crack bridging (tight to liquids).
Applications & Uses
- Applications
- Application
SILIKAL® RV 368 resin is used as a binder in manufacturing various coating types and recipes. Indoors it can be coated on the following substrates: concrete, screed, ceramic tiles, asphalt and steel. Outdoors SILIKAL® RV 368 resin, like all other SILIKAL® resins, must not be laid on asphalt surfaces because otherwise cracks may be expected to form, particularly on large surfaces. The various substrates must be primed in accordance with our general recommendations (see literature on substrates).
Membrane Coat: SILIKAL® RV 368 resin must always be applied to a minimum thickness of 1 mm. Mixtures in a ratio of 2:1 to 3:1 with SILIKAL® Filler QM have proven to be most suitable. Membrane coats must not be sanded over their full area before being covered with SILIKAL® R 61, SILIKAL® R 62 or SILIKAL® RV 368 resin self-leveling coatings. Membrane coats are advisable e. g. on blasted sheet steel, critical substrates or if there are particular mechanical stresses.
Main Coat: For the main coat, a differentiation must be made between two fi ller recipes. The fi ner is used in the manufacture of thinner toppings of 2 - 4 mm, the coarser for thicker coats of 4 – 7 mm. The recommended sand sprinkling of SILIKAL® Filler QS 0.7 – 1.2 mm is absolutely essential, as this ensures the surface straining point stress. Dried basalt chippings or coarse quartz sand is also suitable for sprinkling over areas subject to traffic.
