Syntech Primer EP-W: Bezrozpusťadlový dvousložkový epoxidový základ pro cementové povrchy
Syntech Primer EP-W
Syntech Primer EP-W is a solvent-free two-component epoxy resin to be used as a bonding primer for applying all epoxy cycles on concrete surfaces and concrete conglomerates in general. Syntech Primer EP-W is formulated to achieve an elevated impregnation, consolidation and adhesion effect of the substrate. It can also be used on wet surfaces. Syntech Primer EP-W even penetrates deep into compact surfaces, effectively consolidating the support. It also has a great resistance to water and aggressive solutions whilst allowing water vapour to pass through.
Promotes adhesion for epoxy coatings as well as for porous and deteriorated substrates, along with acting as a cement and concrete consolidation agent.
The support on which the epoxy, polyurethane or methacrylic system is to be laid must be suitable for withstanding the stresses resulting from the intended use, such as static or dynamic loads, impacts, thermo-hygrometric expansion, vibrations etc. As regards the characteristics of the substrate (maximum humidity, cohesion, strength class, flatness, etc.) and the preparation of the surface that will accommodate the resin system, we recommend the requirements set out in chapter 5 of the UNI 10966 standard ("RESIN SYSTEMS FOR SURFACES HORIZONTAL AND VERTICAL - INSTRUCTIONS FOR DESIGN AND APPLICATION "). In any case, carefully clean and degrease the surfaces, removing any kind of dirt, paint residues or incoherent parts. The humidity of the support must be <= 4%. Evaluate the most convenient type of mechanical preparation (shot peening, sandblasting, hydro-washing, etc.). The surfaces must also be free from discontinuity, and possibly leveled and regularized with products from the FLOOR line or the REPAR line or grouted with Syntech AS 21. In the event of the presence (even suspected) of humidity deriving from capillary rising from the substrate, it is recommended to apply the Syntech Pavidamp epoxy resin for "wet bottoms" beforehand. Tiled floors, or floors covered with pre-existing resin, must be subjected to mechanical roughening carried out with shot blasting, milling, bush hammering, etc., until the total elimination of the waterproof crust and the opacification of the surfaces. Remove dust after abrasion.
Mix the two components, each in its own container, before combining. Pour component B into component A and mix for 3 to 5 minutes with a low-speed mixing drill to achieve the complete homogenisation of the mixture. The protective coating can be applied once the Syntech Primer EP-W is completely dry.
Use 150 to 200 grams per square metre per coat, depending on the porosity and unevenness of the support.
