SikaCor® VEL

• Satisfies the requirements of the ‘principles of Construction and Inspection for the Protection of Waters‘ (Bau- und Prüfgrundsätze für den Gewässerschutz) of the DIBt (Deutsches Institut für Bautechnik - German Institute of Building Technology) and is building inspectorate approved for concrete

• Coating based on vinylester for concrete protection according to EN 1504, DoP, with CE-mark.

In originally sealed containers in a cool and dry environment
(at max. + 20°C).

Up to max. 0.2 mm

According to the approval of the DIBt (German Institute of Building Technology), approval number Z-59.12-69 for test groups 1, 1a, 2, 3, 3a, 3b, 4, 4a, 4b, 4c, 5, 5a, 5b, 6, 6b, 7, 7a, 7b, 8, 9, 9a, 10, 11, 12, 13, 14, 15 and 15a
 

Additional building inspectorate approval for the following materials:
- hydrochloric acid ≤ 37 %
- sulfuric acid ≤ 70 %
- nitric acid ≤ 65 %
- aqueos sodium hypochlorite (12 % active chlorine)
- hydrogen peroxid ≤ 30 %
- chromic acid ≤ 50 %
 

Note:
In particular cases a discoloration of media may occur.

Nevertheless this does not effect the chemical resistance itself.

Dry heat up to approx. + 100°C
Damp heat depending on chemical exposure upon request

≤ 1 x 10⁸

~3 mm

Min. + 5°C, max. + 30°C

Max. 80 % (temperature ≥ 3 K above the dew point)

Provide good and sufficient ventilation during application!

Water, even in minimal quantities, may damage the accelerating system and avoid the hardening process of the mortar.

Please keep tools and mixers absolutely dry.

Concrete:
Cleaning of the surface by shot-blasting, pressure blasting or milling (after milling shot-blasting is necessary). The surface must be dry, firm, fine gripping, free from loose and friable particles, mortar laitance, dust and other contaminations. Residual moisture content not above 4 % acc. to CM. The average value of surface tensile strength should not be below 1.5 N/mm². When working on very dirty or highly chemically contaminated surfaces, additional adequate cleaning methods are necessary. Structures that are subject to the provisions of water resources law (Wasserhaushaltsgesetz - WHG) may only be coated by qualified coating firms possessing certificates of capability.

Steel:

Blast cleaning to Sa 2 ½ according to ISO 12944-4.

Free from dirt, oil and grease.

Fill SikaCor® VE Lösung (solution) in a container and add SikaCor® VE Härter (hardener) at the specified mixing ratio. Stir thoroughly until a homogeneous compound is obtained. Then fill into a clean container to stir up again. Add powder according application and required mixing ratio. Mixing time should be at least 3 minutes.

Troweling, laminating, rolling = undiluted

Primary screeding:
SikaCor® VEL primary screeding should be applied with smoothing trowel.

Laminate:
SikaCor® VEL binding material is first rolled onto the hardened SikaCor® VEL Primery screeding with a pile-fabric roller. Glass fibre matting (Vetrotex M 113 or Advantex M 113) with a mass per unit area of 450 g/m² is then immediately laid on, pressed in with the roller and simultaneously saturated with SikaCor® VEL binding material.

A 2_nd layer of the same glass fibre matting is laid on top of the 1_st layer, thoroughly soaked, matting layer, pressed down in the same way with the roller, and saturated with SikaCor® VEL binding material.

Finally the 2_nd layer of glass fibre matting is covered by a layer of surface matting (approx. 30 g/m²) pressed in with a laminating roller and rolled out ensuring that any air that has become included is completely expelled.

Top coat:
In order to discharge static electricity, conductive tapes / braids are glued on to the SikaCor® laminating layer, joined to the equipotential connection, and covered with the top coat SikaCor® VE Lösung leitfähig (solution conductive). Repeat application after 3 - 5 hours after curing of the first top coat.

Alternatively to the conductive top coat you can apply SikaCor® VE Lösung RAL 7032 (solution RAL 7032) as non-conductive top coat.
 

Non slip characters:

To improve the non-slip characteristic the 2_nd coating may be broadcasted with carbon silicide (0.5 mm). Needed quantity is about 0.5 kg/m².
