SikaCor® VEC

Conductive vinylester resin mortar

SikaCor® VEC is a cold-curing 2-pack synthetic resin mortar made of SikaCor® VE Lösung (solution), SikaCor® VE Härter (hardener) and SikaCor® VEC Mehl (powder), an inert carbon filler.

Wide ranging chemical resistance to acids, leaches, solvents and notably to oxidising substances (e.g. chlorine bleach)
The cured mortar conducts electricity and thus can be used for the production of electrically conductive floors according to AGI-S30
Very fast curing

Usage

SikaCor® VEC is suitable for laying and jointing of bricks, tiles and special fabricated pieces made of ceramic or carbon for the production of chemical, thermal and mechanic resistant coatings and protective linings. Due to its extraordinary resistance against oxidising agents, SikaCor® VEC is used in the plants for stainless steel pickling, galvanising and for the production and processing of nitric acids.

Advantages

Wide ranging chemical resistance to acids, leaches, solvents and notably to oxidising substances (e.g. chlorine bleach)
The cured mortar conducts electricity and thus can be used for the production of electrically conductive floors according to AGI-S30
Very fast curing

Consumption

Coating system and consumption

Priming coat:

1.000 kg SikaCor® VE Lösung (solution) (100 parts)

0.015 kg SikaCor® VE Härter (hardener) (1.5 parts)

1.015 kg = 1 l final mixture

consumption: approx. 0,3 kg/m²

Bedding and jointing mortar:
0.450 kg SikaCor® VE Lösung (solution)    (100 parts)
0.007 kg SikaCor® VE Härter (hardener)     (1.5 parts)
0.810 kg SikaCor® VEC Mehl (powder)        (180 parts)
1.267 kg = 1 l final mixture

Application steps

SUBSTRATE PREPARATION

Concrete:
Prepare surface areas by abrasive blast-cleaning.
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 %. Surface tensile strength not be below 1.5 N/mm². Polluted or chemically contaminated surfaces require additional adequate cleaning methods.

If panels have to be laid in alkaline mortar or silicate mortar with open joints, make sure that the mortar is hardened and dried before applying SikaCor® VEC.

To acidify the joints is not necessary.

The edges of the panels have to be free from mortar and the joints must be cleaned.

SikaCor® VEQ can be applied directly on sealed layers, such as polyisobutylen foils. In this case, surfaces have to be impregnated (see primers). The priming coat has to be blinded as long it is fresh. After hardening of the primer coat you can use SikaCor® VEC-Mortar.

SURFACE PREPARATION

Steel:

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

Free from dirt, oil and grease.

MIXING

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.
