Alkadur EPL
Base:
Material Group:
Epoxy resin
Membranes; tank- / vessel-linings - laminates
Laminate system for concrete and steel substrates
Description:
Chemical Resistance:
Alkadur EPL is a laminate system based on a special
epoxy resin for the creation of chemical resistant and liquid-tight linings on concrete and steel substrates. To improve chemical resistance the system can be covered by
tiles or bricks.
For detailed information please refer to Technical Information 230 E. Please contact our application engineering
for approval of the project-specific possible application.
Substrate:
Use:
Creation of chemical resistant and liquid-tight linings for
tanks, vessels, columns, reactors, towers etc. also
against thermal load. Creation of chemical resistant protection layers under tile or brick linings for tanks, vessels,
columns, reactors, towers, channels, foundations and
floor areas.
Concrete / screed
Refer to DIN EN 14879-1 as well as to STEULER-KCHFormsheet 010.
To attain a sufficient adhesive tensile strength, the substrate is generally to be pretreated in such a way that it is
free of cement slurry, cement skin, loose and crumbly
particles, structure imperfections and separating substances.
Properties:


chemically highly resistant
thermal resistance (load at the surface of the laminate):
up to 80 °C as membrane on concrete substrates;
up to 100 °C on steel substrates depending on
chemical load;
up to 120 °C as membrane under tile or brick linings

Steel:
Refer to DIN EN14879-1 as well as to STEULER-KCHFormsheet 020.
The steel surface shall be sandblasted to a metallic bright
finish. A preparation degree of Sa 2 ½ acc. to DIN EN
ISO 12944-4 and a roughness grade “medium (G)” acc.
to DIN EN ISO 8503-1 must be achieved; minimum surface roughness Rz = 70 µm. After blasting, a new formation of rust is to be avoided by appropriate procedures,
e. g. immediate application of a primer.
The substrate should have a temperature of
approx. 12 – 25 °C.

Residual moisture content of concrete substrate must not
exceed 4 %. During application, the substrate must be
kept absolutely dry. Uncured material has to be protected
from any kind of moisture (condensation, fog, precipitation or other water source). Distance to dew point has to
be at least 3 K, at a relative humidity of above 70 % at
least 5 K.

Safety Measures
Mix and apply material only in well ventilated areas. Provide
ventilation suited to the conditions when working in pits or
tanks. Do not smoke!
Do not expose materials to heat or open flame. This applies
in particular to welding works (weld beads). Avoid direct contact of the material with the skin. Wash hands with soap and
water; do not clean the skin with solvents. Use barrier soap
and protective creams on exposed skin areas. In all other respects comply with the relevant regulations for prevention of
accidents.
Refer to the Safety Data Sheets!
