Colour:
transparent
Storage:
The product can be stored at least 24 months in its original unopened packaging, if kept dry.
Fields of application
weber.tec 793 is used as bonding layer for reaction resin mortars. Also as binder for reactive resin mortars mixed with silica sand for thick applications on horizontal concrete surfaces and screeds. Also as glue for several materials. For use indoors and outdoors.
Main features
- EMICODE EC 1PLUS: low emission of volatile substances
- 100% solids content (i.e no water and no solvent) as epoxy composition according to the test method of German Association for Construction Chemicals
- high compressive, flexural and bonding strengths
- excellent adhesion to concrete and screeds
- resistant to numerous diluted acids and alkalis
- resistant to animal and vegetable oils and fats
- for use indoors and outdoors
General notes
- All characteristics mentioned in this data sheet are given for a temperature of +23 °C, without draught and a relative humidity rate of 50%.
- Higher temperatures and lower humidity rates accelerate, lower temperatures and higher humidity rates delay the reaction process.
- Larger packaging sizes and higher temperatures shorten the pot life.
- As a rule, reactive resins require a compressive strength ≥ 30 N/mm2 and a tensile strength (pull-off strength) of concrete surfaces ≥1.5 N/mm2.
- The residual moisture content of the concrete must not exceed 4 CM-% (by weight); the moisture content must be measured with a carbide hygrometer (CM) as a rule.
- The substrate temperature must be at least 3°C above the prevailing dew point temperature to avoid risk of condensation.
- Reactive resins are gas- and watertight coatings; therefore, detachments due to water vapour pressure and/or frost-thaw damage cannot be completely excluded.
- Do not process when it is raining or threatening to rain.
- Do not add foreign substances during mixing and application.
