TARDIGRADE EPST 110

Descripción del producto

Tardigrade EPST **0

Two Component, Solvent Free, Epoxy Resin Based Primer

Description of Product
Tardigrade EPST **0, is a low viscosity, solvent free two-part epoxy resin based primer.

Fields of Application
• Internal and external substrates
• On concrete and cement based mineral surfaces
• Normal to strongly absorbent surfaces
• Primer for all Tardigrade Epoxy and polyurethane surfaces
• Binder for epoxy based levelling mortars and mortar screeds
• With aggregate, it can be used as cast and repair mortar on the surfaces that require repair.

Advantages
• Low viscosity
• Ultrahigh bond strength
• Solvent free
• Strengthens the structure by penetrating into capillary spaces in concrete surfaces
• Easy application

Tardigrade EPST **0 Technical Data

Preparation of Substrate
Concrete substrates must be sound and of sufficient compressive strength (minimum *5 N/mm²) with a minimum pull off strength of 2,5 N/mm². The residual moisture content of the substrate must not exceed 4%, the substrate temperature should remain a minimum of *8⁰C and the temperature of the substrate must be at least *3⁰C above the current dew point temperature.
The substrate must be clean, dry and free of all contaminants such as dirt, oil, grease, coatings and surface treatments, etc. Concrete substrates must be prepared mechanically using abrasive blast cleaning or scarifying equipment to remove cement laitance and achieve a profiled open textured surface.
If in doubt of the surface, apply a test area first. Do not apply on wet or frozen surfaces and surfaces with high humidity.

Application Conditions
During the application, ambient temperature should be between **0⁰C and **0⁰C. Relative Air Humidity should not exceed *0% and the substrate temperature should be between **0⁰C and **0⁰C. Substrate humidity should be maximum 4%. Substrate temperature shouldnt be less than *8⁰C and must be at least *3⁰C above the current dew point temperature.

Mixing
Make sure that the product temperatures are between **5⁰C and **5⁰C before starting the mixing procedure. Prior to mixing, stir part A and B separately with a mechanical drill and paddle at a very low speed.
Add component B gradually into component A and mix till you reach a homogeneous consistency (Approximately 3 minutes).
If it is going to be used as a repair mortar, please add aggregate after mixing A and B components. Pour the contents into a clean container and mix
for another couple minutes.
Please avoid mixing on high speed and do not add any solvent, etc. into the mixture during the application procedure.

Application Procedure
Avoid application under excessive heat or wind, rain and/or when the ambient and/or substrate temperature is below **0⁰C or above **0⁰C. In extremely cold conditions, heaters should be used to increase the ambient and the workability of the product.
After the mixing procedure, Tardigrade EPST **0 can be applied to the surface by using brush, roller, trowel or squeegee. Make sure that a continuous, pore free coat covers the substrate. Apply two coats if necessary. Aggregate (******0 micron thick) is transferred to the still wet primer in order to improve adhesion of the following epoxy or PU coat.
Mixed product should be applied in max. *0 minutes in about **0⁰C. of waiting time between coats should be minimum *0 hours in **0⁰C and maximum *8 hours. If waited more than *8 hours, the surface should be sanded.
The product would be completely cured in a minimum of 7 days to reach its maximum mechanical and chemical resistance.
Reaction times of resin based systems depend on ambient and substrate temperatures as well as relative humidity. Under lower temperatures reaction times are longer and this increases pot life, coating interval and working time. High temperatures increase chemical reactions and the above mentioned time decreases accordingly.
After application, the material should be protected from direct contact with water minimum for *4 hours. Within this period, contact with water can cause a surface carbonation and/or surface tackiness, both of which must be removed. In such cases overall coating should be removed from the floor and renewed.
Epoxy and polyurethane flooring systems, should be performed by expert contractors.

Cleaning of Tools
Clean all tools and application equipment with thinner immediately after use. Hardened/cured material can only be mechanically removed.
