– Characteristics After being fully cured, Sika Poxitar F will be tough – hard, very strong and highly resistant to abrasion and impact; Excellent resistance to water, bacteria and chemicals.
Sika Poxitar F may come into contact with water immediately after application, but be aware that solvent will spread in the water and cause temporary pollution.
Therefore, it is only necessary to immediately contact the product with water in special cases and after consulting with the environmental protection authority.
– Resistance
Effects of chemicals
Sika Poxitar F is resistant to clean water, seawater, oysters, acids and dilute alkaline solutions, neutral salts, inorganic oils and heat-generating oils, oily substances, detergents, etc.
Long-term resistance to benzene-hydrocarbons and tar oils.
Temperature
Dry heat up to + 100 degrees C; Moisture and hot water up to about + 60 degrees Celsius, if exposed for a short time can be up to a maximum of + 80 degrees C
No resistance to hot water in cases where the gradient is different
CONSTRUCTION
Prepare concrete surface
At least 14 days of age, solid, free from cement mortar, dust, and other flaky components and other contaminants.
Clean by blowing method to increase adhesion. This is especially important in the case of groundwater exposure.
Holes, large holes, etc., should be flattened with Sikagard 75 Epocem.
Steel
Cleaning by blowing SA ½ method according to ISO 12944, part 4
No dust, oil, grease etc.
Prepare the material The material has been packed according to the correct ratio. Stir component A (basic ingredient) thoroughly before application. Add component B (hardener) and mix well with an electric stirrer (move the stirring lever up and down).
When preparing in small quantities, keep the above mixing ratio.
Ready-mixed materials can be used immediately.
In the case of component B (hardener) crystallization, dissolve the product in warm water (+ 40 ° C to + 50 ° C) and allow the product to cool to normal temperature before mixing with component A (component). basic).
Application method Apply by brush: with brush, round brush or fan-shaped brush. Do not add solvents as they will delay the curing process, especially in the case of immersion.
Vacuum air spraying with airless equipment with a pressure of 150 bar, nozzle of 0.53-0.66 mm (26 thou.) Spray angle of 40o – 80o. At low temperatures, 5% Thinner S can be added, but in the case of immediate contact with water, do not add Thinner S.
Construction temperature The higher the ambient temperature and the surface temperature, the faster the curing will finish. Can be constructed at temperatures from +5 oC
Under unfavorable conditions, such as the effect of moisture on the new layer, the surface is damaged (turns brown) and has a surface that can be slightly rough like crocodile skin. However, this does not affect the functionality of the product.
Construction permit time About 1 ½ hours at a temperature of + 20OC
Waiting time between layers with thickness when dry up to 150 um Product Ambient temperature + 5oC + 10 oC +15 oC +20 oC +25 oC +30 oC
Standby time Minimum 36 hours 30 hours 24 hours 12 hours 8 hours 6 hours
Between classes Up to 96 hours 72 hours 60 hours 48 hours 36 hours 24 hours
 Waiting time between layers depends largely on temperature and weather.
If failure to comply with the waiting time as above can lead to adhesive problems, recovery will be required. The best method of restoration is to lightly sand, sand and then proceed to clean the dust before applying the next layer.
Last drying time If well ventilated, curing will end after about 8-10 days at + 20oC for longer maintenance
