Product Information
Composition
Chemical Base : Epoxy
Shelf life
12 months from date of production.
Storage conditions
Store properly in original unopened, sealed and undamaged packaging, in dry conditions at temperatures between +5°C and +40°C. Protect from direct sunshine.
Density
Mixed Density 1.68 kg/l at 30°C
Application Information
Product Temperature
Sika Hibond must be at a temperature of between +10°C and +40°C for application.
Ambient Air Temperature
+25°C min. / +40°C max.
Substrate Temperature
+25°C min. / +40°C max.
Pot Life
Temperature | Sika Hibond |
30°C | 4-5 hours |
The pot life begins when the resin and hardener are mixed. It is shorter at high temperatures and longer at low temperatures. The greater the quantity mixed, the shorter the pot life. To obtain longer workability at high temperatures, the mixed adhesive may be divided into portions. Another method is to chill parts A+B before mixing them (not below +5°C).
Open Time
| Temperature | Sika Hibond |
30°C | 7 hrs |
Consumption
1pack of 600g covers approximately 12-30 sqft depending on roughness and porosity of substrate
1pack of 1.2kg covers approximately 24-60 sqft depending on roughness and porosity of substrate (0.200- 0.500 kg/sqm depending on roughness and porosity of substrate)
Application steps
SUBSTRATE QUALITY
Mortar and concrete must be older than 28 days (dependent on environment and strength).
Verify the substrate strength (concrete, mortar).
The substrate surface (concrete, mortar) must be clean and free from frost standing water.
Concrete substrate must be sound and all loose particles must be removed.
SUBSTRATE PREPARATION
Concrete, mortar:
Substrates must be sound, dry, clean and free from laitance, ice, standing water, grease, oils, old surface treatments or coatings and all loosely adhering particles to achieve a laitance and contaminant free, open textured surface. Cement laitance must be removed and the surface to be treated must be mechanically roughened Steel:
Must be cleaned and prepared thoroughly to an acceptable quality i.e. by wire brushing, blast cleaning or vacuum.
MIXING
Part A : Part B = 2 : 1 (by weight) Pre-batched
Mixing Time
Pre-batched units
Mix parts A+B together for at least 3 minutes with the provided spatula until the material becomes smooth in consistency and a uniform grey color. Avoid aeration while mixing. Then, pour the whole mix into a clean container and stir again for approx. 1 more minute at low speed to keep air entrapment at a minimum. Mix only that quantity which can be used within its pot life.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with Sika Colma Cleaner immediately after use. Hardened / cured material can only be mechanically removed.
