KRISTAL 100 Processing recommendations
- Materials should be stored and used at an ambient room temperature of 23°C with relative humidity below 85%.
- Warmer temperatures will reduce pot life and may also influence the casting thickness.
- If ambient room temperature is warmer than 25°C, reduce maximum casting thickness by 50% or as appropriately required to avoid excessive exothermic reactions.
- Due to the higher viscosity of Kristal 50, it is recommended to pre-warm resin and hardener to 28°C – 30°C prior casting to minimise air bubble entrapment, then leave to cure at 18°C – 23°C.
- Kristal resin systems can also be vacuum de-aired to minimise air bubble entrapment.
KRISTAL 100 Safety and handling
Epoxy resins and hardeners are chemicals and the below safety precautions should be practiced when using these materials.
- Work in an environment with adequate ventilation and avoid breathing fumes (a NIOSH approved respirator is recommended)
- Use protective Nitrile gloves to avoid skin contact
- Barrier creams can also be used to minimise skin contact
- If accidental skin contact occurs, use soap and water or hand cleaner to wash hands (never use solvents)
- Measure out part A – resin and part B hardener as indicated using an accurate digital gram scale
- Mix resin and hardener together thoroughly for 3 – 5 minutes using a flat paddle mixer, also scraping the sides and bottom of the container several times. Pour mixed material into a clean container and mix for another 60 seconds before casting. (this is a “mix pour mix” technique that ensures that part A & B on the sides and bottom of the container are properly blended so that there are no tacky spots or streaking in the cured casting)
- Allow adequate time to fully cure before sanding, polishing, and using.
- Wear appropriate safety gear and dust mask when sanding and polishing cured resin
