Medium Casting Epoxy Resin

Manufacturer's Brand Name: Kristal 30
 

Overview

  • For casting in layers between 5mm and 20mm thick (maximum cast volume is 10 Litres). It can be cast in layers up to 30mm thick if the ambient temperature during curing is around 18oC or below. 
  • Clear, UV Stabilised (slow to yellow compared to non-stabilised resin but clear resin will eventually start to discolour outdoors).
  • FDA approved for food contact up to 50oC. (Test method: FDA 21 CFR 177.2600 report number GZ190826027FR)
  • Low viscosity (high flow resin) so air entrainment is less of a problem than with higher viscosity systems.
  • The cured resin is suitable for heat contact or exposure up to 80oC..
  • The cured resins is glossy, strong and very hard (Shore D Hardness: 85).
Mixing ratio is 100 Resin : 33 Hardener by weight. This resin should not be measured by volume.
 

Typical applications of this epoxy resin

  • Casting in moulds and river tables in layers between 5mm and 30mm thick.

Many of our silicone moulds are about 5mm deep so this resin can be used in many all the moulds that we sell. At 5mm thickness it cures slower than our Counter Top & Shallow Casting Resin but it has the advantage of placing less wear and tear on the moulds as it is not quite as hard. If you have patients and don't mind the longer curing time (especially in winter) then this will be the resin to extend the life of your silicone moulds.

General points for all resin work

Resins are not simple to work with and you should not attempt resin art if you are not prepared to experience a learning curve. Start small and get to know your products and the correct methods.
Preparation and mixing are crucial for any resin project to be successful. Read and follow all instructions carefully. Only mix the quantity that you will use immediately as resins cannot be stored after mixing. The heat generated in a container of un-poured resin or in resin that is applied too thick can reach dangerously high levels.  The maximum layer thickness indicated does not apply in all conditions and must be reduced in hot weather and when casting into closed systems with little surface area for heat loss. 
 
You need to take health precautions when working with resins so read safety and health instructions carefully. The hardener of epoxy resins is an irritant to the eyes, skin and mucous membranes. Avoid direct skin contact an never get it in your eyes. Wear safety glasses, long sleeves and rubber gloves to minimise skin contact. While good quality epoxy resins are VOC free and don't give off significant fumes at ambient temperature, they can give off off fumes if they get hot during curing and many additives such as colourants do give off fumes. As a minimum always use resins in a well ventilated area and don't let them cure in your bedroom for example. If you work with them regularly or on large projects then wear a suitable respirator.
Keep out of reach of children.

How to calculate the amount of resin required:

 
You must use a scale and resin mass. You cannot measure this resin by volume.
 
For a roughly rectangular shape multiply as follows:
Resin required in kg = Surface length in m  x  Surface width in m  x  required resin film thickness in mm x 1.1
 
For a roughly circular shape multiply as follows:
Resin required in kg = 3.14  x  Circle radius in m  x  Circle radius in m  x  required resin film thickness in mm x 1.1
 
Example
If your rectangular surface is 1.2m x 60cm and you require a film thickness of 16mm
Resin required in kg = 1.2m * 0.60m * 16mm * 1.1    = 12.67kg of resin
 
Now work out how much of Part A and how much of Part B you need to give you the total requirement of 12.67kg
Ratio for this resin is 100A to 33B PBW (PBW = parts by weight).
 
To get 12.67kg total resin:
kg Part A required = 12.67/133 * 100 = 9.53kg 
kg Part B required = 12.97/133 * 33 = 3.14kg
