TIPS TO HELP PRODUCE A PERFECT DEEP POUR EPOXY RIVER TABLE! 1. MIX RATIO
Mix at the correct mix ratio. Use an Accurate Scales to do this. Scales are available at AMT Composites
Please read the datasheet carefully to get the correct mix ratio. We strongly recommend you mix by weight as it is the most accurate method.
Mix the two parts together very well. Stir with a flat paddle stick for a minimum of 3 minutes, scraping resin from the sides and bottom of the containers into the mix. Then transfer the mix to another container, mix again and then pour.
3. DEPTH PER POUR
Choose the appropriate system to match the depth you require. The chemical reaction that occurs, generates heat. Large volumes of resin can generate excessive heat, which can lead to an exothermic reaction, and cause the resin to discolour, crack and warp!
4. CALCULATING HOW MUCH TO USE
To calculate the volume of resin required, measure the length, breadth and depth and convert to liters.
a. A table 2met x 900mm x 50mm deep is:
200cm x 90cm x 5cm = 90000cm3 90000/1000 = 90Lts.
The Specific gravity of the material is 1.1.
So 90Lts x 1.1 = 99Kg is total amount of Resin and Hardener required.
b. To calculate the separate amount of resin and hardener required, divide the total Kilograms by the mix ratio (ie 1.33 for the 100:33 mix ratio system or 1.25 for the 100:25 mix ratio system) and that will give you the amount of resin required
99/1.33 = 74.44Kg Resin (Mix Ratio is 100:33) 74.44 x 33% = 24.56Kg Hardener
Total weight = 99Kg Mixed Total
c. For tables with wood and live edges it is sometimes difficult to calculate the exact amount of resin required because of the irregular shape of the wood.
To do this see the example illustrated below:
Length x Average Breadth x Height
Average breadth is the sum of the measurement divided by number of stations
e.g. 10,5cm + 13.6cm + 11,4cm + 19,4cm + 20,2cm + 14,6cm + 11.8cm + 8,3cm = 109.8/8 = 16,3cm
* Manufacturer’s Brand Name: Kristal Diamond 6®
* Clear, UV Stabilised, Approved for Food Contact.
* The cured resin is glossy, ultra-hard (scratch resistant) and suitable for temperatures up to 80degC.
* A high flow resin for thin layers of 1mm to 5mm.
* Typical Applications: Bar counters and table tops, jewellery, shallow moulds, clear coating over art, coating over other resins to increase hardness and give food contact properties and thin layer resin art (e.g. art on glass, wood, tiles etc) where a thin (high flow) resin is required. Due to high flow nature of the resin sides may be required to get minimum 1mm thickness (do not use in layers less than 1mm thick).
Counter Top & Shallow Casting Epoxy Resin
Manufacturer’s Brand Name: Kristal Diamond 6
* Used in layers of 1mm to 5mm thick.
* 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 temperatures up to 80oC.
* The cured resins is glossy, strong and ultra-hard (Shore D Hardness: 90). It is very scratch resistant but not scratch proof.
Most of our silicone moulds are about 5mm deep so this resin can be used is almost all the moulds that we sell. At 5mm thickness the resin has the advantage of curing quickly. As it is an extremely hard resin it does place more wear and tear on the moulds than a slightly softer resin does. As our Medium Casting Resin can be used in layers of 5-20mm thickness it is also suitable for many of our silicone moulds. Our Medium Casting Resin will cure significantly slower in a 5mm layer but it will cause less wear and tear to the moulds than this resin will.
Mixing ratio is 100 Resin : 33 Hardener by weight. This resin should not be measured by volume.
Typical applications of this epoxy resin
* Bar Counters and Table Tops. A restriction is that this is a low viscosity (high flow) resin so if your surface does not have sides you will have significant losses off the edges.
* Kitchen Counter Tops. Restrictions are that despite being ultra-hard and scratch resistant the resin will be damaged by knife cuts and by hot items over 80oC.
* Thin layer resin art (e.g. art on glass, wood, tiles etc) where a thin (high flow) resin is required.*.
* Jewellery, Coasters and other shallow mould castings up to 5mm deep.
* Clear, glossy layer over art where a thin (high flow) resin is required.* Do not use over oil based paints or art with oily substances.
* Cast as a thin layer over other resins to increase the surface hardness and/or to create a surface suitable for food contact.
* Do not go below 1mm thickness as surface tension issues may be encountered. Surface tension defects can look like small craters or like the resin is ‘pulling apart’. This can happen on un-sealed wood even if you start with a resin layer greater than 1mm because resin will be absorbed into the wood resulting in a thinner layer on the surface. As this resin has a high flow it may flow off the edges of a surface before you get to 1mm thickness. Some retaining boarder or technique may be required to get a layer of 1mm. Always gain experience with each resin type before you use it on a critical application e.g. over an important painting.
General points for all resin work
Resins are not simple to work with. 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.
