R-Cast 2.0 is designed for mass casting like river tables, charcuterie boards and any other artistic project. RC2 can be used for pours greater than 1/2″ (1.3cm) and up to 2.5″ (5cm) taking volume into account.
The use of fans is strongly recommended for thick castings.
Restrictions
Preparation
Mold
1- Use a plywood or melamine sheet and cover it with red or blue Tuck tape.
2- Assemble side and seal corners with silicone to make it 100% leakproof. Clean the excess and let it dry before pouring.
Wood preparation
3- Remove bark and clean any residues to ensure a perfect bond between wood and epoxy. Wood moisture MUST BE under 12% (Kiln dry).
4- For clear pours, we recommend to seal the edges with a thin coat of R-Epoxy (let it dry 24hrs and lightly sand for a perfect bond).
5- Assemble wood pieces as desired in prepared mold. Use clamps to hold the pieces in the bottom of the mold. Keep in mind that wood floats!
Epoxy preparation
6- Mix the required amount of epoxy for at least 5 minutes. Mix counter clockwise to minimize bubbles.
7- If necessary, add pigment and mix for another 3 minutes.
8- Pour your mix in your mold.
9- Room temperature must be 21°C ( 70 F). To avoid exothermic reaction, use cooling fan for the first 24h.
10- Unmold project when the epoxy is hard to touch (approximately 4 to 5 days).
11- Flatten the surface with router or CNC.
LOVE everything I've ordered! It's all great quality, nice and flat, great selection and perfect for laser projects. Highly recommend KJP! Please continue to carry Houston Acrylics as well- love their acrylic colours and supporting their small business as well. The pattern ply are fun and so nice too. Thanks KJP! This Canadian laser user is so happy to have found your shop.
I have ordered the craft 1/8" walnut plywood from KJP with great results, but this 'TruFlat' stuff is not real walnut. In any case, looks very different from the other laserable walnut mdf-veneered product I have from Trotec, as well as the other craft ply walnut from KJP- which is good for lasering, btw. Order a sample first. It is very flat tho, but lookswise its not what we were looking for... not going to get this again.
