We have a few different epoxy systems that are suitable for casting shapes, encapsulating treasures, or casting tables.
We have had very good experiences casting with our CCT epoxy with slow hardener and with Resin Research 2050 with extra slow hardener. For larger pours we recommend keeping the layer thickness to around 3/8" this can vary with the addition of objects such as rocks or other articles that will help absorb some of the heat produced during cure. We recommend following up with the next layer of resin soon after the previous returns to room temperature. Both resin systems are low viscosity for excellent release of bubbles and penetration into the substrate. They can be used in a bar top type application but their low viscosity means you will either need to dam around the edges to get a thicker coating or do multiple coats.
Entropy CCR with the slow hardener is also an excellent choice for casting deeper pours.
For bartop applications where you want a thick resin that will sit on top of the material being coated Mirror Coat is a good option for that. Under typical room temperatures it will coat out to about .040" thick in one pass. Mirror Coat products can be found here.
Please feel free to contact us with any questions about our products and using them to cast table tops or other articles.
Resin Research 2050 Low Viscosity Resin for RTM and closed molding processes.
Click on Item for pricing and sizing options, available in 1 gallon (9.1 lb) and 5 gallon (52 lb) kits.
Resin Research 2050 is a 3:1 clear epoxy resin system for closed molding processes such as vacuum infusion and RTM (resin transfer molding) It is available with three different hardener options to best match your needs:
3100F Fast Hardener has a Pot life of 20 minutes and Set time of 2.5 hours
3100S Slow Hardener has a Pot life of 50 minutes and Set time of 5 hours
3100X Extra Solw Hardener has a Pot life of 90 minutes and Set time of 10 hours
(quoted Pot life and Set time based on 77F temperature, results will vary based on actual conditions)
Contemporary Composite Technologies Epoxy System with Slow Hardener Features:
Clear Epoxy and Hardener - Great for projects and products that will have a clear finish. i.e. Carbon Panels, Surfboards, Wood Boats, Photos, Plaques, and Castings.
Low Blush System - Less work in between coats
Flexible Resin - Great for high impact parts or parts that will flex or move, such as wood substrates
Low Viscosity - Wets out fabrics quickly, bonds well to hard to bond surfaces including woods, metals, and concrete
UV Stable - Resists browning or yellowing
2:1 Mix Ratio - Easy mix ratio to calculate for both small and large batches
Slow Hardener has a 50 minute pot life at 77F.
Recommend working in temperatures above 65 F
While resin is UV stable it does not contain UV inhibitors to protect the substrate, using a clear paint or varnish topcoat for projects that will be exposed to direct sunlight on a consistent basis is recommended.
