  • 1. r Clear Epoxy Artwork Resin ~ This resin is an optically clear epoxy resin system formulated to produce clear laminates, coats, linings etc with good UV stability. ~ It is commonly used to seal/protect artwork, paintings, sculptures etc. ~ It is easy to use, cures at ambient temperature and is self-levelling. ~ The resin is non-flammable, odour-free and has no solvent content. MIXING RATIO: By volume 1 : 1 NOTE: The mixing ratio must be accurately followed. It is not possible to change the ratio. This would result in lower mechanical properties and the resin not drying properly. The mixture should be thoroughly stirred (mix for 3-4 mins) to ensure full homogeneity. Epoxy systems tend to heat up much faster in a pot than as a thin film. Therefore mix only the necessary amount usable within the given pot life. APPLICATION: The system can be applied by hand pouring or by brush/roller The resin can be tinted any colour with the addition of polymer pigments available in all solid and translucent colours. Mix in the ratio of 1:1 (by volume) until it is a uniform colour & consistency (usually 3-4 mins). Level: ensure your piece is perfectly flat and level, otherwise the resin will run to the lowest point and "pool" in the centre, leaving too little resin at the corners. On large canvas paintings/pictures you should tighten the canvas as much as possible or place a board underneath to support it uniformly. Bubbles: any bubbles created by hand-mixing can be easily popped by using a sharp object or by passing warm air over the surface of the resin (e.g using a blowtorch or hot air dryer on slow speed setting). Blowtorch: Don't hold the blowtorch or hot air blower closer than 30cm to your artwork otherwise you risk creating ripples and dimples in the resin finish. Oust: You will need to protect the piece from dust accumulation for at least 12-24hrs. You can do this by using a dust sheet or a box to cover the piece. Cleaning: All mixing containers and tools can be cleaned with Acetone or cellulose thinners. chemresinsPOLYMER RESIN SYSTEMS Liquid resins.solid solutions I 23D C (73°F) 25°C (77°F) Resin 6 500 - 6 800 mPa.s 5 500 - 5 600 mPa.s Hardener: 2 200 - 2 300 mPa.s 1 900 - 2 000 mPa.s Mixed Viscosity: 4 400 - 4 700 mPa.s 3 700 - 3 900 mPa.s I I ' Resin: Clear - Transparent Hardener Clear- Transparent ,. 23°C (73°F) Resin: 1.11-1.15g/cm3 Hardener: 0.94 - 0.96 g/cm3 , .
