PRODUCT DETAILS：

Type 802 lost wax casting photosensitive resin is a yellow casting material with 80% wax content, complete combustion, no ash, and low expansion. The printed wax model has clear details and excellent hardness, tougher than 801#.

It supports a variety of paraffin casting conditions and is compatible with high-quality gypsum to enhance the excellent effect of using gypsum outsourcing to cast jewelry.

From retailers and designers who produce custom jewellery to large-scale foundries, jewelers can use Dayoude brand cast resins to expand their business.The high precision and smooth surface finish of Dayoude casting series resin allows you to go directly from design to production.

Use：802 is suitable for gold and silver jewelry ，and more suitable for wax crowns, steel bracket wax molds and other models that require hardness in the dental industry.

Washing

Remove the custom tray from the build platform and soak in IPA(isopropanol) or ethanol(≥95%) to remove the extra resin. Use an ultrasonic cleaner if necessary. Please be aware that IPA and ethanol must NOT be placed directly in the tank of the ultrasonic cleaner.

Removing Supports

Manually snap off or use a flush cutter to snip away the support structure from the printed model. Using the flush cutter, cut the supports as close as possible to their attachment points on the model. Be careful not to nick the model itself, as this can cause pitting that may be difficult to remove during sanding.

Post-curing

For post-curing, the curing energy and curing time depends on the post-curing unit. For example, a good surface hardness can be achieved by 10 minutes of post-curing using a 36W (12WCCFL + 24W LED) UV curing box at 405nm or using Formlabs FormCure curing box at 405nm at 60°C for 15 minutes.
