What you will get: 100g Crystal Clear Hard Type UV Resin*2 User Manual*1 Pay Attention: 1. Store in a cool place. 2. Before use, please read the instructions carefully and try a little to master the trial skills and techniques. 3. Do not touch the skin directly and wear protective gloves when using. 4. The surface must be kept clean and dry when bonding. 5. UV resin curing needs to be completed under ultraviolet, please use special UV light. 6. Do not touch with your hand immediately after UV light irradiation, touch after curing and cooling, to avoid scalding and leaving traces. You may be concerned about: 1. The recommended UV light: 6w above, the higher the wattage shorter the curing time Wavelength: 365-400nm 2. Curing time: under the experiment, 3-5min under 36WUV light, and extend the time according to the actual thickness. 3. How to eliminate bubbles? ① Heat the bottle before use. ② Invert the bottle for a few minutes before using. ③ Slowly pour out, close to the crafts. ④ Let it sit for a few minutes before irradiation. ⑤ Pick out bubbles with a toothpick or silicone stick. ⑥ Heat UV resin with a heat gun or heating mat. 4. Why is difficult to cure? ①UV Resin is not suitable for large, deep, or opaque molds. If you want to make coasters, trays, or any other object larger than 8cm, UV resin is not what you want. Epoxy resin will certainly do better. ② Provide enough irradiation time. ③ Do not add too much UV resin at one time.
