Please read the instructions carefully before use and master the test technique and technique. 3. Do not touch skin directly when using. Wear protective gloves. 4.When you stick it, the surface must be clean and dry. 5. UV resin hardening must be completed under UV rays. Use special UV light. 6. Do not touch with your hands immediately after UV irradiation. Touch after curing or cooling to avoid burns and marks. You may be concerned about the following: 1. Recommended UV light: more than 6w, higher wattage, the shorter the cure time. Wavelength: 365-400nm 2. Curing time: under experiment, 3-5 minutes under 36W UV light, extend the time according to the actual thickness. 3.How to remove air bubbles 1. Heat the bottle before using. 2. Flip the bottle for a few minutes before use. ③Pour slowly near craft 4. Leave it for a few minutes before irradiation. 5. Pick up bubbles with a toothpick or silicone stick. 6. Heat the UV resin with a heat gun or heat mat. 4.Why hard to hard? ①UV resin is not suitable for large, deep or opaque molds. UV resin is not desirable, if you want to make something more than 8cm, such as coasters and trays. Epoxy resin is sure to be effective. 2. Ensure sufficient illumination time. 3. Do not put the UV resin too much once. Review: Love this brand of Resin! Review: Yup. Love this resin. Cures hard, fast, not tacky, nice and clear. Everything you want.
