Oil-like-stains,frost stain on harden resin surface, where do they come from? How to fix it?
Some people working with epoxy resin You will definitely encounter this problem, the cloudy frost stains like oil stain and blemishes and it’s floating on your finished resin project’s surface!! This stain is caused by relative humidity in the air, It’s often happen when making resin projects on rainy day! So avoid to working resin project in humid weather or an air-conditioned room. (strongly recommend to work in a well-ventilated place, to avoid harmful by gas from resin) But ,sometimes you have to work on a rainy day
Sometimes I have to work on a rainy day. Let's see the next method.
Watch me remove frost stain on my resin phone case , using melon resin (UV-led resin) :
1. fruits hot air dryer, heat gun
This method help to remove moisture from the resin when hardening also making them curing faster
How to use is to pour the resin for a while, about 2 hours, until the resin is sticky. Slowly put into the oven at 60 degrees Celsius for about 1-2 hours, depending on the thickness.
2. UV resin
for small resin projects like accessory, keychains, phone case, you can use a UV resin to getting a shiny glossy finished and no frost stain anymore! ( UV resin can harden within minutes by UV lights, so humidity is not a point. Before you fix that surface, rub the surface and wash with water and then pour UV resin on the surface you want.
