Craft Resin's epoxy resin will bond well to every medium, with the exception of wax paper and plastics including silicone (i.e. materials that repel water).
It works extremely well on wood, photographs, inkjet prints, acrylic, oil paint that has completely dried, watercolour, spray paint, encaustic, ink, paper collage, oil pastel, sculpture, flowers, rocks, and other found objects.
You may want to avoid pouring it over loose materials (this may include chalk pastels); anything that is not completely adhered to the surface of your work could potentially mix into the resin in its liquid form once it's poured and float around. Some lower quality papers absorb resin rather than allowing it to sit on top, in which case a sealant should be used over the paper first to avoid seepage.
What materials will Craft Resin not stick to?
Craft Resin epoxy resin does not adhere well to disposable plastic paint tarps, plastic sandwich/grocery bags, silicone molds, and the non-sticky side of shiny tape. Artists can use these properties to their advantage when creating their pieces (e.g. jewelry made from resin poured in silicone molds).
Can I use Craft Resin over natural objects?
Yes, Craft Resin looks wonderful on natural objects such as wood, flowers, leaves, feathers, butterfly wings, and rocks to protect them and preserve their brilliant natural colours.
Some natural objects can off gas trapped air into the resin which can be prevented by sealing first. Resin can make natural objects look like they would when wet, so we always recommend testing first so you know exactly what to expect.
Some important points:
Craft Resin will make the colours look darker, as they would when wet - if you want to test this out how they'll look, use a little water over top to see how the colours change ( usually it's for the better! ).
Some natural objects need to be sealed - Some organic material, such as wood, can contain trapped air which can de-gas into the Craft Resin in the form of bubbles as it's curing. To prevent this, use a sealant over the surface first to create a barrier to prevent air from escaping.
Make sure natural objects are dry - Whether you resin over natural objects, it's important to make sure they're thoroughly dry first. Moisture causes wood to expand and contract which could cause the resin to crack. When it comes to leaves and flowers, you want to make sure these are completely dry, or else they may rot under the resin.
TIP: Place leaves and flowers in silica gel for to completely dry them out.Use caution when pouring and spreading over delicate areas of your artwork - Be aware that resin is thick and can be heavy if a large amount is used over delicate objects such as butterfly wings. Because of this, you may wish to apply the resin in thin coats.
As always, we always suggest testing on a non-masterpiece first just to make sure you get the results you want before you move on to your final project!
What is Craft Resin's heat resistance?
The maximum temperature that cured Craft Resin can tolerate after 21 days of curing is 200F or 93C.
At temperatures as high as that, the cured pieces may become a little flexible but once they cool off, they will harden up once again. Typically, the heat generated from a hot mug will not damage the resin surface on a coaster.
TIP: No matter which colorant you choose, do not exceed 6% colorant to the total volume of Craft Resin as this will affect the delicate balance needed for the chemical reaction to occur properly and guaranteed heat resistance.
Is Craft Resin food safe?
Yes, once Craft Resin is cured, it is fully inert and can be safely used as a food contact surface. Craft Resin has been tested by a third party for leaching and migration across worldwide standards and passed every test: when used as directed, cured Craft Resin will not leach any substances into food that comes into contact with it.
