What is the difference between epoxy resin and UV resin?
What is the difference between the epoxy resin and UV resin? Is resin hard or soft? Does UV resin degrade or not? Why is UV resin so expensive?
Epoxy Resin, also called UV reactive acrylic, is commonly used in industries such as automotive, marine, and construction. It is composed of a two-part resin-one part is generally a hardener while the other part is a catalyst that changes color when it comes into contact with light. There are some types of epoxy resins that have been reported to be toxic when ingested. This is the reason why epoxy resins are most commonly used in the preparation of paints and other similar products.
Epoxy Resin is generally hardened by adding binder, which makes it more durable and sturdy. There are a lot of advantages in using UV resin casting, which makes it more effective in mold making. Since UV resin can harden at different temperatures, it can be cast in molds based on itsmelization. In addition, UV resin casting can be used to create parts that are shaped or hardened at room temperature or below.
Hard or Soft Resin?
UV resin has the ability to harden or hardened using a variety of processes. In addition, it is possible to control the hardness of the UV resin by varying the cure time, curing time, or duration of exposure. It is for this reason that UV resin is popularly used for making parts and components that require strong adhesion, such as uPVC window frames and cabinets. Other types of UV resin that can harden include urethane and polyurethane. Although they can be cured at relatively low temperatures, they usually take longer to reach the intended hardness.
Hard uv resin has the ability to harden at very high temperatures. This means that if you need to create parts or components that are highly tough, then it is advisable to use hard uv resin. However, one of the most notable differences between hard uv resin is that UV resin can be cured directly in direct sunlight. Hard uv resin cannot be cured in indirect sun, since the curing process will lead to a rapid hardening of the material. The rapid hardening is possible because the curing time is shorter in the presence of direct sunlight.
UV Resin requires a slower curing time, which makes it ideal for use in molds that need to harden over a long period of time using low temperatures. If the molds being used are not particularly complex, then UV resin may be suitable for them. However, if the molds are complex, or if they contain lots of fine wrinkles, then epoxy resin may be the best option. Epoxy resin contains a UV protecting coating, which makes it much harder than UV resins. So when you are applying the material to a mold, it is important that you test how hard the material is first, before you add any other material to increase its hardness.
