 1. What type of resin is best for doming?

Three types of resin are used in doming: Two part epoxy resin, One part UVcurable polyurethane resin, and Two-part polyurethane resin.

Two part epoxy resin Epoxy is easy to mix, and available to apply it by hand. However, it is very slow to cure, taking several hours, even when heated, this makes volume production of domes very difficult.  It is relatively cost effect than other two resins.  It is widely used for promotional items, such as key chain, magnets, name badges... etc. which are not likely to be exposed to outdoor (UV) light. This is very important, as epoxy yellows very quickly when exposed to light, so it will be only suitable for indoor products.

One part UV-curable  resin. Needs no mixing, and cures in a matter of seconds! The perfect material for doming? It is not exactly the right answer.  It is very expensive.  Its high shrinkage limits its application only available on low profile and small size doming.

Two-part polyurethane resin.  It is high  quality of surface finish, resistance to yellowing or deterioration, and its overall durability. Surprisingly, even with all these essential advantages.

2. How is the resin packaged?

Our standard package is 5kgs in plastic cans.

3. Why do I need Vacuum Degassing and Bubble Removal?

When it is cured polyurethane is extremely durable and resilient, however liquid Polyurethane is easily damaged by moisture. All air carries moisture, and therefore the quick removal of air bubbles from the liquid polyurethane is essential. No bubbles also means no time lost in getting back into production, for example, after changing to a new drum of material. By reducing the air pressure in the space between the top of the liquid and the underside of the drum a situation is created where the air pressure inside any bubbles is greater that that of the surrounding atmosphere. This causes the bubbles to rush to the top of the drum in much the same way that the bubbles rush to the top of a can of beer when it is opened. The bubbles, and the moisture-laden air they contain, are then removed by the vacuum system
