Polyester resins
The SILMAR polyester resins are used in close to 90% of the workshops.

- The "new" SIL249-BLH is quite efficient when used together with a traditional PMEK catalyst, for lamination of not-coloured boards. The optical colourant will give to your boards a ''whiter'' white.
- We recommend the SIL249- A "traditional" resin if you use it with together with pigments (tinted resin), or if you decide to work with a UV catalyst.
Whatever you decide, SILMAR recommends to work with their resins above 17°C, and to use 1 to 1,5% catalyst for a standard lamination (polymerization time: 10 to 15 minutes). For hot-coating, catalyst proportion should be increased to 2% (+ add approx. 4% of paraffined styren!). The dosage with a UV catalyst should be the following: 1gr of UV catalyst for 1 liter of resin. This will allow enough time to laminate/coat the the board, or to dry up some repairs in a record time.
Note: polyester resin is completely incompatible with polystyren resin, or you will face a melting reaction.
