silmar 249 OB 3

General Discussion

Hi,

need to buy  a new drum of resin next week. The last one I bought was a silmar 249BA. Like it. 

My dealer only has  silmar 249 OB 3 right now (wich I never hear about). That´s the code he gave me and he does not know the difference. (not a boardbuilder guy). 

I guess it has something to do with “optical Brightener”. 

Does anyone know something about it? Pros cons

I would not like to screw it. 

 

Thanks.

You got it right. There are various optical brighteners to the resin which is indicated by the number. It’s really a personal preference. If anything, see if he can pour out a bit so you can check it out first hand.
