Photoinitiator and Photopolymerization

Hi,
I've been making some research about cheaper UV Resine, since I live in Brazil and it's too expensive to import, and found an article about mixture of resines and photoinitiators.
It's in portugues but in page 10 and 11 there is a table with the chemical name and comercial name of photoinitiators. The article is about the importance of photoinitiators in uv curing paint, but since paint is made with polymers i'm going to try to mix with polyester and epoxi resin.

Batuta,

Looking forward to your test results.

the resin is coming this week i think. I bought it with a "uv absorber" and a catalyst. Trying to find more photoinitiators suppliers.
Already found that "A velocidade de cura pode aumentar em 20% nos substratos brancos comparados aos pretos. Os substratos transparentes e refletivos podem favorecer a velocidade de cura em proximadamente 40%."
That is "curing speed can increase 20% in white resin compared to dark ones. Cristal clear resins may increase speed curing in 40%"

Had some good results with polyester resin+DMA+10W Led. But just got an email of a resseler of [igmresins.com]. They'll make me a formulation for my project . Will make more tests later, waiting products to arrive.
Ps.:much better than US$200,00 kg, try to find some chemical labs ins your area!

Good to hear that a LED is working.
What is DMA?

Post a picture or video of your results, even if it's a blob.
Tks.

Hi Batuta,

I have sent quite a lot to Brazil, the shipping is not expensive and at moderate quantities, there are no import duties.

Hi Batuta,

I'm from Vietnam and now i'm interested in formulation an uv curing resin for my purpose. Could you please let me know the reference fees for your formulation from igmresin.

Thanks
