Hi,
I am using a mix of 2 polymers and want to try and crosslink them. I have a UVA lamp of 365nm and have tried the lab previously at 30cm above. How would you recommend I approach the lab and what questions should I ask myself? I am looking at the excitation values for each polymer, but not exactly sure how long I should shine the UV light over the polymers for.
Thank you.
Omar
The uv lamp the penetration verry low just you must do it with very thin of polimer solution and with clear solution no pigmentation
Gatot Trimulyadi Rekso Thanks for the response. What about the distance and the time I radiate for? I am currently doing 2h, 3h, 4h and if I have time, going to go up to 10h.
In my experience distance around 10 - 20 cm, and how long depent on the reactivity of the polymer and photo inisiator used.
