Wanted Linseed oil UV catalyst recommendations

Postby Uvfastcure » Wed Jul 08, 2015 8:47 pm

Need some recommendations for a UV catalyst for Linseed oil. @405 nm would be great.

I read somewhere that manganese dioxide works.

do you have info on manganese dioxide as an UV catalyst? It helps peroxides. Benzoyl peroxide is catalyst that might work on linseed oil....but not an UV one.

I tried the carbon/ manganese dioxide from an alkaline battery on some linseed oil...no reaction even in the sunlight after 2 minutes. I mixed it and flowed it into a thin layer( to absorb O2) and really saw no change. I will leave it in the sunlight for hours to see if it sets up faster than days

I had tried manganese/carbon right from the battery. Possibly the other chemicals mixed in might have interfered with the RX, so I rinsed the manganese/carbon in water twice and then dried it out. Still no reaction in direct sunlight. My other 3D printing resins solidify easily in sunlight.

Does anyone have any other UV catalyst suggestions?
