Q. What is the life of PRP if left in the can and if left in the can in a fridge?
A. Hi, thank you for your question. The manufacturer states that 'PRP has a shelf life of 12 months and should be stored above 4degC and below 30degC. As the lower temperature is only 4degC, storage in a fridge may not be advisable.

I brought this photoresist after reading another review. I have found that it dries very quickly compared to others and as long as the substrate is prepared correctly the results are very good quality. I am impressed how well this product works and would definitely recommend it over other photoresists.

I have to say that I am more than satisfied with this product. Price is the same as positive 20 £5 per 100ml. But what is much better is the application and curing. Application is straight forward and green color against red copper is contrast which I can not say about reddish color of positiv20. Drying is fast - hair dryer circa 50°C 15 to 20 minutes and you can apply artwork on the surface. On the other hand positiv 20requires at least 30 minutes at 80°C And my experience is that the surface is sticky for couple of hours. Resolution of this product is as well much better than this of positiv 20. I can recommend use of PHOTO RESIST 87-0726
