Hey, this is first post so please realize I may not be used to the forum format.
I have one question. I am experienced with resin, accelerators, MEK and styrene use. Here in Thailand we get raw resin without any formulation so I have to add styrene monomer, cobalt accelerant and of course MEK.
Not having a wax based resin or gel coat available here has been a major problem for years. I want to add paraffin wax to styrene monomer and then add this surfacing agent to homemade polyester resin as a surface barrier to cure well.
I see you call this a surface coat and there were many posts already on this subject but I found them confusing mixing liters with grams. I will make my question precise so it is easier for someone to answer and to not start a confusing thread.
According to previous posts, I want to warm the styrene in a pan of warm water, off the stove and set aside and not too hot to avoid flashing. I realize the danger and have a thermometer to monitor the heat. Paraffin melts at 85 F and styrene flashes at 115 F. I plan to grate the paraffin wax into the styrene and dissolve it. After it has cooled to ambient temperature, I will add the paraffin styrene mix into the home made pigmented filler topcoat. I am wondering if I should lessen the original amount of styrene in the gellcoat, because I will add the paraffin/styrene. I am thinking that may be too much styrene as a thinner, perhaps a thinner result is ok, not sure.
My question is using a scale to weigh the paraffin and styrene what is the percentage mix and how much of this mixture should I add to the polyester resin.
Threads about this varied in amounts and measuring methods, this is why I picked weight as the measuring standard.
Thanks so much!
