ALKYD CALCULATIONS VERY USEFULL WHEN WE DESIGN AN ALKYD. I PERSONALLY USED THESE CALCULATIONS AND DESIGNED MANY ALKYDS SUCCESSFULLY. THESE ARE ALL AVAILABLE IN T.C. PATTON BOOK.
ON THE BASIS OF THESE CALCULATIONS I PREPARED AN EXCEL SPREADSHEET WITH FUNCTIONS, SO THAT WHEN WE ENTER FORMULATION INSTANTLY WE GET ALL CALCULATED RESULTS. IF YOU ARE INTEREST, PLEASE SEND ME AN EMAIL FOR EXCEL SHEET OF ALKYD CALCULATIONS.
