Hi everyone, there is a formula to prepare putty paste?, like the soft one used in automotive, soft, sandable. In my shop I have Cabosil, hollow microespheres, polyester resin, dma, peroxide, talc powder, etc. I have tried some personal preparations, but no succes.

It's good stuff and cheap enough. I agree, but sometimed I need putties with specifics resins and fillers. You would need to make yourself some practice samples but basically I would start with your preferred resin with 2-4% wax in styrene monomer, mostly a Q cell or microsphere filler. Then your catalyst. Mix it up and try it out. ok thanks, and a thixotropic like Aerosil? You can add a thixotrope like aerosil or cabosil if needed but these will make the filler harder to sand. It's a bit of balance, add enough fillers and the material becomes light enough not to sag/run. Polyester flow coat and gelcoats with wax make for good filler resins too. |
