chalk prototype resin

[Sasso SP]

Bye to all,
I wanted to know if there is or are you aware of the relationship between resin and chalk prototypes?
I better explain myself having a 300g chalk prototype how much resin could absorb, exempt for lamination of glass fabrics, carbon etc. resin is equal to the weight of the laminar tissue.
Thank you.

if the plaster model treats it first with particular products such as silicone detachants and other absorption can be considered negligible.
as long as the amount of resin is requalified, it should not be equal to the weight of what you will apply. the glass or carbon fabric you will need to impregnate then apply. . . .
