Can sap of jackfruit be made into varnish?

Question

how many milliliters of sap can be made into varnish?

Answer 1

The heated latex of the jackfruit is employed as a household cement for mending china ware and earthen ware, and to caulk boats and holes in buckets. The chemical constituents of the latex is not a substitute for rubber but contains 82.6 to 86.4% resins which may have value in varnishes. Its bacteriolytic activity is equal to that of papaya latex.
