Does somebody know the composition of sealing wax?
Rosin 39%; Shellac 26%; Titanium oxide 26%; CI pigment 3% & PE wax 6%.
In addition, this wax is too brittle, any chnages on the % make changes on the brittleness?
Answer:
Anything wrong with just paraffin wax?
Or a modified paraffin, as in US Patent 4013188:
The preferred ranges of hot melt paraffin-based resin composition components will be as follows: Paraffin Wax 45-82.5% (MP 143.degree.-145.degree.F) Co-polymer of ethylene and 12.5-25% vinyl acetate -- Elvax 260 Piccotex 120 * (resin co-polymer 5-25% of vinyl toluene with alpha methyl styrene).
This formulation should have improved characteristics with regard to tensile strength, formability, temperature-viscosity curves, and resistance to sharkskin-type deformations.
This sounds like a formula for sealing wax for letters; it is supposed to be hard and brittle.
Maybe you are looking for something that is more like a putty, or a sticky, rubber-like material? If you could tell what the final application is, people could better help you with finding the optimum product.
