Solubility

Sanho Chemical TOHMIDE 92 Solubility

** (A) Solution stability：Each sample solution, after once completely dissolved, was left standing overnight at the designated temperatures, and then was observed.
S：stable, SG：soft gelled, G：gelled
** (b) Gel recovery： Time(in minutes) needed for each of the once gelled-up solution to fully recover fluidity at 25℃.

INK TEST -Ink Formulation

 

  • Polyamide resin ：12.0 Parts by Weight
  • Phthalocyanineblue pigment ： 7.5
  • Nitrocellulose. “L-1/8 sec.”(=30％ wetted by isopropanol) ： 3.0
  • Isopropanol ：27.0
  • Ethyl-acetate ： 1.5
  • Ethyleneglyool - monoethylether ： 1.5
  • Total ：52.5
  • About formulation was prepared to ink by a ball milling.
INK TEST -Testing Conditions
  • Water resistance ：Each sample ink was printed onto an treated polyethylene film. The sample print was then immersed in tap water for 16 hours at room temperature. Afterwards the ink film was subjected to “Scotch Tape-Test” with the excess water wiped off.
  • Oil resistance ：Margarine was coated onto the sample prints of treated polyethylene substrate, and 16 hours later, “Scotch Tape-Test” was conducted. 
  • Heat (-sealing) resistance：Heat-sealing bar, with the load of 1 kgr./㎝ 2 , was applied onto the sample ink film on treated polypropylene for one second.
  • Anti blocking test ：The sample inks were printed on treated polyethylene film of an aluminum foil. The ink films were then subjected to static load of 1 kgr/㎝ 2 , for 16 hours under a condition of 50℃, R/H=50％
