Abstract

The present disclosure provides, in part, a solvent composition for use as a replacement for slow evaporating solvents. The solvent composition may include para-Chlorobenzotrifluoride (PCBTF), a methylated organosilicon compound, and a carbonate ester.

Claims (33)

1. A solvent composition comprising:

i) para-Chlorobenzotrifluoride (PCBTF) comprising about 60% to about 65% by volume of the solvent composition;

ii) a methylated organosilicon compound comprising about 23% to about 50% by volume of the solvent composition; and

iii) a carbonate ester comprising about 0% to about 12% by volume of the solvent composition.

2. The solvent composition of claim 1 wherein:

i) the methylated organosilicon compound comprises about 25% to about 30% by volume of the solvent composition; and

ii) the carbonate ester comprises about 10% to about 12% by volume of the solvent composition.

3. The solvent composition of claim 1 wherein the methylated organosilicon compound or the carbonate ester is VOC-exempt.

4. The solvent composition of claim 1 wherein the carbonate ester is propylene carbonate (PC).

5. The solvent composition of claim 1 wherein the methylated organosilicon compound is hexamethyldisiloxane (HMDS), octamethyltrisiloxane (OMTS), or decamethyltetrasiloxane (DMTS).

6. The solvent composition of claim 1 wherein:

i) the para-Chlorobenzotrifluoride (PCBTF) comprises about 60% by volume of the solvent composition;

ii) the methylated organosilicon compound is decamethyltetrasiloxane (DMTS), and comprises about 28% by volume of the solvent composition; and

iii) the carbonate ester is propylene carbonate (PC) and comprises about 12% by volume of the solvent composition.

7. The solvent composition of claim 1 wherein:

i) the para-Chlorobenzotrifluoride (PCBTF) comprises about 63% by volume of the solvent composition;

ii) the methylated organosilicon compound is decamethyltetrasiloxane (DMTS), and comprises about 27% by volume of the solvent composition; and

iii) the carbonate ester is propylene carbonate (PC) and comprises about 10% by volume of the solvent composition.

8. The solvent composition of claim 1 wherein:

i) the para-Chlorobenzotrifluoride (PCBTF) comprises about 65% by volume of the solvent composition;

ii) the methylated organosilicon compound is decamethyltetrasiloxane (DMTS), and comprises about 25% by volume of the solvent composition; and

iii) the carbonate ester is propylene carbonate (PC) and comprises about 10% by volume of the solvent composition.

9. The solvent composition of claim 1 wherein the solvent composition has a calculated flash point of at least 50° C.

10. The solvent composition of claim 1 wherein the solvent composition has a calculated evaporation rate of at most 0.7.

11. A kit or commercial package comprising the solvent composition of claim 1 together with instructions for use.

12. The solvent composition of claim 1 wherein the solvent composition is for use as a replacement for slow evaporating solvents.

13. The solvent composition of claim 1 for use as a replacement for mineral spirits, methyl amyl ketone (mak), cyclohexane, n-butyl acetate, Aromatic 100 or Aromatic 150.

14. The solvent composition of claim 1 for use as a solvent.

15. The solvent composition of claim 1 for use as a primary or co-solvent for paints, varnishes, coatings, inks, or adhesives.

16. The solvent composition of claim 1 for use in the manufacturing and/or formulation of paints, varnishes, coatings, wood preservatives, lacquers, or varnishes.

17. The solvent composition of claim 1 for use as a paint thinner, paint remover, cleaner, degreaser, and/or adhesive remover.

18. The solvent composition of claim 2 , wherein the carbonate ester is propylene carbonate (PC).

19. The solvent composition of claim 2 , wherein the methylated organosilicon compound is hexamethyldisiloxane (HMDS), octamethyltrisiloxane (OMTS), or decamethyltetrasiloxane (DMTS).
