I prepared a hydrophobic water based latex paint. Because of the the additive i used in the paint for the modification, it is getting harden within few weeks. I used hexa decyl tri methoxy silane as a additive here. Can anyone suggest a method to improve the shelf life of the paint please?

PERSONALLY ,MORE THAN AN OXIDATION PROBLEM I´M THINKING ABOUT A REACTION BETWEEN THE SILANE GROUP AND ANY OTHER SUBSTANCES CLOSE TO THE LATEX POLYMER.
COULD BE A POLYMERIZATION,MAYBE?

Another option would be flocculation proceeding (would need stabilizer) or continued polymerization process (reduce initiator amount).

Proper pH range must be maintained (i.e. slightly acidic) to avoid silane condensation
