What types of diluents should be avoided with liquid silicone?
Sulfur/nitrogen-containing solvents, such as sulfides and amines, can inhibit the platinum catalyst in addition-type inks, leading to curing failure.
Highly polar or corrosive solvents, such as acetone, toluene, and xylene, can damage the silicone's molecular structure, causing cracking and decreased adhesion after curing. They are also highly toxic.
Solvents containing excessive amounts of water or alcohol, such as methanol and ethanol (high water content), can interfere with the curing reaction of condensation-type inks, resulting in a non-drying surface.
