maybe HCOOH? Silicon often smell of this.
NO and NO.Silicon is an element and does not smell of formic acid.Silicone sealants are often formulated with Methyltriacetoxysilane as a cross-linker which releases acetic acid, CH3COOH, during curing.The mask started off as a liquid that reacted to give a cross-linked solid. Now you have a solid you can not modify the shape.
