W´Add 361 hammertone additive is a 10 % solution of a special silicone in xylene. It imparts a hammertone finish to wide variety of air drying, force drying and stoving coatings.
0.1 - 0.5% W´Add 361 is the recommended addition for air drying or stoving hammer finishes. It is not necessary to add an other silicone oil. Proper control of additive concentration, paint viscosity, spraying conditions and solvent use, all contribute greatly to the type of hammertone finish desired. W´Add 361 is usually added to the coating during the final thinning step.
In some water-borne systems, W´Add 361 is recommended for evaluation provided the additive is incorporated with the resin prior to the let-down stage.
