W´Add 915 is a powder coating additive capable of improving mechanical properties of powder coatings and their surface appearance.
W´Add 915 is a free flowing powder which is convenient in handling, easy to disperse and reliable in performance. For best results W´Add 915 should be pre-blended with other coating ingredients in a high-intensity mixer, then homogenized in an extruder.
W´Add 915 should be used at concentrations of 1.5 - 2.5% based on the resin used.
W´Add 915 is especially developed for W´Cryl CP 550 or GMA-300 based powder coatings.
W´Add 915 should always be used in combination with Resiflow PV 88 or an equivalent flow control agent.
