(FAS55)Mixing lids introduce a new central seal that will help prevent oozing that is common to waterborne paints. Oozing occurs when the paint creeps upwards- though the central seal- spilling onto the lid body. The problem might worsen if the paint isn t shaken before the toner is installed onto the machine because the natural separation will adversely impact the strength of the toner. Our new central seal will reduce this likelihood by forcing paint back inside the can while the machine is running. Lids feature a redesigned pouring spout for faster, non-clogging dosing, and soft-touch locking cams to make can changes easier. Fillon lids are a great investment. Painters will appreciate the close attention to detail, comfortable pouring, and dosing accuracy. Innovative central shaft seal the nearly eliminates oozing with waterborne paints. Optional anti-adhesive skates to reduce paint residue and improve performance. Smooth dispensing action with pin-point control pouring. Compatible with solvent and waterborne paints.
