3M PPS mix ratio inserts are re-usable mix inserts designed for the 3M PPS 1.0 paint preparation system, so every mix sits in a consistent interface between the PPS hard plastic cup and the disposable liner. Each insert is placed between the hard cup and the PPS flexible liner, which positions the printed mixing ratios directly where material is measured and mixed. The inserts show common mixing ratios, providing an immediate visual guide while tint, reducer, and catalyst are added. This layout supports repeatable mix accuracy when you are working with the PPS system in a shop environment. The PPS name identifies a paint preparation setup used in industrial and occupational settings, so these inserts support that workflow where single or repeated batches are mixed during finishing or refinishing work.
The PPS system consists of a hard plastic cup that supports and holds the PPS flexible liner, so the mix insert operates inside a rigid outer shell while the liner holds liquid material. A lid with a built-in 200 micron filter and a locking collar completes the PPS system structure, so material mixed against the insert is then covered and filtered within the same setup. Because the mix inserts are re-usable, a shop can keep them in rotation during multiple mixing tasks through the day. The printed mixing ratios remain inside the PPS system where the liner is filled, so technicians track levels directly against ratios while they pour and adjust materials.
The PPS 1.0 mix ratio inserts are specified for use within the PPS system, which is a paint preparation layout using a hard plastic cup, a flexible liner, a filtered lid, and a locking collar. Within this setup, the insert is positioned between the hard cup and the disposable liner, so the ratio markings are viewed through the liner wall while liquid is added. This relationship keeps the liner supported by the cup while the ratio information remains fixed in one place, even when the liner is changed between mixes. Because the inserts show common mixing ratios, they function where mixing ratios must be read quickly during paint or stain preparation for industrial or occupational tasks.
The inserts are described as re-usable, which means they are intended to stay in service across repeated mixing sessions inside the same PPS 1.0 hard cup and liner configuration, supporting a consistent visual reference for every batch. The PPS system description states that a lid with a built-in 200 micron filter and a locking collar is part of the system, so material mixed using the insert can then move directly into a filtered, secured container without shifting to another cup, helping preserve the original ratio during handling. By placing the insert between the hard plastic cup and the PPS flexible liner, the design keeps ratio markings protected from direct contact with liquid while still readable through the liner, so splashes and residue on the inner liner have less impact on long-term legibility. Because the inserts show common mixing ratios used with coatings, they connect directly to the way materials are prepared in shop and safety supply environments where paint and stain supplies are managed as part of a controlled workflow.
The PPS 1.0 mix ratio insert is used inside the PPS hard plastic cup and flexible liner to display common mixing ratios, so painters can mix coatings to specified proportions directly in the PPS system.
The mix insert is placed between the hard plastic cup and the PPS flexible liner, so it stays fixed while the liner holds liquid and the operator reads ratios through the liner.
PPS 1.0 mix ratio inserts are described as re-usable, so the same insert can serve through multiple mixing cycles in the PPS setup, supporting consistent ratio reference in ongoing work.
These PPS inserts show common mixing ratios, so coating components can be combined to standard proportions without relying on a separate chart or external reference near the mixing area.
The insert supports accurate mixing inside the cup and liner before the PPS lid with a built-in 200 micron filter and locking collar is applied, so mixing and filtering occur within one system.
These PPS inserts are part of a PPS system described for industrial and occupational use, so they are intended for workplace paint and stain preparation rather than general home or recreational use.
The PPS 1.0 mix ratio inserts with part number 50051131160915 are specified for the PPS system, where a hard plastic cup, flexible liner, and filtered lid support paint preparation in industrial and occupational settings. Because the inserts are re-usable and sit between the hard cup and disposable liner, they provide a stable visual guide to common mixing ratios across repeated batches. For shops using the PPS paint preparation layout, this insert design supports controlled mixing steps that match the PPS workflow.
