Selection Guide

What to do about rusting workpieces, corroded guideways, and darkening/graying aluminum parts in waterborne cutting fluids? This article clarifies the difference and coordination between rust prevention and corrosion inhibition: rust preventives for ferrous metals, corrosion inhibitors for non-ferrous metals (Al, Mg, Cu); in multi-metal systems, select by material (Vanconol® ALI-910, MGR-82/83, CPI-AP, etc.), with pH and concentration management tips. Data subject to TDS.

This article discusses how to achieve high retention of carbon black in papermaking color pastes through proper selection of high-performance polymeric dispersants, with a focus on Toynol® DS series products from Tianjin Hi-Perferal Advanced Materials Co., Ltd.

This article analyzes challenges in dispersing graphite slurries and presents a selection approach combining dispersants and suspension stabilizers, using Toynol® DS series dispersants and AN series suspension stabilizers as an example, with final product selection based on TDS and actual testing.

Foam in electrodeposition (cathodic/anodic) paint baths can cause craters, pinholes, and uneven film thickness. This article explains foam sources and risks, compares polyether, silicone, and mineral oil defoamers, outlines a selection pathway and dosing tips (small, frequent additions, pre-dilution, lab-scale testing), and references the Toynol® DF/Foamic series as options. Actual data should be verified with the TDS.

A guide to selecting wetting, leveling, and defoaming agents for waterborne non-stick coatings, addressing challenges on low-energy surfaces.

This guide provides a fast-track sample request process for Toynol® products (FS-6502, Superwet-604, Superwet-320) as direct replacements for Surfynol® series, with detailed benchmarking recommendations and testing procedures.

A comparative guide on defoamer selection for waterborne coatings and industrial water treatment, covering foam-breaking speed, foam-suppression durability, compatibility, and cratering risk, with application-matched recommendations and dosage principles.

Carbon black, with its fine particle size, high specific surface area, and strong electrostatic agglomeration, is one of the most challenging pigments to disperse in waterborne pigment concentrates and conductive pastes. This article analyzes the difficulties of carbon black dispersion, outlines a selection path for dispersants, and provides a practical approach to conducting small-scale gradient trials for Toynol® DS series based on their TDS, including common pitfalls and FAQs.

Wetting agents address powder wetting and substrate spreading, while dispersants ensure long-term particle dispersion stability. This article compares their mechanisms and selection criteria, and presents a recommended combination path using Toynol® FS-204 acetylenic diol, Superwet series, and DS/ADS dispersants, along with common pitfalls.

The key indicator for selecting wetting agents in waterborne coatings is dynamic surface tension: it directly affects powder wetting, grinding efficiency, and dispersion stability. This article explains the mechanism of wetting agents, compares three types of surfactants (acetylenic diols, polyethers, silicones), and provides selection pathways and common pitfalls for Toynol® FS-204 and Superwet series.
