Paint and Coatings Additives

In this article we report on the development of a tin-free aqueous silicone gum dispersion from early tin-based compositions.

By combining an advanced polymeric additive structure with macromonomer functionality with functional groups that can covalently bond to an epoxy system, a new type of additive with superior properties could be generated.

By understanding how additive performance can be affected by formulation change, formulators can identify potential problems and work with their suppliers to find answers faster.

The low-VOC coalescents investigated in this work presented high affinity for vinyl-acrylic and acrylic latexes and ability to decrease their MFFT.

This article reports on our evaluation of AMPARMOR™ 2000, an additive designed to impart self-healing functionality to fusion-bonded epoxy (FBE) and epoxy powder primer coatings, and AMPARMOR 3000, designed as an option for nonepoxy coatings.

Depending on the nature of the application, different levels of the release effect are desired, and demands regarding durability of the release effect vary substantially. Therefore, it makes sense to take a closer look at the specialty additives that create this effect.

Tomorrow’s paints and coatings can be much more than a pretty surface. Many of them will be smart, functional materials that respond to, and change, the environments around them.

Defoamers are chemical additives that reduce and/or prevent the formation of foam in industrial process liquids such as paints, inks, adhesives and even construction products.

In this study a higher number of cells were recovered from a diluted, low-nutrient medium than from the undiluted, nutrient-rich medium.

This new silica technology addresses longstanding challenges in manufacturing and also avails a new range of functional silica and silicate products with unique performance profiles that help formulators realize new value in synthetic silica technology.
