This article, the third in a series, covers work done to improve the water resistance of water-based emulsions by replacing conventional emulsion surfactants with surfactants that will react into the polymer matrix.
Carbon fiber composite material use is growing in sectors such as aerospace, wind power generation, automotive, and sports/leisure applications. Although corrosion and fatigue resistant, there is less known about the aging resistance of these materials. This study examines the commonly used ultraviolet absorbers, hindered amine light stabilizers, and a novel composite light stabilizer additive to get a better understanding of the weather resistance of carbon fiber composite materials in the industry.
A novel polymerizable surfactant was developed and utilized to prepare latex polymers and resins through emulsion polymerizations. These polymers were then evaluated in PSA and architectural waterborne coating formulations. The results showed that the new surfactant almost fully reacted during the emulsion polymerization, and reduced or even eliminated the free surfactant migration during film formation.
This article discusses the basic characteristics of phyllosilicate thickeners, and provides an introduction to understanding their performance in formulations in order to use them to build the rheological properties of latex paints.
The integration of pigments in coatings for autonomous vehicles presents a unique set of challenges ranging from functionality to aesthetics to regulatory compliance. In response to these needs, a new kind of effect pigment based on borosilicate glass was developed specifically for distinctive silver-grey formulations where a high sparkle is required and has a high radar transparency and offers dark-down flop and opacity.
As we reach the mid-point of 2024, there are a lot of questions surrounding market strength, trends, and challenges in the coatings industry. PCI recently interviewed Renata Rodrigues, Head of LANXESS Inorganic Pigments Americas, to get her input on the current state of the pigments segment of our industry.
A new wetting agent enhances wetting behavior, particularly in wood coatings. The innovative approach is based on a comparative evaluation of silicone-free and silicone-based surfactants, focusing on surface tension and contact angle.
By replacing fossil fuels with renewable resources, biomass balance products contribute to reducing greenhouse gas emissions and enabling a circular economy. BASF explains its Circular Economy Program in an effort to explain how the coatings industry and its approach to sustainability is changing and evolving to include the entire value chain.
588 exhibitors showcased their latest products and technology at the 20224 American Coatings Show in Indianapolis. Read PCI’s show wrap-up article to get a glimpse of just some of the new products available to coatings formulators.
The coatings use a rotogravure printing process to impress natural elements onto the metal substrate during application, allowing for an unlimited array of patterns and rich multi-layer effects.
The new modified cycloaliphatic epoxy curing agent addresses current performance gaps of existing products and offers good balance of fast cure speed with strong carbamation, water-spotting, and chemical resistance.
Eaton has enhanced its filter cartridge portfolio to better align with market needs. In addition to optimizing the portfolio, delivery times for ideal supply have also been significantly reduced.
Increased market demand for fluorine-free, water-repellent technical textiles is projected to reach USD 605.1 million by 2029. A new performance coating helps meet this demand, harnessing the company’s proven polymer technology.
It has been a busy show season, with PCI recently returning from the American Coatings Show (ACS) in Indianapolis, the RadTech 2024 UV+EB Conference in Orlando, and CPCA’s Canadian Coatings Conference in Montreal. All three events were energetic, and introduced great new information and technology for the coatings industry.
