ISP Exhibits Its Innovative Microbial Control Additive at ECS 2011

Published on 2011-03-31. Author : SpecialChem

NUREMBERG, Germany -- At the European Coatings Show, ISP Performance Chemicals introduced a new microbial control additive designed to resolve tradeoffs in dry-film protection strategies and a wet-state preservative engineered to replace formaldehyde containing products previously used in Europe for in-can protection against microorganisms. Fungitrol® 940CR fungicide, based on the controlled release of IPBC (active) through microencapsulation into an inorganic carrier, is an all-new technology expected to change the way coatings makers protect dry-film from microbial defacement. Nuosept® BIC, a high-performing formaldehyde-free in-can preservative offered as a "drop-in" replacement to formaldehyde containing preservatives, will serve as a universal biocide for wet-state preservation. ISP also put on display high-performing wood care chemistry, including its SunCare™ range of lignin protection additives and WetCare™ extreme hydrophobicity additives. Focusing on high-value solutions, the company presented select Jaypol™ polymers based on acrylate technology in support of advances in the performance of water-based coatings. ISP's David K. Hood, Ph.D, R & D Manager, Performance Chemicals, Applications and Development, presented a novel coating design based on the crosslinking capability of water-soluble polymers. All ISP product offerings and technologies displayed at ECS 2011 address industry requests for technologies engineered to improve the performance and efficiency of coatings at lower overall cost.

According to Scott Edris, Sr. Director Global Marketing Performance Chemicals, just like other high-technology industries, the paints and coatings industry is looking at ways to improve the attributes of product offerings at a lower total cost for competitive advantage. "The Performance Chemicals business of ISP recognizes innovation is the most valuable attribute a supplier can provide to formulators of paints and coatings," he said. "That's why we are an R&D driven business, continually bringing new ideas into the laboratory for testing and commercialization. The all-new Fungitrol 940CR is a game-changing technology, providing formulators better, more sustainable dry-film protection strategies. Nuosept BIC wet-state preservative is another high-performing product with excellent efficiency in a formaldehyde-free, water-based dispersion. Both products are closely aligned with market and regulatory trends."

Introducing Fungitrol 940CR

ISP announced the launch of Fungitrol 940CR fungicide for dry-film protection of paints and coatings at ECS 2011. The new offering is designed to deliver a minimum amount of fungicide to the coating interface over an extended period of time. Based on the controlled release of IPBC (active) through microencapsulation into an inorganic carrier, Fungitrol 940CR may be used to resolve tradeoffs in dry-film protection strategies and to enhance the overall performance of fungicide in use.

According to Karen Winkowski, Sr. Director of Performance Chemicals and Biocides Applications, with the launch of Fungitrol 940CR, paint makers will have better options to maintain coatings free of microbial defacement without relying on high biocide loading levels. "Traditionally, high levels of biocide are added to formulations to ensure a sufficient amount of biocide migrates to the coating surface interface, where they exert their biocidal effect," she said. "Yet this strategy also renders the biocide susceptible to water leaching under humid conditions and to typical environmental degradation processes, such as UV and heat. We found that by controlling the release of IPBC through encapsulation technology, a minimum concentration is always present at the surface interface."

Nuosept BIC Wet-state Preservative for Europe

At ECS, ISP announced the launch of Nuosept BIC, a high-performing formaldehyde-free in-can preservative offered as a "drop-in" replacement to formaldehyde containing preservatives. The water-based, zero VOC, formaldehyde-free preservative contains three active substances (BIT, IPBC, CMIT/MIT) that work synergistically to preserve products against a broad variety of microorganisms. Engineered with quick kill activity, ISP will market Nuosept BIC as a universal biocide for wet-state preservation, with the added benefit of plant hygiene. The new biocide formulation has been made commercially available in Europe for formulators of paints, coatings, adhesives, ready mix building materials and construction chemicals that seek to market Ecolabel compliant products without compromising the quality of wet-state preservation.

According to Gilles Pradier, Industry Manager, Paints & Coatings Market EMEA, the changing market dynamics for biocides presented ISP with an opportunity to formulate new products that better serve the needs of formulators, and at the same time, fulfill regulatory requirements. "Formulating Nuosept BIC as an Eu-Ecolabel compliant, water-based dispersion with excellent performance and efficiency has provided the paints and coatings industry a wet-state preservative solution with excellent value propositions," he said. "The unique combination of BIT, IPBC, CMIT/MIT offers long-term and quick kill activity with very low use levels, allowing for its use as a universal wet-state preservative and plant hygiene technology. Beyond this, the biocide conforms to the European Ecolabel, providing makers of interior and exterior coatings the ability to meet regulatory requirements without formaldehyde donor technology. A major improvement over legacy preservatives, the European paints and coatings industry has several reasons to adopt Nuosept BIC as a platform preservation technology."

Reactive Polymers for Aqueous Inkjet Coatings

Formulating reactive polymer coatings as aqueous solutions that perform well and remain stable under adverse conditions is a major focus of research scientists at International Specialty Products (ISP). At the European Coatings Congress in Nuremberg, Germany, Dr. David K. Hood, presented a novel coating design based on the crosslinking capability of water-soluble polymers. The author examined the structure and functions of these materials in sample coating formulations and discussed their potential in next-generation UV curable coatings.

According to Dr. David Hood, overcoming formulating challenges associated with aqueous-based UV curable coatings has the potential to expand the commercial application of a very desirable product form. "Traditional UV coatings formulations offer very robust and durable coatings performance," he said. "Extending that performance to new, novel UV curable coatings can conceivably change the way inkjet printing systems are made and sold. In our paper called "A Novel UV Coatings Design and Application in Curable, Aqueous Based Inkjet Printing Systems," we looked at the molecular structure of an uncommon lactamic monomer coupled with strong water soluble polymer and examined its potential in the areas of gloss, film forming, dye fixation properties and print receptivity."
