Nano-Scale UV Protection Additive for Water-Based Coatings Systems
The Performance
Chemicals business of ISP introduced a new technology for protecting the
integrity of coatings from damage caused by UV radiation. Called SunCare
Topcoat, this new technology is based on nano-scale emulsions of UV-protective
actives offering broad spectrum protection (290 to 380 nm) with outstanding
performance in the UVA range. Tests have shown that SunCare TopCoat can be up
to four times more effective than traditional water-based coating UV-protection
additives. This breakthrough performance results from the use of dramatically
smaller particle sizes of the UV active, with better particle distribution in
the emulsion. Applications for SunCare Topcoat include exterior wood stains and
varnishes, indoor wood coatings and wood care products, plasters, plastic and
leather care products, UV blocking varnishes on printed materials and adhesives
and bonding layers. SunCare Topcoat is an extension of the line of wood care
technology launched by ISP in 2009. The ingredient will be initially sold in
Europe, the Middle East and Asia.
According to Scott Edris, Senior Director of Global Marketing, Performance & Agricultural Chemicals, SunCare TopCoat is the result of an initiative at ISP to create new technology for manufacturers of wood care products and is a perfect example of the company’s broadening product portfolio for the coatings industry at large. “In the last few years, ISP has set its sights on broadening and improving coatings technology for customers. While additives have always been a part of our portfolio, we have expanded the ways we can help coatings manufacturers improve their products by adding a full range of biocides, new acrylates chemistry and technically sophisticated products like SunCare TopCoat,” he said. “While we see SunCare TopCoat as being most attractive to companies that make wood coating and wood protection products, we feel this technology will be attractive to a broad range of coatings manufacturers who want to ensure long-term product integrity against the potential damage of UV radiation on anything they make. The efficiency and economics available with SunCare TopCoat can help make this happen,” he said.
The high level of performance of SunCare TopCoat allows lower use levels – offering economic efficiency and a lower environmental profile. SunCare TopCoat is VOC and surfactant-free. ISP conducted tests with SunCare TopCoat that show it works synergistically with other products within ISP’s wood care technology line – specifically SunCare UV and SunCare 800. Both of these products are lignin stabilizers that prevent degradation of wood in primer formulations. Tests using both primers and topcoats featuring SunCare products have shown exceptional performance in the field.
According to Edris, wood care technology from ISP is created to improve performance and durability, ease formulation challenges, and deliver on the promise of value. “With a rise in the performance parameters of our additives, ISP has a great deal of exciting, advanced solutions for the wood coatings producer,” he said.

Patent Pending, Advanced Technology for Water-Based Systems
SunCare TopCoat is a stabilized combination of UV-absorbers and Hindered Amine Light Stabilizers (HALS) – offering double action for maximum effectiveness. The patent pending microemulsion technology represented in SunCare TopCoat is responsible for most of its advanced properties, including excellent binder and dry film protection across a very broad spectrum of UV radiation. SunCare TopCoat's performance, however, stands out in the UVA range.
