Latest Development in Energy Curable Resins for Hardcoat Application

Energy curing of acrylated resins is a well established coating technology gaining further market acceptance for the protection and decoration of surfaces in many applications like furniture, flooring, construction, printing inks and others. Compared to conventional thermally-cured coatings, energy cured coatings offer the additional benefits of lo

UV-cured hybrid sol-gel coatings for aeronautical and Direct-To-Metal (DTM) applications

Corrosion protection in the aeronautic industry is a key issue. Nowadays, multilayer coatings are used to protect aeronautical metallic substrates. A typical system contains hexavalent chromium, or chromate, to provide high active corrosion protection, and is made up of three layers applied on a previously prepared surface. However, hexavalent chro

Development of new UV-curable paints for metal using high-throughput technologies

Besides the increase of productivity, the reduction of energy costs and the absence of solvent release, UV technology brings extra added value to metal for specific applications by obtaining a synergy of excellent coating properties like surface hardness, abrasion, chemical and corrosion resistance while still allowing the necessary adhesion and fl

Surface Energy Study of UV-Curable Patterned Surface Involved Nano Silica Treated with Perflourosilane

Wettability of a surface are characterized by the static contact angle, made between a water droplet and surface. A surface is hydrophilic if the contact angle is less than 90° and the surface is hydrophobic if the value of the contact angle is greater than 90°. Surfaces with the contact angle between 150° and 180° are called superhydrophobic. The

Polymeric Hydrogels Sythesized via Photopolymerisation and Photocrosslinking

Polymeric hydrophilic gels (polymeric hydrogels) are networks of polymer chains comprising a strong hydrophilic crosslinked structure [1]. Polymeric hydrogels can absorb and retain significant amounts of water (> 20 wt.%) within their structures without dissolving into the water [2]. Hydrogels are useful as scaffolds in tissue engineering applic

Control Release Additives and Peel Release Values of Silicone Release Coatings

Most release coatings are silicones, usually crosslinked PDMS-type materials. Silicones dominate the market: they have excellent anti-stick properties. These properties originate from the a low surface tension of silicones and flexibility of Si-O-Si bond.1 Industry uses test tapes to measure an important property of silicone release coatings or sil
