Several properties of coatings are the subject of improvement. Often, those properties are directly related to the composition of the resin system and the specific application of the paint. It turns out that polysiloxanes<\/strong><\/a>, often called silicones<\/em><\/a>, can be used to improve a variety of coating properties. This article is about improving the outdoor durability<\/a> of coatings by combining organic resins and polysiloxane1<\/sup>.<\/p>\n

Outdoor durability<\/strong><\/p>\n

Outdoor durability of coatings, often called weatherability<\/strong><\/a> or exterior durability, refers to the resistance against degradation during outdoor exposure. Photo-oxidation<\/strong>, caused by the UV component of electromagnetic radiation from the sun, and hydrolysis<\/strong><\/a> of the resin system are important processes during the deterioration of coatings during outdoor exposure2<\/sup>. A coating can yellow, crack, lose gloss, or lose adhesion because of degradation.<\/p>\n

\"\"<\/p>\n

Cracking and loss of adhesion of a coating caused by exterior exposure<\/em>.<\/em><\/p>\n

The speed of degradation of a coating during outdoor exposure depends, amongst others, upon two key factors. First, the strength of the bonds in the resin system is important. The higher the bond energy<\/strong>, the more difficult it is to break the system down. Secondly, the degree of UV absorption<\/strong><\/a> by the resin governs how many radicals can be formed during exposure of the coating to sunlight. Radicals act as the ‘scissors’ for chemical bonds during photo-oxidative degradation of coatings.<\/p>\n

Most resins that are used for paints, like alkyds<\/a>, polyesters<\/a>, polyacrylics<\/a> and epoxies<\/a>, are organic polymers<\/strong> that are based on carbon (C<\/strong>) chemistry. Even though biobased raw materials become more important, most of the raw materials used to make organic resins come from fossil sources. Organic resins have limited resistance against UV radiation, heat and hydrolysis.<\/p>\n

Key properties of polysiloxane<\/strong><\/p>\n

When looking at durability, an interesting alternative for pure organic resins is to use inorganic polymers that are based on silicon (Si<\/strong>) chemistry, like polysiloxanes<\/strong><\/a>.<\/p>\n

\"\"<\/p>\n

General structure of linear polysiloxane.<\/em><\/p>\n

The backbone of polysiloxanes consists of silicon and oxygen atoms. The side groups (R<\/strong>) are organic groups, most often methyl and\/or phenyl.<\/p>\n

\"\"<\/p>\n

Key characteristics of polysiloxanes, compared to organic polymers.<\/em><\/p>\n

Two key properties of polysiloxanes<\/a> can be directly linked to the excellent outdoor durability of these polymers. First, the bonds in the polymer backbone are strong, implying that a high amount of energy is needed to break the backbone down. Secondly, polysiloxane is nearly transparent to UV radiation.<\/p>\n

How to use polysiloxane in coatings?<\/strong><\/p>\n

The concept that is often used, when durability must be improved, is that part of the organic resin is substituted by polysiloxane. The durability of a resin improves when the polysiloxane content is increased. Polysiloxanes of low molecular weight, so-called polysiloxane oligomers<\/strong><\/a>, can be used as building blocks in the synthesis of resins that are used in paints. The branched, 3-dimensional polysiloxanes contain functional groups, most often hydroxyl (–<\/strong>OH<\/strong>) and\/or methoxy (–<\/strong>OCH3<\/sub><\/strong>) groups, that can react with hydroxyl groups of organic resins. Typically, the co-condensation of the organic and inorganic polymers is done in a reactor at around 150 \u00b0C.<\/p>\n

\"\"<\/p>\n

Co-condensation reactions of polysiloxane with organic resins.<\/em><\/p>\n

Alkyd resins<\/a>, polyester resins<\/a>, epoxies<\/a> and polyacrylics<\/a> with improved durability can be made in this way. The resulting resins are said to be inorganic-organic hybrid<\/strong> resins<\/a>. The more polysiloxane is used, the higher the inorganic content of the resin is and the better the resistance against UV radiation, heat and hydrolysis becomes. The polysiloxane content of siliconized alkyd resins, used for exterior architectural paints, is typically in the range of 15 to 35 weight-%.<\/p>\n

\u00a0An example:<\/strong><\/p>\n

Several companies supply polysiloxane oligomers that can be used as building block in the synthesis of resins to obtain hybrid binders with improved durability. SILRES\u00ae<\/sup> IC 368<\/a> of Wacker Chemie AG<\/a>, being a global leader in silicon chemistry, is an example of such a product.<\/p>\n

\"\"<\/p>\n

Key characteristics of SILRES\u00ae<\/sup> IC 368.<\/em><\/p>\n

SILRES\u00ae<\/sup> IC 368<\/a> is a solvent-free liquid polysiloxane oligomer, that can be used as building block to modify organic polymers, such as alkyds<\/a>, polyesters<\/a> and polyacrylics<\/a>. During synthesis, the methoxy groups (-OCH3<\/sub>) of the polysiloxane react with hydroxyl groups (-OH) of the organic resin. The resulting siliconized resins, being inorganic-organic hybrid polymers, can be used as binders for coatings that have improved resistance against weathering, hydrolysis and heat.<\/p>\n
