3 Teknos in brief A leading European manufacturer of industrial coatings A strong position in consumer and professional coatings Production in 7 countries: Finland, Sweden, Denmark, Germany, Poland, Russia and China Teknos sales companies in 16 countries, dealers in more than 20 countries Turnover in million 1,200 employees out of which 190 in R & D Industrial paints account for 75% of turnover One of Finland s largest family-owned businesses

4 Wood constructions 2016 Wood - construction material of the future Green economy - green building - cleantech Construction > produce 40 % of carbon dioxide (CO2) emissions Low logistic costs When a tree is growing one cubic, it burns at the same time 1000 kg of CO2 and produces 700 kg of oxygen (O2) Wood is renewable material The yearly growth of forests in Finland exceeds 40 % the usage of forests Wood is cheap, fast, light and easy building material Markets need more ready and sophisticated systems

7 DEMANDS CONCERNING CLADDING PAINTING AND RELATED Fine sawed, brushed, rifled or planed All the surface has to be roughed Vertical / horizontal claddings Demands concerning air gaps Different dimensions (18-42 mm) Wood species Surroundings Opaque / transparent systems Geographical location affects the requirements of paint systems Warranties, the constructor has to give warranties Warranties, the constructor has to give warranties (10-20 Years)

8 The basics of industrial painting of claddings - Industrial painting started in In Norway there has been a lot of problems with painting of claddings on construction place - VTT research (1992) showed that the time between planing and painting had big influence to adhesion - Today over 85 % of claddings is painted industrially in Scandinavia

10 Wood humidity and pitch We see following value adding timber industry products interesting for Teknos Humidity of wood 1. Outdoor claddings humidity % Interior panels Windows, doors, mouldings Flooring boards 7 Pitch After a tree is chopped down, it has 4-6 weeks time to be processed to make the product ready (windows, panels). Such a short time causes problems with knot yellowing. Pitch don t have time for crystallisation. This is an actual problem especially when the tree is chopped down in spring (spring wood) Resins are water soluble, which means that at high humidity and high temperature the yellowing is more common

11 Industrial painting of claddings in Finland In Finland the painting of claddings on construction place is regulated by RYL 2012 Industrial painting is regulated by RT Industrial painting has to happen in 60 hours after planing After painting the painted panels has to be stored 24 hours inside Primer has to be mainly alkydbased paint, application min. 50 g/m 2 There need to be instructions for transportation, storing and service painting in every package Controlled even quality Stable conditions and controlled process Industrial topcoating mainly with acrylic paints Today almost all the claddings in Finland are at least industrially primed At the moment over 30 % of claddings are also industrially topcoated CE-marking is obligatory from for claddings at EC

12 Opaque systems for claddings Examples according to RYL (Use /hazard/ class 3.1, according to EN 335-2) OPAQUE SYSTEM 1. Industrial priming 1 x TEKNOL 1881 / 2881 / 3881 Painting on construction place 1 x oil or acrylic paint System Outward appearance class Pu-3, service painting interval K / short (5-10 years) OPAQUE SYSTEM 2. Industrial priming 1 x Teknol 1881 / 2881 / 3881 Industrial topcoating 1 x Nordica Eko Painting on construction place 1 x Nordica Eko Housepaint System Outward appearance class Pu-2, service painting interval P / long (10-20 years) OPAQUE SYSTEM 3. - Industrial Priming 1 x Teknol 1881 / 2881 / Idustrial topcoat 2 x Nordica Eko Service painting interval P / long (10-20 years)

13 Transparent systems for claddings Examples of transparent systems according to RYL (Use /hazard/ class 3.2 according to EN 335-2) TRANSPARENT SYSTEM 1, fine sawed timber Industrial woodpreservative 1 x TEKNOL AQUA protection against blue stain, mildew and rot Industrial transparent primer 1 x TEKNOL 1888 tinted Topcoat at construction place 1xWOODEXTransparent,oil-/ waterbased System Outward appearance class 3, service painting interval L /short (2-5) TRANSPARENT SYSTEM 2, planed timber Industrial woodpreservative 1 x TEKNOL AQUA Industrial transparent topcoat 2 x NORDICA Service painting interval L / short (2-5 years) TRANSPARENT SYSTEM FOR LARCH Industrial transparent topcoat 1 x Teknoshield 4015 tinted

15 INDUSTRIAL CLADDING SYSTEMS FEATURES Industrial painting has to be done controlled way on to the dried wood. As a base product, alkyd primer is giving the best adhesion into the wood. Topcoats are often acryl based products giving good colour shade and gloss. Paint system is giving long maintenance properties and pursuits paint breathing properties, flexibility, adhesion, weather durability, colour and gloss stability. Last paint work is always proposed to be done at the house building site.

16 Note! Following issues after industrial painting During transportation and storing remember to protect the panels against machanical damages, dirt and high humidity Transportation and storing can not be done under heavy load (max. 2 packages on each other) Stacking paintfilms face to face is risky. The conditions during transportation and storing have big impact on the result. Package card gives instructions for transportation, storing and further treatments Cutted edges has to be painted at the construction place at least twice When doing further treatment or service painting, the most important thing is to take care of conditions (temperature degrees, humidity %)

17 References Teknos has over 20 years experience in industrial painting of claddings Today 17 milj m² is yearly primed with Teknol-products in Scandinavia and Central Europe 8 milj m² is topcoated with Teknos. Teknos is activily developing and promoting solutions to improve wooden construction systems Wood is enviromentfriendly and competitive construction material Primed claddings in Finland 90 %, Norway 60 %, Sweden 15 % (2015) Industrially primed + topcoated claddings in Finland 45 % (2015) Cladding business is very much related to interior panel and moulding business Wood as construction material is very competitive, but has to be used in right way.
