8 CHIMAR Hardeners Resin hardeners or curing agents: they accelerate the resin polymerisation Hardener technologies for all types of resins and wood panels Hardeners in either solid or liquid form Can be used either alone or in combination with conventional hardeners Eleftheria Athanassiadou, 8

9 CHIMAR Hardeners: Advantages Their application helps to reduce the press cycle thus increasing the productivity by up to 20% The board properties are improved enabling reduction of the resin level and thus reduction of the production cost In the case of MUF resins, CHIMAR special hardeners helped to improve the panels water resistance thus allowing the reduction of melamine content and therefore cost savings Eleftheria Athanassiadou, 9

10 CHIMAR Hardeners: Examples Hardeners H-200 H and H-143 H compared with NH4Cl in the case of UF resin Gel time, s UF resin NH4Cl H-200 H % hardener Hardeners H-200 H and H-143 H compared with NH4Cl in the case of MUF resin Gel time, s MUF resin NH4Cl H-200 H % hardener Eleftheria Athanassiadou, 10

11 CHIMAR Formaldehyde Scavengers CHIMAR scavengers are used to reduce the formaldehyde emissions during panel production as well as the emissions of finished panels Scavenger technologies for amino resin types (UF, UMF, MUF) Scavengers are tailor-made to satisfy the plant requirements and operating parameters (e.g. feedstocks,, final product requirements) First scavengers were commercially introduced on a global basis by CHIMAR at the end of the 1970 s Panels with formaldehyde emission at natural wood level were reported by CHIMAR already in 1993 Eleftheria Athanassiadou, 11

12 Formaldehyde Scavengers Action Synergistic action of CHIMAR amino resins and scavengers provides panels with desirable properties and formaldehyde emission as low as required Scavenger grades for achieving E1, half E1 (EPF-S S or IOS-MAT MAT-0003), E0 and even SE0 (F*** and F****,, JIS A 1460) Scavengers reduce formaldehyde emission permanently When applied, the scavengers induce no changes in board production process Eleftheria Athanassiadou, 12

16 CHIMAR Resin Extenders CHIMAR extenders are used to substitute part of the resin applied in panel production at no sacrifice of the panel properties, thus offering cost savings Extender technologies for amino and phenolic resin types Extenders are tailor-made to satisfy the plant requirements and operating parameters (e.g. feedstocks,, final product requirements) First extenders were commercially introduced on a global basis by CHIMAR at the end of the 1970 s Eleftheria Athanassiadou, 16

17 CHIMAR Extenders: Advantages Their application provides up to 10% savings on the binder cost When applied, the extenders induce no changes in board production process, therefore no additional investment is needed CHIMAR special grades with the extender-scavenger dual function are provided to reduce the process steps in board production Eleftheria Athanassiadou, 17

18 CHIMAR Fire Retardants CHIMAR provides technologies for fire retardant compositions effective in enhancing the panel fire resistance at desirable levels Advantages offered: Non-corrosive and halogen-free products High retention of properties - IB, MOR, swelling No deterioration of the properties with time No increase in formaldehyde emission, possible reduction of it The boardb surface is suitable even for veneering Eleftheria Athanassiadou, 18

19 CHIMAR PYRO-S S series Patent protected WO 02/ Application in MDF In liquid form, readily added in the blowline through a nozzle Dosing 10-15% 15% w/w based on dry fibres (depending on the plant operating parameters and the desired final product specifications) Can only be mixed with the glue in a static mixer Total pressing time may need to be increased up to 10% as compared to the standard MDF production Eleftheria Athanassiadou, 19

20 CHIMAR PYRO-SM series Application in PB In solid form Can be added in all board layers It is preferably added on the chips before the blender Dosing 15-20% w/w based on dry chips (depending on the plant operating parameters and the desired final product specifications) Use of a formaldehyde source may be needed eded to re- adjust the reduced formaldehyde of the system Eleftheria Athanassiadou, 20

21 Additives for Paper Impregnation CHIMAR provides technologies for the production of additives used in paper impregnation: Wetting agents Release agents Hardeners Eleftheria Athanassiadou, 21

22 Hardeners for Paper Impregnation Their application allows the reduction of the hardener level and thus reduction of the production cost They are easily applicable in conventional impregnation lines They provide impregnated paper and laminated boards with equal or even improved quality as compared to competitive hardeners Eleftheria Athanassiadou, 22

23 CHIMAR Recycling Process Patent protected WO 02/ CHIMAR recycling process allows the use e of up to 20% of waste boards (raw, laminated or veneered) in MDF manufacturing without deterioration of the panel mechanical properties and the production capacity Both in-house rejects as well as other waste panels can be recycled No major investments in equipment are required Eleftheria Athanassiadou, 23

24 CHIMAR Recycling Agents As part of this recycling process, a chemical composition (recycling agent) prepared according to CHIMAR technology is injected in the digester to promote fibre recycling Cost savingss may vary from plant to plant, depending on fuel self-sufficiency sufficiency and waste panel availability Eleftheria Athanassiadou, 24

25 CONCLUSION It is possible to meet the challenges of the global requirements for continuous improvement of the panel performance, using the integrated binder systems (resins and additives) offered by CHIMAR Eleftheria Athanassiadou, 25
