Product description

Stabilizing resin Jatapol WR90N - supplied in an unactivated state, the activator is supplied separately in a can. Before use, pour the activator into the resin canister, shake well and leave for min. 3 hours to dissolve. Then shake and mix again the resin is ready to use. The lifetime of the activated resin is min. 12 months, provided the storage temperature is up to max. 20°C.

Professional wood stabilization

A block of wood with a beautiful pattern conjured up by wood decay fungi - too bad it can't be used on the knife I'm currently making... Error! It can be used, and the spell that enables it is called stabilization!

JATAPOL WR90N is almost odorless, store at a temperature of up to 20°C. Curing of the resin takes place at an elevated temperature of 80-85°C either in an oven or in hot water for a period of min. 120 minutes. It is important to observe the temperature, if the temperature is lower than 80°C, polymerization will not occur, if it is higher, the boiling point of the resin will be exceeded. It is best to let the stabilization chamber (oven) heat up to a temperature of 80°C and then insert the aluminum foil-wrapped logs into the chamber. This will allow polymerization to take place in the shortest possible time. Furthermore, it is necessary to maintain the temperature in the range of approx. 80-85°C, in order to maintain the temperature in this range, it is necessary to take into account the increase in temperature that occurs during polymerization (a chemical reaction that generates heat) - so it is best to have one more sensor directly at the stabilized log (connect in series with the sensor that monitors the temperature inside the furnace, one more sensor, and then attach it directly to the stabilized block.) It is essential to keep the temperature of the block in the range of 80-85°C.

For stabilization in small batches, it is sufficient to harden the stabilized logs in hot water - use a thermometer to monitor the temperature of approx. 80-85 °C, once the water is heated to this temperature, the logs are stuffed with WR90N (either vacuum the logs in a plastic bag in a food bag, or it is enough wrap it properly in stretch food foil) put it in hot water, and keep the temperature at approx. 85°C. The advantage of curing in water is that as soon as a chemical reaction occurs in the block and heat is generated, the water immediately removes the excess heat, whereas in the air chamber you must have a sensor directly on the block so that the furnace heating is turned off immediately after the temperature rises, because the air it conducts heat worse than water, so stabilization in a hot air furnace is very demanding on temperature regulation.

At this temperature, the resin will polymerize, after cooling, the block can be sanded and polished to a high shine.

Sample video stabilization

V tomto videu můžete vidět postup při stabilizaci dřevěných špalíků pomocí pryskyřice Jatapol WR90N.

Návod jak stabilizovat v domácích podmínkách:

Dřevěný špalík musí být vysušen na méně jak 8% vlhkosti. Vysušený špalík se umístí do vakuové komory a ponoří se zcela do JATAPOL WR90N pryskyřice (špalík je nutné zatížit , aby byl celý ponořený v pryskyřici. Vyvakuujeme vzduch z vakuové komory a necháme v komoře tak dlouho, dokud ze špalíku nepřestanou unikat vzduchové bublinky (cca 1hod. - záleží na druhu dřeva). Po té uvolníme vakuum a necháme špalíky ponořené v pryskyřici ještě min. 30 minut. V tuto chvíli dochází k pronikání pryskyřice do špalíku. Tento postup můžeme několikrát opakovat. Jakmile je špalík dostatečně prosycen pryskyřicí, zabalíme špalík do alobalu a vložíme na cca 2 hodiny do předehřáté trouby, nebo špalíky vytvrdíme v horké vodě - viz návody výše.  Pozor, klasické trouby nemají přesné měření, je nutné teplotu 85°C dodržet.

Při této teplotě dojde k polymerizaci pryskyřice, po vychladnutí lze špalík obrousit a vyleštit do vysokého lesku.

Výhody WR90N

  • Zbytky pryskyřice je možné omýt vodou a mýdlem. Po vytvrzení se stabilizované dřevo velmi snadno opracovává a leští.
  • JATAPOL WR90N lze použít opakovaně (výhoda oproti EPOXY pryskyřici), špalíky ponoříte do pryskyřice, ve vakuové komoře provedete díky velmi nízké viskozitě proniknutí do celého průřezu špalíku, špalíky z pryskyřice vyjmete, a zbylou pryskyřice můžete použít příště. Průměrně jeden špalík o rozměrech 30x40x125mm pojme cca 100g pryskyřice, takže z 1litru uděláte cca 10špalíků.

Profesionální stabilizace se provádí ve vakuotlakových komorách, za pomocí vakua a velmi vysokého tlaku. V domácích podmínkách za pomocí vývěvy lze také úspěšně stabilizovat měkčí dřeviny, dřeviny napadené hnilobou apod..
