SOS-726 STABILIZATION RESIN FAQ
WHAT IS SOS?
SOS-726, or SOS for short (pronounced like “sauce”) is a semi rigid heat cure Acrylate resin for stabilization of wood and other porous materials. SOS is specially formulated to penetrate deep in most woods, filling space inside and coating the exterior of cell walls with a polymer to reduce or prevent movement in the wood due to changes in moisture content. Additional benefits include bulking and hardening of soft wood.
DOES SOS NEED A VACUUM OR PRESSURE POT?
This form of stabilization works best with a vacuum. While it may be possible to soak wood until fully saturated, the results will not be as effective as those agained by use of a vacuum. Using a vacuum chamber removes trapped air and any remaining contained moisture in the wood and aids the penetration of cell walls by the resin. Pressure may be used, but this only aids to speed up the time after a vacuum when the wood is left to absorb the resin. At this time, there is not enough evidence to suggest any additional benefits to the use of pressure.
WHAT TEMPERATURE DOES SOS CURE?
SOS will begin setting up between 180-190 F. The target temperature is 190F for 10 minutes. This means enough time must be given for the very center of the wood to reach 190F. Wood is an insulator, so this takes a while. Large pieces need a very long time to cure fully. If you discover the resin has not fully cured, you can put it through another heat cycle. It’s not a one shot deal.
HOW DO I DISPOSE OF OLD OR CONTAMINATED RESIN?
Unused and uncured resin should be cured and disposed of with normal plastic trash. Although it is not known to be a serious risk to health or environment, it is best disposed of in volume as a solid. It is safe to clean your chamber and other items which have come in contact with SOS in a sink. Soap and water is all that is needed to clean up SOS.
CAN SOS BE REUSED?
Absolutely! It is important to use enough SOS to keep your wood fully submerged until you are confident you have full penetration. The remaining resin may be reused many times. This will introduce contaminants into the resin with every use. Oily woods in particular will release free-radicals into the resin. Enough contamination could cause the resin to excite and begin building polymer chains prematurely. Other sources of contamination could come from dirty, greasy or oily metal pieces or other foreign objects used to weigh down wood in the vacuum chamber. If you feel your SOS has become too contaminated to re-use, either dilute it with fresh resin or cure and dispose of with plastic rubbish.
WHAT SAFE HANDLING INSTRUCTIONS ARE THERE?
SOS should be treated with the respect and care of any chemical in your house. Do not eat or drink while using. Use only in a well ventilated area. Wash hands after use and avoid contact with skin, eyes and do not ingest. In some cases SOS can be an irritant. Sensitization is possible. If you get it in your eyes, flush with water immediately for 15 minutes including under the eyelids and remove contacts with plenty of water immediately. And as always if there is a question of your health or safety, seek medical advice. If you ingest SOS, rinse mouth with water and drink plenty of water afterwards then seek medical assistance without delay. With proper use, SOS is a safe and enjoyable addition to your woodworking and other creative projects.
Additionally, we recommend using suitable chemical resistant rubber gloves. Nitrile gloves are not well suited and may be affected by the resin.
CAN SOS BE USED TO DYE WOOD?
Yes. We recommend SOS Stabilization Dyes and Alumilite dyes in the following colors: Red, Orange, Yellow, Green, Blue, Ocean Blue, Violet (purple) and Brown. Some mixed results and success has been had with Alumilite Black as well. Any other dye is untested and we can not take any responsibility for wasted wood due to experimentation.
WHERE CAN I FIND THE (TDS/MSDS/SDS)?
