I purchased this to make bora-care insect repellant for lumber that had been recently milled. Only used 1 gallon. I can also sell Borax and Boric Acid if interested.
Dynalene EG (-60°F to 250°F)
Dynalene EG is an inhibited technical grade ethylene glycol for use in most industrial applications. It is blended with Dynalene PE-1 inhibitor for pH stability and superior corrosion protection for steel, copper, brass and other metals.
Other Applications:
--HVAC
--Process Cooling/Heating
--Industrial Processes
--Radiant Heating Systems
--Ice Melting
--Ice Rink
HOW TO MAKE BORA-CARE :
Bora Care is a 40% solution of sodium octaborate in ethylene glycol; 27% borate content.
All percentages are by weight.
60% borax - 40% boric acid (by weight) gives the maximum solubility of borates in water.
A gallon of glycol weighs 9.3 lbs (confirmed) so that means:
1 gallon glycol (9.3 lbs) + 3.72 lbs Borax, + 2.48 lbs boric acid.
However, an internet formula has it different: (Possibly because some bound water in the borax gets boiled off) THAT formula says: 1 gallon glycol, 4.5 lbs Borax, 3.5 lbs boric acid.
To make a stable solution you mix the ingredients and heat till boiling gently.
Boil off water until a candy thermometer shows 260°F.
This removes most of the water of crystallization in the borax.
WARNING: If you use ethylene for a glycol do not breath the fumes as you boil the mixture !!!
This solution has a borate content of 26%. It is stable at 40°F
Again, this is the same solution that they sell online. It must be diluted 50 / 50 with water, just before application.
HOW TO APPLY BORA-CARE :
Boracare can be sprayed or brushed on.
It must be diluted 50 / 50 with water, just before application.
## After diluting it, you must use it within 24 hrs !!!!
You must coat EVERY bit of exposed surface on your lumber.
Boracare needs to remain liquid as long as possible, so as to get deep into the lumber. Therefore, it’s best to apply it when ambient temperatures are not extremely high.
note: Wetting dry wood before applying BoraCare is not recommended.
Once the bare wood becomes dry to the touch, it can be finished or glued.
It typically dries clear, however if over-applied it can leave a white borate residue on the surface. This can simply be washed off with water and the surface allowed to dry. Unlike Timbor, Bora-Care rarely deposits any residue after the first day or so, due to the binding power of the glycol.
Once applied, Boracare lasts FOREVER. You never have to re-apply it.
COVERAGE:
You will be making the same solution that they sell online. Both must be diluted 50 / 50 with water, just before application.
1 gallon of pre-diluted Bora Care will treat 800 BF.
( One gallon becomes 2 gallons before spraying, still covering 800 BF.)
