use on hands or skin) but caution should be observed and followed by a thorough clean water
rinse.
Since Resorcinol is difficult to impossible to remove once cured, cleanliness of the working area
and personal cleanliness of the operators while mixing and using the adhesive is required, and
especially to prevent dermatitis and respiratory irritations. The wearing of face masks, rubber
gloves and other protective clothing is strongly recommended.
Performance
Coverage.
The coverage of Weldwood Resorcinol Glue depends greatly upon the wood texture,
moisture contend and the glue line thickness. Coverage of between 100 and 150 square feet per
gallon of glue line may be expected depending upon the precision of technique.
Cure Rate.
Resorcinol reaches ultimate strength and complete waterproofness after room
temperature aging for one week. Therefore, no test for joint strength, waterproofness or durability
should be performed until after this curing period.
Resorcinol glued stock may be lightly machined upon release from pressure, but heavy machining,
shaping or undue rough handling should be postponed until after a tempering period of from 12 to
24 hours above 70°F.
Bond Strength.
The bond strength of properly prepared glue joints with Weldwood Waterproof
Resorcinol Glue are usually in excess of the strength of the wood bonded.
When tested on hard maple in block shear (re: ASTM D905) Resorcinol bonds have a
compression shear strength in excess of 2,800 psi.
Heat and Water Resistance.
Three ply, yellow birch, 3/16-inch plywood laminates boiled in
water for 3 hours and cooled in water for 1/2 hour still have an average tension shear strength of
at least 400 psi.
Durability.
Weldwood Resorcinol glued joints, when properly prepared per manufacturer’s
recommendations and sound, standard commercial practices, are among the most durable bonds
available for wood, and usually in excess of the substrate life.
Storage and Handling
Temperature.
Weldwood Waterproof Resorcinol Glue should be stored at temperatures of 70°F
or below for best storage stability. Storage at temperatures above 70°F may reduce expected shelf
life due to solvent and catalyst evaporation.
If the liquid resin becomes frozen from prolonged storage or shipping at low temperatures, the
adhesive must be allowed to return to room temperatures and stirred before use.
Shelf Life.
Weldwood Resorcinol Glue is packaged in two containers per unit, in all sizes; the
liquid resin is in one and the powdered catalyst in the other. These components remain usable for
a reasonable length of time under normal storage condition in the original tightly closed
containers. These containers should be kept tightly closed as much as possible to prevent solvent
loss.
