This cold-set collegen glue was recommended to us by furniture conservators as an alternative to hot-set animal glues. It is easy to apply, offering long open time and one minute tack, great strength and low toxicity. It may be sanded and is resistant to most solvents, and it has low water- resistance. A cured layer may be moistened to restore its original tack and bond characteristics. Squeeze bottles with pointed applicator tips are offered in 1 liter and 500 ml sizes, and a new 1/2 ounce (15ml) bottle with a small brush attached to its lid is now available.
