An adhesive for repairs to pottery, wood, metal, ivory, glass and all porous substances except rubber. HMG Paraloid B72 is virtually colourless and tends to resist yellowing for a considerable length of time. Glass transition temperature of approx 40C. By not having instant grab, fragments can be easily re-adjusted with surplus adhesive removed with acetone, thereby making any joint virtually invisible. Slower drying time than AD1, making HMG B72 the popular choice for archaeological material on and off site. 14ml Tube.
