Applications
Baycoll® AD 5027 can be combined with various Desmodur® products to formulate adhesives for many different materials, e.g. wood, metal and plastic. Baycoll® AD 5027 is suitable for use in the formulation of reactive adhesives. On account of its high crystallinity, Baycoll® AD 5027 is particularly suitable for the formulation of reactive polyurethane melt adhesives with high green strength.Baycoll® AD 5027 can be thinned with solvents such as esters, ketones and aromatics. Only PU grade solvents should be used (< 0.05 % by wt. water).
Form supplied
