Dynoadd® F-802 is a multi-functional, adhesion-promoting flow and leveling agent. Dynoadd® F-802 has similar properties to Dynoadd® F-800 but with considerably higher reactivity enabling immediate adhesion between the coated surface and the -NCO cured formulation. The novel surface active Dynoadd® F-802 polymer modifies coating surfaces in such a way that adhesion to -NCO curing formulations such as foam, adhesives, or coatings is considerably improved. As an effective flow and leveling additive Dynoadd® F-802 controls the surface tension of a coating thus eliminating surface defects such as orange peel, craters, and pinholes. The properties of Dynoadd® F-802 make it ideal for formulating backer coatings which have good foam adhesion without the use of additional adhesion resins. The adhesion promoting properties are maintained even after repeated curing.
