Multi-functional levelling additive for solvent borne
• Additive for primers or backer formulations
• Improved reactivity
• Rapid PU foam adhesion development
• Strengthens inter-coat adhesion of PU topcoats to primers
Dynoadd® F-802 is a multi-functional, adhesion promoting flow and levelling 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 levelling additive Dynoadd F-802 controls the surface tension of a coating thus eliminating surface defects such as orange peel, craters and pinholes.
