Bonding Agent 2005 is a high performance one component aromatic polyisocyanurate bonding agent used to improve the adhesion of PVC plastisol inks and coatings to substrates made of polyester, polyamide or aramid fibers.
The bond strength of a coating is wholly dependent on the composition of the base coat. For this reason, the section below deals with the base coat only. 2-6 % Bonding Agent 2005 is the quantity recommended for PVC base coat plastisols. Under standardized conditions, the addition of 4 % by wt. Bonding Agent 2005 led to average bond strength values of >250 N/5 cm for polyester fabric and >260 N/5 cm for polyamide fabric. Bonding Agent 2005 is a moisture-sensitive reactive system. The bonding agent should not be mixed into the PVC base coat plastisol until shortly before coating.
