Q1: Why is enhanced adhesion necessary for plastic substrates, and how is it achieved?
A: Plastics like PP, PE, and untreated PET have low surface energy, causing standard coatings to peel or fail. This varnish uses specialized adhesion promoters and tailored resin chemistry that chemically bond to plastic surfaces, ensuring strong, durable attachment without delamination.

Q2: Which plastic applications benefit most from this varnish?
A: It is ideal for plastic packaging (food, cosmetic, retail), bottle labels, synthetic film printing, automotive interior trim, and electronic device surfaces where both visual appeal and long-term durability on plastic are required.

Q3: Are there specific surface preparation or curing requirements?
A: For optimal results, surface cleaning and/or corona/plasma treatment are recommended to increase substrate energy. The varnish can be applied via spray, roller, or curtain coater and typically air-dries or cures with mild heat. Full adhesion develops within the specified drying time—avoid over-coating or stacking before complete curing.
