Water-Based Flocking Adhesive Selection by Substrate
Flocking adhesive selection changes when the substrate moves from paper or ABS to flexible PVC, PP, PE, metal or glass.
Use this note to
Key points
Identify substrate surface energy, contamination and pretreatment before choosing the adhesive route.
Flexible PVC needs plasticizer migration checks; PP and PE usually need activation or primer review.
Flock length, adhesive film thickness and open time affect final flock anchoring.
Separate the substrate families
Paper and foam raise penetration questions. ABS and many rigid plastics raise cleaning and release-agent questions. Flexible PVC adds plasticizer migration. PP and PE often need activation or primer review.
Metal parts need oil and oxide control, while automotive interior parts also need actual-part coverage, abrasion, odor and aging checks.
Compare routes with the same flocking process
Keep flock fiber, adhesive film thickness, open time, voltage and drying condition consistent when two adhesive routes are compared.
Use actual parts where corners, recesses or texture may affect coverage. Flat coupons can hide geometry-related failure.
