Parts Desk Insights

Best Use Case: Use for electrical insulation and tight, conformable wrapping when you need the tape to hold closely to uneven surfaces for a clean, durable finish.

Common Issues: Common problems include poor adhesion if the surface is dirty/contaminated, gaps from insufficient overlap, and reduced performance when tape is stretched excessively or applied over moisture/contaminants. For best results, prep mating surfaces and wrap with proper overlap.
