Common Sealing Problems ZDS Helps Solve

Sealing failure can lead to water leakage, dust entry, corrosion, electrical failure, product returns, and shorter product life.

Water Leakage

The adhesive may not match the joint design, material surface, or waterproof requirement.

Poor Adhesion

The surface may be difficult to bond, oily, coated, too smooth, or not properly treated.

Cracking or Peeling

The adhesive may be too hard or not flexible enough for vibration, movement, or temperature change.

Shrinkage After Curing

The sealing line may shrink and leave gaps if the formula does not match the application.

Slow Production Speed

The curing time may be too long for the assembly process.

Overflow or Poor Appearance

The adhesive may flow too much, create uneven edges, or affect the final product appearance.

ZDS helps customers reduce these risks through adhesive selection, viscosity adjustment, curing control, and custom formulation support.
