Matte Dipping Liquid Silicone for Shoelace Common Issues & Troubleshooting ⚠️
| Issue |
Root Cause |
Solution |
| Uneven surface gloss/bright spots |
Matting agent agglomeration, air bubbles, poor leveling |
Pre-disperse with dispersant, vacuum degas and filter; reduce viscosity, extend dripping time |
| Sticky surface/poor slip property |
Insufficient curing, insufficient slip agent dosage, excessive curing temperature |
Increase catalyst ratio, extend curing time; add more slip agent; control curing temperature ≤130℃ |
| Poor adhesion/peeling off |
Incomplete pre-treatment, incompatible silicone material |
Degrease + plasma activation; switch to self-adhesive matte LSR |
| Discoloration/yellowing |
Over-curing, temperature-sensitive color paste |
Lower temperature/shorten curing time; switch to high-temperature-resistant silicone color paste |
| Whitening/cracking after bending |
Excessively high hardness, insufficient crosslinking |
Select base silicone with Shore A 20–30; optimize catalyst ratio and curin |
