1. Base Material Properties
The Crown DS513 Double-sided Tape uses a 0.08mm specialty cotton paper substrate. It weighs 65g/㎡.
The longitudinal tensile strength is 90N/cm or higher. The transverse strength is 80N/cm or higher.
The elongation rate is 6% or less. This keeps the material stable during processing.
The substrate can handle temperatures up to 160°C for 30 minutes.
2. Adhesion
180° peel strength (stainless steel): 22±2N/25mm
Adhesion:>72h (1kg load, 23℃)
Initial adhesion: No.10 steel ball (inclined ball rolling method)
Minimum peel strength of ABS/PC material ≥12N/25mm
3. Processing Characteristics
Supports precision die-cutting with a minimum die-cutting contour of 1.5mm
Release force: 8-12N/25mm, suitable for automated production lines
The substrate elongation rate is stable, with a cutting accuracy of ±0.1mm.
4. Environmental Adaptability
Operating temperature range: -30℃ to 100℃
Damp heat resistance: After 500 hours at 85℃/85%RH, the bonding strength retention rate remains over 85%
Good corrosion resistance was obtained through 48-hour salt spray test
5. Security Certification
SGS testing confirms compliance with RoHS/REACH standards
VOC emissions <3μg/g (tested at 40℃)
1. Substrate Structure Characteristics
I. Substrate pretreatment process
Raw material testing: Conduct tensile strength test on 0.08mm cotton paper substrate (≥90N/cm in longitudinal direction, ≥80N/cm in transverse direction)
Corona treatment: The substrate surface tension is elevated to 52-54 dyn/cm using a corona treatment device.
Preheating and setting: The substrate undergoes stabilization treatment on a 85℃ preheating roller to eliminate internal stresses.
2. Adhesive Preparation System
Raw material ratio: Acrylate monomer and tackifier resin are pre-mixed in a specific proportion
Reactor synthesis: Conduct a 5-hour polymerization reaction at a constant temperature of 88℃
Viscosity control: Use a rotational viscometer to ensure the adhesive viscosity is within the range of 3800±500 cps.
3. Precision Coating Process
Double-sided coating: Utilizes a micro-embossed coating head with a speed of 18-28m/min
Thickness control: Both sides of the adhesive layer are 0.06mm thick, with a total thickness of 0.20±0.02mm
Drying system: Four-stage drying oven with temperature gradient set at 65℃/85℃/105℃/80℃
4. Composite Machining Process
Release film lamination: The Crown DS513 Double-sided Tape is joined with a silicone oil release film. The release force is 8-12g/in.
Maturation: The material stays in a 45℃ chamber for 36 hours. This completes the cross-linking reaction.
Quality Control: An online system checks coating thickness all the time. The tolerance is ±2.5%.
5. Post-Processing Flow
Cutting process: A high-precision circular blade cutter is used. The cutting accuracy is ±0.15mm.
Reel control: The rewinding system keeps tension steady. The tension range is 2-4N.
Packaging environment: Packaging is done in a clean area. Temperature is 23±2℃. Humidity is 50±5%RH.
6. Quality Control System
Each product roll undergoes initial adhesion (10# steel ball) and adhesion retention (>72h) testing.
Each batch undergoes high-low temperature cycling tests (-30℃ to 100℃).
Send samples regularly for third-party testing to ensure compliance with international standards
