Usage Guide & Steps
Manual Dispensing Process:
1.Environment Preparation: Maintain 15-25°C, <70% RH; condition materials for 24h before use.
2.Substrate Pre-treatment: Preheat substrates (e.g., PVC, plastic labels) at 60°C to remove moisture; fix on level surface.
3.Surface Cleaning: Thoroughly remove dust and oils.
4.Precise Mixing: Weigh Parts A and B at 1:1 ratio, mix until homogeneous.
5.Vacuum Degassing: Degas at -0.1MPa until bubble-free.
6.Even Coating: Transfer degassed resin to clean syringe; apply evenly (typical thickness: 2mm).
7.Surface Inspection: Inspect within 5 mins; address bubbles/dust.
8.Curing: Cure at 60-80°C for 2-3.5h or at room temperature.
Mechanical Dispensing Process:
1.Material Conditioning: Condition sealed containers at 15-25°C, <70% RH for >96h.
2.System Setup: Install suction pumps; let stand for 24h.
3.Substrate Preparation: Fix substrates on flat surface.
4.System Flushing: Flush static mixer and dispense head with dichloromethane or ethyl acetate.
5.System Purging: Dispense to purge air from lines.
6.Even Dispensing: Dispense mixed resin evenly onto surface.
7.Spreading & Debubbling: Spread resin with needle; remove residual bubbles.
8.Heat Curing: Transfer to 60°C oven; cure completely in 2-4h.

FAQ:
Q1:What's the main difference between manual and mechanical dispensing formulas?
A1: The manual formula offers longer pot life (15 mins) for detailed hand work; the mechanical formula cures faster for automated batch production. Both deliver identical cured properties.
Q2: What should be noted when mixing quantities exceed 100g?
A2: Larger mix quantities reduce pot life. For large batches, using a mechanical dispensing system with strict temperature and mixing time control is recommended.
Q3: Why is Part B's shelf life shorter than Part A's?
A3: Part B (isocyanate) is more moisture-sensitive and can react with airborne humidity, hence its shorter shelf life (3 months). Reseal immediately after use and store in a dry environment.
