Key Advantages & Features

01: Distinctive Visual Identity
Innovative light blue transparent appearance provides not only aesthetics but also a unique visual identifier for your products. In potting/encapsulation applications, the light blue color aids quick identification and differentiation between batches or models.

02: Efficient Curing Performance
Optimized formulation achieves surface dry in 8-12 hrs and full cure in 24-36 hrs, significantly shortening production cycles. Maintains high hardness (Shore D 82) and excellent heat resistance (HDT 60°C).

03: Excellent Processing Properties
Moderate mixed viscosity (500±200 mPa·s) with excellent self-debubbling and leveling ensures bubble-free filling of complex molds and mirror-smooth surface finish.

Usage Guide & Steps

Step 1: Precise Measurement

• Place a clean mixing cup on the digital scale and press the "Tare/Zero" button.
• Pour Part A into the cup until reaching the target weight (e.g., 20g).
• Press "Tare" to zero the scale, then pour Part B to the corresponding weight (e.g., 10g).
  

➤ Key Tip: Always maintain the A:B = 2:1 weight ratio.

Step 2: Thorough Mixing

• Using a stirring stick, stir at a constant speed in one direction gently.
  
• Continue stirring for 2-3 minutes until the mixture becomes uniformly transparent and string-free.
  

➤ Key Tip: Scrape the cup walls and bottom during stirring to ensure no unmixed areas.

Step 3: Resting & De-bubbling

• Let the mixed resin rest for 3-5 minutes to allow bubbles to rise and burst naturally.
  
• Observe the resin surface and proceed only after most bubbles have disappeared.
  

Step 4: Creative Crafting
Option A: In-mold Coloring (Ink Wash Effect)

• Gently pour the de-bubbled resin into the mold.
  
• Dip a toothpick into a tiny amount of pigment and lightly touch the resin surface.
  
• Allow the pigment to diffuse naturally, creating unique ink wash patterns.

Option B: Pre-mix Coloring

• Add pigments, glitters, or other decorations to the de-bubbled resin.
  
• Stir gently for 30-60 seconds until evenly distributed.
  
• Pour the mixture slowly into the mold, gently tapping to remove remaining bubbles.

Step 5: Curing & Quality Verification
Room Temperature Curing Guide (15-25°C)
Phase 1: Surface Dry Check (8-12 hours)

• After 8 hours, test edges with the back of a clean finger.
  
• Surface should feel dry and non-tacky, no fingerprint residue with light pressure.
  
• Mild handling or surface cleaning is acceptable at this stage.
  

Phase 2: Full Cure Completion (24-36 hours)

• After 24 hours, conduct a comprehensive hardness test.
  
• Light nail scratch should leave no marks or dents.
  
• Product is ready for normal use, processing, or polishing.

Safety, Handling & Storage Guidelines
1. For Safe Operation & Mixing

• Safety First: Operate in a well-ventilated area, away from ignition sources. Avoid skin and eye contact.
  
• Mix as Needed: Estimate quantity based on the 40-minute pot life to avoid waste.
  
• Adapt to Conditions: Preheat Component A if temperature <15°C; use heat-assisted curing if humidity >85% to prevent surface whitening.
  
• Safe Keeping: Keep out of reach of children.

2.Storage And Shelf Life

• Storage Conditions: Store in a cool, dry place below 25°C (77°F). Keep away from direct sunlight, heat sources, and humid environments.
  
• Packaging & Stability: The product has a shelf life of 6 months from the date of manufacture when stored unopened in its original container under recommended conditions. Once opened, reseal tightly and use as soon as possible. Do not leave exposed to air for extended periods.
