Product Features & Advantages
Ultra-low linear shrinkage ensures stable size and high precision of auto parts molds, with no deformation during curing. Deep curing function breaks the thickness limit, suitable for large and thick automobile molds such as tires and hoods. Excellent high and low temperature resistance adapts to various casting materials and complex production environments. Strong chemical corrosion resistance prolongs mold service life and supports repeated molding cycles. High fluidity makes pouring and coating easier, fully restoring complex lines and fine details of auto parts. Non-toxic and odorless formula ensures safe and environmentally friendly production.
How to Use the Product
Step 2: Weigh Part A and Part B in 1:1 ratio, stir evenly for 2 to 3 minutes until fully mixed.
Step 3: Conduct vacuum defoaming for 1 to 2 minutes to remove air bubbles and improve mold smoothness.
Step 4: Pour or brush the mixed silicone on the auto part prototype, covering all surface details completely.
Step 5: Cure at 25℃ room temperature for 4 to 6 hours, or heat to speed up curing; demold gently after full curing.
Step 6: Conduct a small sample test before formal production to verify mold precision and usability.
Application Scenarios
