How to make mold?
Please weight 2 Part A and 1 part B in a clean container.Thoroughly stir Part A before use, as filler separation may occur upon prolonged storage. Mixing Part A and Part B evenly until part B completely dispersed in the part A. Hand or mechanical mixing can be used,but do not for an extended period of time or allow the temperature to exceed 35°C. Mix suitably small quantities to ensure thorough mixing of part A and part B.
It is strongly recommended that entrapped air be removed in a vacuum chamber,allowing the mix to completely expand and then collapse. After a further 1-2 mins under vacuum,the mix should be inspected and can be used if free of air bubbles. A volume increase of 3-5 times will occur on vacuum de-airing the mixture. So a suitably large container should be chosen.
Pouring the mixture and curing
Pour the mixed Part A and part B as soon as possible onto the original,avoiding air entrapment.The catalyzed material will cure to a flexible rubber within 16 hours(or faster by different mixing ratio or room temperature).
Storage:
When stored at or below 30°C in the original unopened containers,Polyurethane rubber have a usable life of 12 months.from the date of production.
