I think you might meet your liquid silicone rubber sometimes become thick, sometimes curing too slow, the hardener sometimes become crystallization, all these complaints make you upset and impact your company’s reputation.
Today we fixed it! Let’s discuss how we fix them.
1, Why the viscosity of liquid silicone become thick?
Some suppliers often change their raw materials supplier, who quote cheap, they purchase from who. but the performance of the raw materials produced by different suppliers exist a little difference, this makes even produced with a same formula, but the quality still have some difference, the new raw materials didn’t verified by time, new raw materials brings new uncertain risk.
a) We purchase the raw materials from a same supplier always, and keep formula won’t change, our formula has been approved by reiterative testing for many years, strength & other properties, and stability verified by different customers.
b) We use vacuum bag to pack the liquid rubber, no moisture and air can impact the rubber, this can get a longer shelf life and more stable quality.
2, Why is your hardener curing too fast or hardener crystallizing after several months of storage?
We’ve developed a new formula that prevents crystallization and ensures consistent curing time, even after long-term storage.
