Curing
IOTA-26 series liquid silicone rubber will quickly solidify at high temperature.Curing time depends on thickness and curing temperature used.Contact with certain materials, such as amines, sulphur and tin compounds, inhibits curing.
Applicaiton method
Mix and expel air
Components A and B have been filtered and air removed for use as matching lot Numbers when supplied.Mix part A and part B in A 1:1 ratio.It is strongly recommended to use metering and mixing equipment of conveying, metering and mixing two components without infiltration of air.If air bubbles are introduced during the mixing process, a vacuum device must be used to completely remove the air.
Storage
Products should be preserved in 32 ° C or lower temperature in the unopened original container.The storage life of this product is 9 months, and it can be used after passing the re-inspection.
Available time
After A and part B mixed, mixture at 25 ° C is valid for 48 hours.
Package
55 gallon steel drum (net weight 200kg) or 20L straight plastic drum (net weight 20kg).
