Thermal conductive products
IOTA LSR 3760 is a platinum-catalyzed product, with the platinum catalyst contained in Component A. Strict attention must be paid during use to avoid catalyst poisoning.
Only Component A and Component B of the same batch number can be mixed and used together.
To ensure the optimal fluidity and uniformity of the material, the material must be fully stirred evenly before being transferred to the container, so that the fillers that may settle during storage are uniformly dispersed.

When stored in unopened drums at a temperature below 23℃, the shelf life is 12 months. The best before date is marked on the label of each product's outer packaging.
This material is not necessarily unusable beyond the shelf life; in such cases, performance tests for relevant indicators must be conducted to ensure quality.
