Important Notes:
IOTA LSR 3061 A/B is a product cured using a platinum catalyst. The platinum catalyst is in Component A. Strict attention must be paid during use to avoid catalyst poisoning.
Only Component A and Component B from the same batch number should be mixed and used together.
To ensure optimal fluidity and homogeneity, the material must be stirred thoroughly before being transferred to containers to uniformly disperse any fillers that may have settled during storage.

Storage and Shelf Life:
When stored unopened below 23°C, the shelf life is 12 months. The best use-by date is marked on the label of each product's external packaging.
Material exceeding the shelf life is not necessarily unusable. In such cases, performance tests for relevant parameters must be conducted to ensure quality.
