Product Description

High-Transparency Self-adhesive Liquid Silicone Rubber for Waterproof Sealing IOTA LSR 3050
Product Introduction:
IOTA LSR 3050 A/B is a high-transparency liquid silicone rubber with self-adhesive properties towards PC (Polycarbonate), while also exhibiting good mold release characteristics.
Main Features:
Two-component, 1:1 mixing ratio
Excellent mold release
Excellent transparency
Outstanding self-adhesion to PC
Fast thermal curing
Excellent mechanical properties
Typical Applications:
Swimming goggle sealing
Phone case overmolding
Smartwatch back cover sealing ring
Phone SIM tray sealing
Important Notes:
IOTA LSR 3050 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.
