  • Using Manual Of Heat Curing Silicone Optical Adhesive BTL-5123AB

    1. Surface treatment


    All sizing interfaces must be cleaned. During use and storage, it must be ensured that there is no catalyst toxic substances such as phosphorus (P), sulfur (s), nitrogen (n), organic tin (SN), water, polyurethane and so on, so as to avoid curing hindrance and deterioration.


    2. Mix


    Component A is a cross-linking agent B contains a catalyst. The catalyst can make a gel containing crosslinking agent gel. Therefore, when using a scraper and other operation tools, we must avoid mixing with this component.


    3. Solidify


    The curing time of liquid silicone rubber is closely related to curing temperature and colloid thickness. The conventional mixing ratio of a / B is 1:1. The proportion deviation has a certain impact on the colloidal hardness. Increasing group A will improve the hardness of the cured product.

  • Precautions Of Heat Curing Silicone Optical Adhesive BTL-5123AB

    1. Before bonding, it is necessary to test the matching of glue with LCM and TP;

    2. After the bonding is good and cured according to the normal process, it needs to be placed at 25 ℃ for 7 days before environmental testing.
