Instructions for use

1. XJY 301-4 Silicone Pressure Sensitive Adhesive is recommended to use the catalyst Bis(2,4-dichlorobenzoyl) peroxide, BPO (benzoyl peroxide), and the catalyst usage amount is 2-3%;

2. The temperature of the solvent volatilization section is kept below 120°C to ensure the lowest control of catalyst decomposition and complete solvent volatilization, otherwise the tape will produce pores and affect the performance of the adhesive;

3. The catalyst preparation concentration is 10%. After preparation, use it as soon as possible, otherwise, the solvent will consume the catalyst and affect the catalytic effect;

4. During curing, the curing temperature can be appropriately increased to ensure that the catalyst is completely decomposed, otherwise, the tape will easily produce white gel-like substances. If BPO is used as the catalyst, the decomposition of the incomplete catalyst will generate a small amount of carbon dioxide gas, forming pores, and affect the performance of the tape.




XJY-301-4 SPSA can provide the 200KG inner coated iron drum. If you have special requirements, you can negotiate and customize.
