Product Name: Silicone Resin
Item No.: SilibaseSRD-242A
Introduction:
China Offset of KR-242A silicone resins, SilibaseSRD-242A is cost-effective, versatile, and compatible with various additives, making it ideal for heating plates and resistor coatings.
Methyl silicone SilibaseSRD-242A is a solution-type coating for mica lamination. It is a product independently developed by our company. SilibaseSRD-242A can be diluted with solvents such as toluene, xylene, and ethanol. After hardening, it will not soften when exposed to heat and has excellent solvent resistance.
Products Benefits
This product forms high hardness film.
Less smoke generation when heated
This product has been mainly used as binders of inorganic materials (i.e. mica).
Product Features
As a leading China Analogue to KR-242A silicone resins, SilibaseSRD-242A offers high scorching residue (over 80% at 900°C) and enhanced flame retardancy for electronics and automotive applications.
Heat-resistant, electrical insulation, strong bonding, with our company's curing agent, good moisture-proof performance, high pass rate.
High scorching residue, more than 80% at 900℃. With the same amount of glue, the board output rate is increased by 2-3%.
Mica sheets formed using SilibaseSRD-242A have good electronic properties, smoke generation (smoke generation (0-6 seconds), and flame retardancy.

Packaging and Storage
This product is packaged in iron barrels or plastic barrels;
Stored in a dry, cool and ventilated place, avoid direct sunlight and rain, and isolate from fire and heat sources. Under this condition, the effective storage period is 6 months;
When transporting the product, it should be protected from sunlight, rain, inversion, open flames are strictly prohibited, and it should be transported as flammable goods.
Performance and Uses
China Equivalent KR-242A silicone resin outperforms conventional adhesives, increasing mica board output by 2-3% while maintaining low smoke generation and solvent resistance.
1. This product can be cured into a film when heated to 110-130℃ after adding appropriate curing agent. The film is transparent and can increase adhesion. It is used in the automotive, electronics and other industries. When used, appropriate additives or curing agents can be added as needed.
2. Compared with the adhesive used for mica lamination, it can be used as a heating plate to obtain a higher quality product. (Heating plate uses such as irons, hair dryers, toasters, microwave ovens, etc.)
3. It allows various heat-resistant pigments, flame retardants, low-melting-point glass raw materials, etc. to be evenly dispersed, and a coating for resistors that does not emit smoke and has a very low ignition point is obtained.
Application
Chinese Factory Supply of SilibaseSRD-242A silicone resin Similar to KR-242A.It's ensures superior heat resistance, strong bonding, and excellent electrical insulation for mica lamination and coatings .
2) Preparation of prepreg (pre-plasticization) |
Spray the adhesive solution on the integrated mica foil, so that the attached resin part is 8-10%, and heat it in a hot air drying oven at 100-130℃ for 5-10 minutes to allow the solvent part to disperse. If the heating time is too long at this time, the resin will gel and cannot be formed. If the heating time is too short, the solvent will remain, resulting in low strength or poor contact.
