SilGrip™ PSA630 : Ultra-high initial tack silicone pressure sensitive adhesive
SilGrip™ PSA630 (hereinafter referred to as PSA630) is a unique BPO catalytic condensation curing silicone pressure sensitive adhesive launched by Momentive in recent years. It has excellent initial adhesion performance and is one of the products with the highest initial adhesion performance on the market. In addition, PSA630 also has excellent high temperature resistance. Momentive's advanced production process and quality management ensure that the product performance is highly consistent between different batches.
Main Features
High initial adhesion: The initial adhesion performance test result of PSA630 exceeds the No. 32 rolling ball test.
Excellent high temperature resistance: After SAFT (Superior Adhesion Failure Temperature) test, no residue was left after hot and cold tear test at 260°C for half an hour.
Strong peel strength: Under the conditions of 25μm PET substrate and 50μm adhesive thickness, the peel strength can reach about 850g.
Soft adhesive surface: PSA630 avoids the problem of excessive unwinding force or whitening of the adhesive surface during unwinding, and can be used normally even in winter temperatures in East and North China.
Basic parameters
Appearance: Transparent liquid, straw yellow
Solid content: 61%-64%
Typical viscosity: 95000 cps
Solvent: Toluene
Recommended applications
PSA630 is suitable for various tape products, including Teflon tape, PI tape and PET tape.
Frequently asked questions
Curing process of pressure sensitive adhesive:
The curing process of conventional silicone pressure-sensitive adhesives is divided into two stages: solvent evaporation and adhesive layer curing.
The temperature during the solvent evaporation phase should not exceed 93°C to prevent premature curing. Recommended temperature range: 83-90°C, typical curing time is 2 minutes at 90°C.
The recommended temperature range for glue layer curing is 165°C-204°C, and the typical curing time is 2 minutes at 165°C.
Primer recommendation:
Consider using the Momentive SS4191A system as a primer. It has good compatibility with various Momentive silicone pressure-sensitive adhesives, stable performance, and low unit consumption. For more information, please contact the relevant sales team of Haiyi.
Catalyst recommendations and dosage:
PSA630 can be cured using benzoyl peroxide (BPO) or 2,4-dichlorobenzoyl peroxide (BPO-24).
The recommended dosage range is 1-4% (by dry weight). The actual dosage should be evaluated and verified based on production line conditions and performance requirements.
