Sealant: Pressure Resistance Up to 15 bar

Component Specifications

Definition

A high-performance industrial sealant specifically formulated for precision percussion primer cups in mechanical systems. This material creates durable, flexible seals that maintain integrity under dynamic pressure conditions, temperature variations, and mechanical stress. It prevents leakage of gases and fluids while protecting sensitive components from environmental contaminants and corrosion.

Working Principle

The sealant functions through controlled curing mechanisms (typically chemical or moisture-curing) that transform liquid or paste formulations into elastomeric solids. It fills microscopic surface imperfections and creates molecular adhesion to substrate materials, forming a continuous barrier that accommodates thermal expansion, vibration, and pressure fluctuations while maintaining sealing integrity.

Frequently Asked Questions

What is the maximum pressure this sealant can withstand?

This sealant is rated for continuous service up to 15 bar (approximately 217 psi) with short-term peaks up to 20 bar.

How long does the sealant take to fully cure?

Full cure is achieved in 24 hours at standard conditions (23°C, 50% relative humidity), with handling strength typically reached within 2-4 hours.

Can this sealant be used in food processing equipment?

No, this specific formulation is not FDA-compliant. For food applications, specialized food-grade sealants with appropriate certifications should be used.

What surface preparation is required before application?

Surfaces must be clean, dry, and free of oil, grease, and loose particles. Light abrasion and solvent cleaning (isopropyl alcohol) are recommended for optimal adhesion.
