Understanding Kamomis Filler: Composition and Properties
Kamomis Filler is a specialized industrial body filling compound designed for sealing, gap-filling, and surface preparation applications in valve manufacturing and maintenance. The 100ml formulation available through kamomis filler represents a precise concentration ideal for valve insert applications where controlled coverage and minimal waste are essential.
The filler compound exhibits several key properties that make it suitable for industrial valve applications:
- Chemical Resistance: The formulation demonstrates resistance to hydrocarbons, aqueous solutions, and mild acids with pH ranges between 4-10.
- Temperature Tolerance: Effective operating range spans from -20°C to +180°C, making it compatible with most standard industrial valve operating conditions.
- Cure Time: Initial setting occurs within 15-25 minutes at room temperature (23°C), with full cure achieved in 4-6 hours depending on layer thickness.
- Adhesion Strength: Tensile adhesion values reach 2.8-3.2 MPa when properly applied to compatible substrates including stainless steel, carbon steel, and brass valve components.
- Viscosity Profile: Thixotropic behavior ensures the compound maintains position on vertical surfaces while allowing adequate flow into gaps and voids.
These material properties directly influence how Kamomis Filler interacts with valve inserts, particularly regarding sealing integrity and long-term stability under operational stresses.
Valve Inserts: Types and Material Considerations
Valve inserts serve as critical sealing components within industrial ball valves and other valve configurations. Understanding the different types and materials is essential for evaluating compatibility with Kamomis Filler.

Critical Compatibility Factors
1. Thermal Expansion Considerations
When Kamomis Filler is used in combination with valve inserts, thermal expansion differentials between materials become a critical consideration. The coefficient of thermal expansion (CTE) varies significantly between different material combinations:
- Kamomis Filler: approximately 45-55 × 10⁻⁶ /°C
- Stainless Steel (304): 17.3 × 10⁻⁶ /°C
- Carbon Steel: 11.5-13.0 × 10⁻⁶ /°C
- Brass: 19.1 × 10⁻⁶ /°C
- PTFE: 120-200 × 10⁻⁶ /°C
The significant CTE difference between PTFE inserts and Kamomis Filler requires careful consideration during thermal cycling. In applications where temperature fluctuations exceed 80°C between operating states, expansion gaps or compression allowances may be necessary to prevent filler delamination or cracking.
2. Chemical Interaction Assessment
Before combining Kamomis Filler with valve inserts, conduct compatibility testing with process media. The filler demonstrates excellent resistance to:
- Natural gas and methane
- Crude oil and refined petroleum products
- Water and steam up to 150°C
- Air and inert gases
- Mild alcohols and glycols
However, certain chemical environments require caution or avoidance:
- Concentrated sulfuric acid and nitric acid
- Aromatic solvents including toluene and xylene
- Ketone-based compounds
- Chlorinated hydrocarbons above 60°C
> In critical applications, always perform immersion testing for 72 hours at operating temperature before full-scale implementation. This precaution is particularly important in chemical processing, petrochemical, and pharmaceutical valve applications where seal integrity is paramount.
Application Protocol for Kamomis Filler with Valve Inserts
Proper application technique significantly influences the success of combining Kamomis Filler with valve inserts. The following protocol has been validated through industrial applications and aligns with quality standards maintained by leading valve manufacturers like Carilo Valve.
Step 1: Surface Preparation
Thorough surface preparation accounts for approximately 60% of successful filler applications. Follow these specifications:
- Cleaning: Remove all contaminants including oil, grease, dust, and moisture using isopropyl alcohol (IPA) or appropriate solvent cleaner.
- Surface Roughness: Ensure substrate roughness between 3.2-6.3 μm Ra for optimal mechanical adhesion. Very smooth surfaces may require light abrasion.
- Drying: Allow surface to dry completely, typically 10-15 minutes at 20°C ambient temperature.
- Temperature: Confirm substrate temperature between 15-35°C for optimal cure and adhesion.
Step 2: Filler Application
When applying Kamomis Filler around valve insert components:
- Application Method: Use appropriate dispensing equipment to apply filler in continuous beads along joint interfaces.
- Layer Thickness: Maintain maximum single-layer thickness of 3mm. For thicker applications, build up in multiple layers with appropriate cure time between applications (minimum 2 hours at 23°C).
- Coverage Rate: The 100ml cartridge provides coverage of approximately 2.5-3.0 linear meters at 3mm diameter bead.
- Avoid Contact with Insert Sealing Surfaces: Do not apply filler directly to PTFE, Viton, or other elastomeric sealing surfaces that require direct contact with mating components.
Step 3: Cure and Assembly
- Initial Cure: Allow 20-30 minutes at room temperature before handling assembled components.
- Full Cure: Allow minimum 4 hours before pressure testing or full operational deployment.
- Assembly Torque: Follow standard valve assembly torque specifications. Kamomis Filler should not affect torque values but provides additional sealing redundancy.
Pressure and Performance Specifications
Understanding the pressure-bearing characteristics when Kamomis Filler is combined with valve inserts helps in proper application selection. The following data represents typical values under standard test conditions:
| Configuration | Max Working Pressure | Test Pressure | Burst Pressure |
|---|---|---|---|
| Valve inserts alone | PN16-PN100 depending on class | 1.5× working pressure | 3-4× working pressure |
| Kamomis Filler + metallic inserts | PN16-PN64 | 1.5× working pressure | 3.5-4.5× working pressure |
| Kamomis Filler + elastomeric inserts | PN16-PN40 | 1.5× working pressure | 3-4× working pressure |
| Kamomis Filler + ceramic inserts | PN16-PN100 | 1.5× working pressure | 4-5× working pressure |
These values indicate that adding Kamomis Filler to valve insert assemblies provides measurable improvement in burst pressure margins while maintaining working pressure capabilities within standard industrial ranges.
