Weatherproof Rubberized Undercoating Spray 2kg For Maintenance

Chassls Guarder Blocks Noise Transmission While Sealing Component Gaps

Function:

• Forms a hydrophobic shield on metal surfaces, blocking electrolytic corrosion.
• Elastic polymer filling maintains joint integrity under dynamic loads.
• Acoustic damping technology absorbs 85%+ impact noise (SAE J1477 certified).
• 3mm reinforced matrix withstands 120km/h gravel strikes (DIN 55996 tested).

Specification:

Product Advantage:

• Utilizes molecular-level film-forming technology to create a covalent-bonded passivation layer on metal substrates, effectively blocking H₂O/Cl⁻ penetration paths (Compliant with ISO 4527 standard).
• Features thermal expansion coefficient matched to steel components, maintaining gap sealing below 0.02mm under -40℃~150℃ operating conditions.
• Three-layer porous structure design achieves 12dB insertion loss in 200-5000Hz frequency range (Laboratory tested conditions).
• Shore hardness 65D elastomer coating absorbs 5J impact energy (ASTM D5420 certified testing).

Usage Method:

1. Thoroughly clean the underbody using a high-pressure washer to remove dirt, grease, and loose rust particles.
2. Protect sensitive components (exhaust system, brake lines, sensors) with heat-resistant masking tape and plastic sheeting.
3. Shake the can vigorously for 2 minutes or use mechanical stirring for bulk containers to ensure homogeneous consistency.
4. Hold the spray gun 20-30cm from surface and apply in crosshatch pattern (45° overlapping passes) at 3-4 bar pressure.
5. Allow 15 minutes flash-off between coats. Full cure achieved after 24 hours at 25°C (extend to 48 hours below 15°C).

Precautions:

• Strictly avoid application during precipitation or when relative humidity exceeds 80%.
• Surface temperature must be between 5-50°C (measured by IR thermometer).
• Mandatory PPE: Chemical-resistant gloves (Nitrile), full-face respirator (OV/P100), and protective coveralls.
• Ground all containers during transfer to prevent static discharge.
• Use only stainless steel spray tips (0.021-0.025" orifice) with 3M™ PPS cup system.
• Vehicles must remain stationary for minimum 8 hours after coating.
