Visco-Elastic Anti-Corrosion Paste

Product Description

Visco-Elastic Anti-Corrosion Paste is a highly conformable filler material. It is the ideal companion product to the Visco-Elastic Tape for protecting flanges, valves, pipe fittings, bolts, and other uneven substrates.

The paste fills cavities, sharp angles, and recesses, creating a smooth, continuous profile. This allows the Visco-Elastic Tape to wrap seamlessly without bridging or leaving voids, eliminating the primary entry points for moisture and oxygen.

Manufactured with the same advanced polyisobutylene (PIB) technology, the paste offers self-healing properties, permanent flexibility, and excellent sealing performance. It complies with key international standards such as ISO 21809-3.

Key Features

• Superior Filling — Perfectly fills cavities and creates a smooth surface for tape application
• Prevents Bridging — Eliminates voids, stopping corrosion at its source
• Full Compatibility — Same PIB-based chemistry as the tape, ensures a perfect bond
• Easy to Apply — Hand-formable, no mixing, no heating required
• Non-Curing — Remains flexible for the entire life of the asset

Application Guide

Apply the paste directly into pits, bolt recesses, weld seams, and flange crevices. Press firmly to ensure full contact, then smooth the surface. Apply the Visco-Elastic Tape immediately over the paste for a complete sealing system.

Installation Guide & Precautions

Installation Method

The Visco-Elastic Paste is applied by hand. It is a soft, conformable material that can be pressed directly into cavities and recesses. No mixing, heating, or special tools are required.

Quick Installation Steps

1. Surface preparation: Clean the steel surface to St2 grade (hand tool cleaning). Remove loose rust, dirt, and moisture.
2. Apply paste: Take an appropriate amount of paste. Press firmly into flange crevices, bolt recesses, weld seams, and any surface irregularities.
3. Shape and smooth: Use gloved hands or a simple scraper to level the paste, creating a smooth, continuous surface flush with the surrounding area.
4. Wrap with tape: Immediately apply Visco-Elastic Tape over the paste while the surface is clean, following the tape installation guide.

Key Reminders

• Fill completely — Ensure no air pockets remain inside cavities. Press firmly.
• Do not leave exposed — The paste is a filler, not a final coating. It must be covered by Visco-Elastic Tape.
• Use on irregular shapes only — For smooth pipe surfaces, the tape alone is sufficient.
• Apply tape immediately — Once the paste is shaped, wrap with tape without delay to prevent contamination.
• Store in a dry, cool place below 35°C, away from direct sunlight and heat sources.
