- How It Works
AV-290 is a dual-component hydrophobic resin that reacts within seconds and cured rigid, impermeable and closed-cell with nearly 2,600% the initial liquid volume. The two components of AV-290 (Part A and Part B) are mixed via static mixer at the point of injection and quickly produce a very rigid grout.
- Ratio
1:1 (Part A to Part B)
- Cleaning Products
• AV-208 Technical Grade Acetone™ (CAS# 67-64-1) – removes moisture from equipment
• AV-284 Pump Wash™ (Proprietary Blend) – removes uncured resin from pump and hose
• AV-222 Cleaner™ (Proprietary Blend) – removes cured resin from equipment- Mix Procedure
Avanti’s static mixers are recommended for use when using AV-290 via cartridge or pump system. Do not mix components in any unapproved container.
- Performance
Flush equipment with AV-208 before and after use to remove moisture and clean equipment. Performance will be influenced by site conditions. If site temperatures are low, heat the product to recommended operating temperatures of 60°F – 90°F (16°C – 32°C). Do not use open flame as a heat source.
