Product Intelligence
Selleys VBS Vapour Barrier: Two-Pack Epoxy Moisture Barrier System
Product Overview
Selleys Liquid Nails VBS Vapour Barrier is a two-part epoxy adhesive system designed specifically for use as a vapour barrier application. This highly cross-linked, pigmented system serves as a critical moisture barrier solution in construction applications, particularly for concrete substrates that require moisture protection before flooring installation.
Technical Classification
The product is classified as an epoxy resin-based system and is designated as an environmentally hazardous substance for transport purposes. It is regulated under multiple dangerous goods classifications for road, rail, marine, and air transport due to its chemical composition.
Key Components
The system comprises two distinct parts:
- Selleys Liquid Nails VBS Vapour Barrier Resin (Reference No: SELGHSEN000294)
- Selleys Liquid Nails VBS Vapour Barrier Hardener (Reference No: SELGHSEN000293)
The hardener is a blue-coloured, viscous liquid product that combines with the resin to create the functional vapour barrier system.
Physical and Chemical Properties
Hardener Component Properties
- Form: Paste/Liquid
- Colour: Blue
- Specific Gravity: 1.2
- Composition: Contains isophorone diamine as a key ingredient
Hazard Classification
The VBS Vapour Barrier system is classified as hazardous according to Safe Work Australia GHS 7 criteria and is designated as a Class 8 Corrosive material. The product contains components classified with:
- Sensitisation - Skin - Category 1 (may cause allergic skin reactions)
Non-Hazardous Classifications
The system is classified as not hazardous for:
- Acute aquatic exposure
- Chronic aquatic exposure
- Reproductive toxicity
- Carcinogenicity
- Mutagenicity
