Chemspartic PU
High-performance, 2-component, solvent-free, polyaspartic -PU-based, liquid-applied elastic waterproofing membrane
Product Description
Salient Features
Elasticity and Flexibility:
This membrane exhibits excellent elasticity, allowing it to stretch and flex with substrate movements and temperature changes without cracking.
Crack-Bridging Properties:
The primary feature is the ability to bridge cracks in the substrate, preventing water ingress and protecting the underlying structure from damage.
Waterproofing:
creates a seamless and waterproof barrier, preventing water penetration and protecting the structure from water-related damage, such as corrosion or deterioration.
Overcoatability:
Chemspartic PU can be overcoated with subsequent layers of PU and epoxy-based sand broadcasted systems like Floorchem and Chemdeck, making it suitable for waterproof antiskid car deck coating systems.
Quick Curing Time:
Fast-curing formulations allow for quicker installation and reduced downtime.
Easy Application:
Designed for ease of application, these membranes can be applied by spraying, rolling, or brushing.
Compatibility with Various Substrates:
Chemspartic PU is suitable for application on various substrates such as concrete, metal, wood, and existing coatings. Designed with low VOC (Volatile Organic Compounds) content, contributing to environmental sustainability and indoor air quality.
