Wet Surface Bonding Additive for Building Materials
Overview
NAMI has developed an additive technology to enhance bonding over wet surfaces.
Commercialisation opportunities
Non-exclusive licensing
Problem addressed
Adhesion on wet surface is always a big challenge in building. Silicone sealant incorporated with NAMI’s bonding additive enables good bonding strength on wet surface, exceeding the basic requirements for site works.
Innovation
- This is a bio-inspired additive technology to maintain over 70% bonding strength on wet surface.
Key impact
- Diversified applications and can be integrated in various building materials such as coatings, sealants, adhesive and tape, etc.
- Effective with low dosage of 5wt% or below
- Mild synthetic conditions for additive manufacture
- Non-toxic and environmental friendly
Application
- Movement joint filling for various wet substrates for window, curtain wall, bathroom, etc.
- Adhesion for floor, wall, roof, etc.
- Water leakage repair for pipes
