TECHNOBOND 4202 is a two-component, water-based PVAc dispersion designed for surface and structural bonding of wood. It contains reactive groups that are able to cross-link with aluminium ions. TECHNOBOND 4202 is suitable for bonding joints that require water and temperature resistance. It is suitable for: - bonding interior joints that are often intensively and long term exposed to water or air moisture condensate, - bonding exterior joints that are treated with a sufficient surface treatment (e.g. stairs, doors, windows). It is not suitable for static load-bearing structures (roofs, beams).
