Single Component Waterproof Coating VCPU-1
Introduction
VCPU-1 is a mono-component PU waterproof coating produced by addition
polymerization of poly polyol with isocyanate and supplemented with
certain additives and
fillers.
The -NCO end groups in the PU prepolymer react with the moisture in
the air and form a
tough, flexible and seamless waterproof membrane on the coating
base where the paint is applied to.
Regulatory information
Fully meet the technical requirements of GB19250-2003 PU Waterproof
Coating for mono-component
waterproof coating products.
Characteristics
1.Mono-component, available to use when it is opened, easy and
quick execution.
2.Strong tensile strength, high extensibility, excellent high and
low temperature resistance,Well
adapted to shrinkage, cracking and deformation of coating base.
3.Strong adhesive force, no need of brushing treatment agent on
many coating bases which meet
the requirements.
4.Dense film, free from bubbles and holes.
5.Film is formed through chemically react, excellent resistance of
long-term water erosion,
corrosion and mildew.
6.Environmentally friendly, no benzene solvent and coal tar
ingredients.
7.No need to heat, easy to operate.
Application
1.Kitchen, bathroom,floor, balcony and non-exposed roofs.
2.Basement, including Building basement, underground garage, metro
and access in open
cut method.
3.Swimming pools,fountain, ponds and ditches.
4.Top plate at plazas and parking ports
