| [Description] |
SC900 Series PU product with
superior physical property is a material of
environmental protection with properties of non-solvent,
non-pollution under research and development of Sea
Chief Co.,Ltd., besides, it has equipped with rapid and
easy construction for the work. As this material has
excellent physical performance, it is a flexible
protection membranes and available to coat on the
surface with high physics, superior wear-resistant, and
superior solvent-resistant.
SC900 series can be used the
dual-liquid high-pressure sprayer for construction, and
it also can be used by traditional manual trowel for
integrated one-piece forming, seamless, and required
thickness at a time. In addition to be used for cement,
metal, timber etc., it can be applied for PS and PU
Foam, etc. for protection. |
