Product Introduction:
MS910 coating is a one-component waterproof coating made from silane-terminated polyether as the base polymer, with fillers, additives, etc. added. Widely applicable to non-exposed roofs, underground, indoor and balcony buildings, water storage projects, underground pipeline corridors and other waterproof projects. It is also suitable for cold bonding construction of modified asphalt rolls and self-adhesive asphalt rolls, as well as EPS and XPS insulation board bonding construction.
Application Advantages:
(1) No solvent added, no odor, no free TDI, extremely low VOC;
(2) Cold construction, no bubbles on the outside, fast curing, excellent construction application performance;
(3) A composite waterproofing system can be formed with the asphalt roll material, or it can be used as a binder for the asphalt roll material and insulation board, and a separate coating for waterproofing;
(4) High compatibility with base layers such as concrete, stone, wood, metal, as well as insulation boards, polyurethane, asphalt materials, etc.;
(5) Strong adhesion, can be used to mount the vertical wall composite modified asphalt waterproof roll material to resist slippage.

Single-component Polyurea Grouting Material
DNPU-621 is a grouting material that uses polymer polymer resin as the main agent and mixes mineral fillers and additives, and forms polymer elastomers by reacting with water. It is used to cover cracks and solve the leakage and re-leakage of structural cracks such as deformation joints, expansion joints, cross-section joints, settlement joints, etc.
Application Advantages:
(1) High bonding strength, high elongation, good elasticity, and strong ability to adapt to structural deformation;
(2) Consolidation and compactness, water resistance, mineral corrosion resistance, mildew resistance, cold resistance, and water impermeability.
(3) High solid content, free of harmful solvents such as benzene, and is free of pollution to the environment and the human body;
(4) Single-component, liquid, cold construction and convenient construction.

DNPU-202 microcrystalline polyurea grouting material：
Microcrystalline polyurea is a single-component hydrophobic polyurethane grouting material, which is a chemical grouting material that reacts composite polyether polyols with polyisocyanate to form isocyanate blocked. This material is a single liquid high and low pressure infused elastic leak prevention agent, which is easy to mix with water to produce microcrystal foam to form a highly stable tough foam. After acting with water, it can form a water stop foam that rapidly expands slightly and blocks cracks, achieving the purpose of waterproofing and leak prevention. It is widely used in various civil structures and construction projects.
Product Features:
(1) The product has excellent environmental protection performance, low odor, and can be used for indoor grouting.
(2) It has strong adhesion to metals and concrete, strong structure, high toughness, and can withstand water for a long time and has high elasticity.
(3) It can react with acidic or alkaline water without affecting the physical properties of the foaming body.
(4) The viscosity is relatively low, making it easy to apply. It reacts quickly upon contact with water to form the foaming body.
(5) The solidified product has elasticity and can effectively adapt to the waterproof treatment of deformation joints.
(6) It is packaged in a single-component form. It can be used directly after opening the container without the need for complicated preparation.
Application Fields:
(1) The filling joints of building windowsills are blocked;
(2) Waterproof and leak-proofing of underground tunnels, basements, underground garages, etc.;
(3) Leakage plugging of expansion joints and secondary construction joints of construction projects.
