polyurea special hole-sealing putty

Description

DS101 Polyurea Special Hole-Sealing Putty is a high-performance, two-component, polyurethane-modified paste formulated with advanced polymer technology. It is specifically engineered for sealing and filling holes, cracks, and surface defects in harsh environments, making it particularly ideal for substrate preparation in polyurea coating systems. This product not only inherits the excellent physical properties of polyurea but is also optimized for enhanced application and adaptability. It serves as the critical, premier choice for ensuring the integrity and long-term durability of the entire protective coating system.

Product features and advantages

(1) The coating is seamless, tough and compact

(2) Strong adhesion, excellent impact resistance, collision resistance and wear resistance

(3) Excellent anti-corrosion and chemical resistance, such as acid, alkali, salt, etc

Application scope

It is suitable for leveling, joint filling and hole sealing of metal base, concrete and cement mortar plastering.

Product application temperature

Environment temperature: 5-38℃

Relative humidity: 35-85%

The concrete surface should be PH<10, the substrate water content less than 10%

Dew point ≥3℃

Application tips

Recommended dft: 1000 um

Interval time: min 3h, max 168h, if the maximum interval time is exceeded or there is dust on the surface, it is recommended to use sandpaper to polish and clean before application.

Coating method: scraping

Application note

To ensure the surface is perfect and clean, remove the oil, mold, dust and other attached dirt on the surface, also remove the loose part to make sure it is solid and dry.

Mix the paint evenly before use, pour out the amount to use up, and close the lid immediately. The mixed paint must be used up within 60 minutes. Do not return the remaining products to the original paint barrel.

Mix part A and part B in right ratio, then mix with quartz sand or quartz powder together for use.

Do not add organic solvents or other coatings.
