powdery screed material premixed with special cement, super-plasticized component, optimized proportioning/aggregating component

Product Introduction

Polar Bear Brand cement-based self-leveling material is a kind of powdery material that is premixed by factory with special cement, super-plasticized component, optimized proportioning/aggregating components as well as organic modified component in proper proportion. When being used, the material can be mixed to even flow pattern material with self-leveling function after adding water. It is applicable to construction of ground which has strict requirement on flatness, and it can be conveyed with mechanical pump or by manual operation. Based on its functions the material can be divided into 2 types, namely self-leveling material for surface course and self-leveling material for bedding course.

Performance Features

1.  Fast speed of construction: large area disposal on ground can be done within 1 day.
2. Fast and high intensification: based on ultrahigh intensity HCSA cement, the self-leveling material becomes intensive very fast, so the construction schedule can be expedited; and its intensity at later stage is high.
3. High flow performance: the material is very easy to mix and stir at working site and it can flow to the designated place and automatically level up without any outside force or auxiliary measures when being poured.
4. Convenience for construction: As pre-packed material it is very convenient to use, just mix it with water is okay, and the materials consistency and evenness are ensured. Also the material can be conveyed with pump.
5.   Stable volume: the material has very low shrinkage, and it can be used for large area seamless construction.
6.   Environment friendly, innocuous, inodorous, non pollution, non radioactivity
7. Economic higher performance-price ratio than epoxy resin ground materials

 

Applicable Scope

Serve as leveling material for bedding courses of epoxy resin and PU etc. Serve as leveling material for bases of PVC, ceramic tiles, carpet, and wood board etc. Serve as wear resistance material of surface course. Serve as color decoration material of surface course. .
 

Product Selection

Product	Type	Product Description
Rapid Hardness Type	Surface Course	The wear-resistant surface course is applicable to the reconditioning of industry workshop ground or new built project with short construction schedule in spring, autumn, and early winter. If it is necessary resin can be painted on its surface.
CSA-1	Surface Course	The wear-resistant surface course is applicable to the reconditioning of industry workshop ground or new built project in spring and autumn. If it is necessary resin can be painted on its surface.
CSA-2	Bedding Course	It is applicable to level the base concrete which shall be painted with resin wear-resistant surface course and has certain requirement on intensity of bedding course.
CSA-3	Bedding Course	It is applicable to level the base concrete which shall integrate with resin, PVC, ceramic tiles, boarded floor etc.  and has no special requirements on intensity of bedding course
