KingAdd 100AC®
Liquid acrylic copolymer additive for GFRC.
Overview
KingAdd 100AC is a high solids single component acrylic copolymer emulsion. It is designed to improve the physical properties of GFRC systems (Glass Fiber Reinforced Concrete). GFRC is an environment friendly composite system with low consumption of energy and used to produce great varieties of products based on cement-based composite material reinforced with alkali-resistance fiber. The fibers add flexural, tensile and impact strength and the resulting material allows the production of strong light weight products used in architectural, civil engineering and many other applications. GFRC has reached a great position among Architects, Designers, Engineers and end users for its flexibility to meet performance, appearance, and cost.
Applications
- KingAdd 100AC is used in the formulation of glass reinforced concrete products. As GFRC is a mixture of several materials, the properties of GFRC vary with the production method, amount and type of glass fiber and composition of the cementitious matrix. In this matrix KingAdd 100AC plays a major role in achieving the long- term physical properties (especially the flexural, tensile, flexibility, etc.) and the elimination of the wet cure process for achieving the maximum strengths
- GFRC having KingAdd 100AC is used in:
- Artificial rock designes
- Concrete lining for durability
- Architectural panels and land scape areas
- Composite mouldings counter top systems
- When using KingAdd 100AC it is better to add it after adding the water and plasticizer inside the mixer while it is running
- As wet curing is not needed in this system, it is advisable to protect the applied areas during the night by covering it with suitable polyethylene sheets. This action will give better strengths because it controls the heat of hydration during the initial setting time
Advantages
- Eliminate the need for wet curing
- Improve significantly the physical properties especially the flexural strength
- Improving the workability, and the consistency of the cementitious matrix
- Gives a sprayable non-sag mix
- UV stable polymer
- Chloride free
- KingAdd 100AC is free from formaldehyde and from any corrosion additives
