Redispersible polymer powders (RDP) are widely used in the construction industry for their ability to enhance the properties of dry mix mortars. The main types of redispersible polymer powders currently used in the market include: 1. Vinyl Acetate Ethylene (VAE) Copolymers Properties: Good flexibility, strong adhesion, water resistance, and workability.Applications: Tile adhesives, exterior insulation and …
Concrete is one of the commonly used materials in construction projects. However, in certain situations, traditional concrete mixes may not meet the specific requirements of a project. This is where concrete admixtures play a crucial role. Concrete admixtures are materials that improve the properties of concrete. By adding different types of admixtures, concrete’s workability, strength, …
Vinyl acetate-ethylene (VAE) copolymer is a type of copolymer resin that is widely used in various applications, including adhesives, paints, coatings, and construction materials. It is made by the copolymerization of vinyl acetate (VAC) and ethylene (E), two different monomers. Here’s a breakdown of the components: Vinyl Acetate (VAC): Vinyl acetate is a colorless liquid …
Polycarboxylate superplasticizers, often referred to as PCEs, are a type of high-performance water-reducing agent used in the construction industry. They are chemical admixtures that improve the workability and performance of concrete and other cement-based materials. These superplasticizers belong to the family of polycarboxylate ether (PCE) polymers. They work by dispersing cement particles and preventing them …
What is Drymix Mortars? Dry mix mortars, also known as pre-mixed mortars or dry-pack mortars, have gained significant popularity in the construction industry due to their convenience and ease of use. These mortars consist of a mixture of cement, sand, and performance additives, which are pre-blended and packaged for ready-to-use applications. One essential additive used …
