Polycarboxylic Acid Superplasticizer, also called polycarboxylate superplasticizer, is recommended in cement-based materials systems with good water-reducing effect and slump retention property, can provide good fluidity and workability of materials, and improve early and final strength of cement-based materials.
Hydroxy Propyl Methyl Cellulose (HPMC), is a natural multifunctional carbohydrate polymer, white or similar to white fiber or granular powder. It has two components: hydroxypropyl group and methoxy subgrade group. Each of annulus fibrosis are three hydroxyls.
Re-Dispersible Polymer Powder(RDP, VAE) is the powder form of a special emulsion (macromolecular polymers) after spraying and drying. It’s also called dry powder glue. It dissolves in water easily and quickly forms emulsion, the same with the original emulsion. The membrane will form after the moisture is evaporated, this kind of membrane possesses high flexibility, good climate resistance and high adhesive to various substrates.
Hydroxy Ethyl Cellulose(HEC) is designed for use in oilfield cementing application. This product provides water retention properties when add to typical cement formulations, leading to more consistent, stronger, more uniform cement.
