SPS-22 Water Reducing Type Polycarboxylate Superplasticizer PCE Powder


SPS-22 is a new generation of Eco-friendly high performance polycarboxylate ether superplasticizer powder developed by our company with EPEG 912 ( MW:3000) as main raw material.

Product details

Technical Principle

The main chains of the high performance polycarboxylate water reducing agent molecular are absorbed onto the surface of the cement granules, which can effectively hinder the hydration, enhance  fluidity retention ability, the branch chains surrounded by the cement granules, play dual roles of steric hindrance and electrostatic repulsion, it is totally different from conventional water reducing agents, so the high performance polycarboxylate water reducing agent has better dispersion and water reducing effect. 


1) SPS-22 Polycarboxylate ether superplasticizer powder with solid content : 97% min. It is specially optimized for plastification and water reduction of construction chemicals.

2) Having a good thermostability to 100(one hundred celsius degree centigrade).

3) Provides an excellent development of early strength
(4) With a good dispersion, an excellent adaptability to different cements, and good water-reducing properties.

1. It is specially used for gypsum based self-leveling floor screeds and cement based dry mix mortar.

2. It is especially for cementious self-leveling underlayments (SLU), plaster and masonry, non-shrink grouts, pressed cement slurry, self-leveling floor screeds, waterproofing mortar, repair mortars, injection mortars, dry mix concrete, tiles adhesives and joint fillers.

3. Used in oil well cementing processes as a dispersing additive to cement slurry in order to regulate rheological properties, to reduce hydraulic resistance of cement slurry, and to reduce pumping and squeezing pressure.

Usages and Cautions:
(1) A recommended dosage is 0.1%-0.6% by the weight of cementitious materials. Actual dosages should be determined by test.
(2) This product is forbidden to be mixed with naphthalene sulphonate.
(3) Compatibility test must be done when it is used together with other admixtures.
