Peramin SMF - sulfonated melamine polymers
Peramin SMF are sulfonated melamine polymer. It is the reference range of conventional plasticizers for drymix mortars, gypsum and concrete materials, due to their consistency, robustness and excellent cost-performance ratio.
As a superplasticizer, it enables users to achieve high flow properties and reduce water content in self leveling compounds and screed technology. Superplasticizers are high-range water reducing additives used when the dispersion of particles in suspension is required to modify mortars and concrete. They allow for a large reduction of the water content without affecting their workability, shorter setting time, lower shrinkage and higher mechanical strengths. They can also enable greater flowability with the same water content, meaning a decrease in viscosity, which results in excellent flow properties, as well as very good self-leveling properties. Typically, the dosage normally lies in the range of 0.1%-0.8% of the dry mortar total weight, depending on the kind of superplasticizer and performance required.
During its initial stage of use, Peramin SMF provides a long working time, flowability and water reduction. During setting, it provides consistency, robustness and regularity of color. And, once installed, it guarantees high mechanical strength.
There are seven main products in the Peramin SMF range. Peramin 10 through 31 are powdered sulfonated melamine superplasticizer, while F40 comes in liquid form.
Peramin® SMF 10 is the reference grade for all applications.
Peramin® SMF 11 enhances flow and is especially recommended for dry-silo mortars.
Peramin® SMF 20 has a low release of free formaldehyde.
Peramin® SMF 22 also has a low release of free formaldehyde and comes especially recommended for use with calcium sulfate binders.
Peramin® SMF 30 enhances flow under weak mixing and provides a good wetting effect, especially recommended for fluid tile adhesives.
Peramin® SMF 31 increases open time through its controlled retarding effect.
Peramin® F40 is the liquid reference within the Peramin SMF superplasticizer range.
The Peramin SMF range can also be used in combination or association with Peramin® AXL, CONPAC, DEFOAM and SRA additives.
