Sulfonate Melamine Formaldehyde Resin High Strength Concrete Admixture

Sulfonate Melamine Formaldehyde Resin Super Plasticizer- High Strength Concrete Admixture
 
JF SULFONATED MELAMINE FORMALDEHYDE RESIN Product Description:
Melamine formaldehyde resin referred to as melamine resin, MF, the processing of cross-linking reaction, products for the insoluble not melting thermosetting resin, often used to it and urea formaldehyde resin collectively known as amino resin. After curing, the melamine formaldehyde resin is colorless and transparent, stable in boiling water, and can even be used at 150℃, and has self-extinguishing, arc resistance and good mechanical properties. Widely used in wood, plastic, coating, paper, textile, leather, electrical, pharmaceutical and other industries.

Melamine-formaldehyde Resin Usage:
1. Used for and widely for self-cured, vapor-cured concrete and its formulations. At the early stage of application, extremely prominent effects are shown. As the result, the modulus and site utilization can be drastically, the procedure of vapor cure is omitted in peak-heat summer days. Statistically 40-60 metric tons of coal will be preserved when a metric ton of the material is consumed.
2. Suitable for preparation of early-strength, high-strength, high-anti-filtration and self-sealing& pumpable concrete.
3. Widely used in pre-cast & ready-mixed concrete, armored concrete and pre-stressed reinforced concrete in key construction projects such as dam and port construction, road building & town planning projects and dwelling erections etc.
4. Compatible with Portland cement, normal Portland cement, Portland slag cement, fly-ash cement and Portland pozzolanic cement etc.
 
Melamine Formaldehyde Resin Properties:
 
Melamine formaldehyde resin is made of melamine and 37% formaldehyde aqueous solution reaction, because the reaction conditions are different, so the amount of molecules produced is different, its products have from water soluble to insoluble in water, and then to insoluble solid are not melting.
 
Melamine-formaldehyde Resin Dosage:
Dry mixed homogeneously with other ingredients of dry mortar and packaged as one product, which can be at job site mixed with recommended dosage of water for application.
Recommended dosage is 0.30-1.00% based on binder weight. The detailed dosage should be determined by test in advance according to local raw materials and construction regulation.
 
Package,Storage & Transportation:
 
For powder, packed in 25kg PE-lined woven bag.
Storage and transportation should be carried out in cool and dry condition. Under high temperature and high humidity, product should be kept away from moisture and pressure to avoid coalescence or agglomeration.
