Sulfonated melamine formaldehyde powder

Product Description

Sulfonated Melamine Formaldehyde,also name as Melamine sulfonate formaldehyde condensate,or melamine formaldehyde sulfonate or Melamine Formaldehyde Sulphonate polymer, is a highly effective water-reducing agent and superplastiziser for promoting accelerated hardening and free flowing concrete,cement and plasters. It is suitable for use in tropical and hot climatic conditions.

 

Use

Sulfonated Melamine Formaldehyde is used as a superplastiziser to produce free flowing concrete in:

- Floor slabs

- Foundations

- Slender components with densely packed reinforcement

- Walls and columns

- Beams and slabs

 

Sulfonated Melamine Formaldehyde is used as a water-reducer in the manufacture of high early strength concrete for:

- Pre-cast concrete elements

- Bridges and cantilever structures

- Pre-stressed concrete

It is also used for high strength gypsum,gypsum based self-leveling,wall plaster,gypsum based putty powder etc.

 

Advantage

Sulfonated Melamine Formaldehyde provides the following properties:

As a Superplastiziser

- Substantial improvement in workability without increased water or the risk of segregation.

- Normal set without retardation even when overdosed.

As a Water Reducer

- Up to 20% water reduction.

- 40% increase in 28 day strengths. High strengths after 8 hours.

- Increased frost resistance.

- Increased water tightness.

Application Details

Dosage    

1.0%-1.5% by weight of cement. It is advisable to carry out trial mixes to establish the exact dosage rate required.

 

Dispensing  

Sulfonated Melamine Formaldehyde can be added separately to the fresh mixed concrete or directly to the mixing water prior to its addition to the aggregates.

When added separately to the freshly mixed concrete, further mixing must take place for at least one minute per cubic meter.

 

Concrete Placing   

The standard rules of good concreting practice (production as well as placing) must also be observed when using Sulfonated Melamine Formaldehyde concrete.Fresh concrete must be cured properly.

Curing   

Fresh concrete must be cured properly, especially at high temperatures in order to prevent plastic and drying shrinkage.

Compatibility

Sulfonated Melamine Formaldehyde is compatible with sulphate resistant cement. Pre-trials are recommended if combinations with the above products are being made.

Please consult our Technical Services Department.

 

Cleaning

Clean all equipment and tools with water immediately after use.

 

Remarks

When accidental overdosing occurs, the set retarding effect increases, however, no excessive amount of additional air will be entrained. During this period the concrete must be kept moist in order to prevent premature drying out.

Safety

Precautions

Accidental splashes to the skin must be washed off with water and soap.

Accidental splashes to the eyes or mucous membrane must be rinsed with clean warm water. Seek medical attention without delay.Skin barrier cream, safety goggles and rubber gloves are recommended.
