Types of putty powder thickeners

Putty powder thickener can be a commonly used additive, generally utilized to increase the viscosity of putty powder to make it easier to construct and utilize. There are several forms of putty powder thickeners currently out there, which is often split up into the subsequent groups based on their components and utilizes:

1. Salt carboxymethyl cellulose (CMC) thickener

Sodium carboxymethyl cellulose is actually a organic cellulose derivative, and its thickening result mainly depends upon the duration of the molecular sequence and also the standard of cross-undefinedconnecting within its option. CMC thickeners have good viscosity stableness under medium sized and high shear charges, offers high preliminary viscosity, and possess very good sag level of resistance, workability and storing stableness. However, it needs to be mentioned that CMC thickeners have relatively poor ecological performance and consist of hazardous materials like formaldehyde, so basic safety and environment issues must be compensated focus on while in use.

2. Polymer emulsion thickener

The main components of polymer emulsion thickener are acrylic acid solution, polyacrylamide along with other polymer emulsions, that contain very good thickening result and building functionality. This type of thickener is non-harmful and odorless, has great environment overall performance, and can enhance the adhesive force, crack amount of resistance and h2o amount of resistance of putty powder. Nonetheless, it must be observed that this sort of thickener may change the overall performance in the coating movie, so focus has to be paid to the compatibility with many other preservatives during use.

3. Cellulose ether thickener

The key aspect of cellulose ether thickener is hydroxyethyl cellulose (HEC) or hydroxypropyl cellulose (HPC), which can give substantial viscosity and program viscosity, along with excellent sag amount of resistance and paintability. . This sort of thickener is non-dangerous and odorless, has very good environmental efficiency, and can increase the sticky power, crack level of resistance and water level of resistance of putty powder. However, it must be noted that this type of thickener may impact the performance of the covering motion picture, so focus needs to be paid for to the compatibility along with other additives while in use.

4. Normal plant thickener

All-natural vegetation thickeners are mainly taken from plants, like starch, pectin, carrageenan, and many others. This particular thickener is non-poisonous, bland and possesses good environmental efficiency, nevertheless the thickening result is relatively very poor. Organic grow thickeners can be used along with other thickeners to have far better thickening results and development performance.

In a nutshell, different putty powder thickeners have diverse characteristics and extent of use. During use, it is actually necessary to choose the appropriate thickener according to the actual condition, and take note of safety and enviromentally friendly troubles. Simultaneously, also, it is required to concentrate on the compatibility with other chemicals to ensure the overall performance and stability from the putty powder.
