Drying Time Recorder- Some Useful Info You Need to Know About It

Definition:

Line or linear drying time recorder also known as the surface drying time recorder is a device that is used to define the different stages of the drying process of the paint or surface coating as well as note the time required to dry the paint. To get the best result, we need to place the instruments and perform the tests under controlled conditions. Dry time recorder is best for measuring various stages of drying and curing that occur in films are easy to detect but difficult to define in terms of chemical and physical principles. A versatile drying time recorder to help quantify the various stages of film curing and drying, delivers reproducible results, and guarantees highest efficiency. It is also used for determine the absorption behavior and drying time of inks printed on paper, carton, plastic or metal foils

We, at Caltech India, are one of the leading Drying Time Recorder Manufacturer and supplier, producing high quality and high accuracy instruments.

Construction and Test Procedure:

The drying time recorder consists of components like: the main body, needles, glass strips, a digital display, a time scale, and the coating material. At first, the coatings are applied to the 6 glass strips, and then the needles are set in the initial position. After that, a time is set (For ex, it can be 6, 12, 24, or 48 hours) for the needle to go across the other end. After the needle has reached the other end, the glass strips are examined as well as the drying time is found with the help of the lines made by the needle on the coating material.  It Conforms to ASTM D5895.

The hemispherical needle and the tracks go through various stages of the paint or coating and the quality of lines by the needle are produced accordingly. For example;

1. During the evaporation of the solvent, the needle makes a deep pear-shaped impression.
2. During the sol-gel transition, the needle makes a continuous track on the film.
3. When the surface becomes dry the needle draws interrupted tracks on the surface film.
4. And when the surface is completely dry the needle does not penetrate the film hence no lines are made.

What we have to offer:

We, at Caltech India, are one of the leading Drying Time Recorder Manufacturer, offering great quality products with reproducible results and the highest accuracy. Our offering BGD 261 is one of the best Drying time recorder instruments in the market to test the drying time or the gelation behavior of many paints. These paints are applied on the glass strip of 300*25 mm with the application of our cube applicator BGD 203. The hemispherical needle travels on the prepared test tracks over the time interval you have selected. (For example, it can be 6, 12, 24, or 48 hours)

Features:

• Intuitive design
• Simultaneous 6 strips or tracks for examination
• Accurate results
• High-quality glass beds
• Four different speeds like 6,12, 24, or 48 hours for any application

Key Takeaways

• Linear drying time recorder is a device that is used to define the different stages of the drying process of the paint or surface coating.
• The drying time of at room temperature for 24 hours is a general time for alkyds, varnishes or paints. It is determined by adding the requisite drier and thinning to a viscosity at which the material is normally applied.
• It is also used to note the time required to dry the paint.
• The drying time recorder consists of components like: the main body, needles, glass strips, a digital display, a time scale, and the coating material.
• The hemispherical needle and the tracks go through various stages of the paint or coating and the quality of lines by the needle are produced accordingly.
• After the needle has reached from one end to another, the glass strips are examined and the drying time is found with the help of the lines made by the needle on the coating material.
