Drying Time
When developing a process, it is important to know the exact time it takes for the coating to dry or cure. There are many stages to the coating drying time. Once a coating has been applied, the first stage is that the coating levels off under gravity. Once a coating begins to cure, a thin dry film appears on the surface.
But how to know when a coating is totally dry?
Using the Biuged Drying Time Recorder, the operator can easily identify each of the stages of the drying process：
A ball tip is placed into the coating and, using the mathematical formula： Distance=Speed ×Time ； the Recorder begins to move this ball at a predefined speed. As the coating dries, the trace left in the coating by the ball identifies each stage of the cure.
Intelligent Line Drying Time Recorder
BGD 262 Intelligent Line Drying Time Recorder is a powerful and intelligent line drying time recorder which can meets with all different requirements about analyzing different samples’ drying performance. It has five dividual pairs of tracks (each channel has two working channels). Comparing with BGD 261, BGD 262 has many features as below：
◆ Big size touch screen (5 inch) and shows three channels working parameters at the same time
◆ Very easy and convenient to set working parameters
◆ Broad and flexible time range：can be set varying from 1 minute up to 48 hours. This makes the BGD Drying Time Recorder suitable for fast drying waterborne coatings as well as very slow drying paints that may need days to dry.
◆ Uses photoelectric sensor to accumulate and show real-time position, and can achieve accurate position which precisely corresponds to working time.
◆ With motor drive controlling system which has our own intellectual property to ensure high precision location.
◆ Each channel has LED indicator light to show this channel is working or not.
◆ Come with 6 pcs stainless steel weights (5 gram per weight) for recording through drying
◆ Come with calibration certificate
◆ Comply with standards：ASTM D 5895-03, ISO 9117-4
