GELNORM^®- Geltimer is an instrument for the automatic determination of the gel time of reaction resins. The design is based on DIN 16 945, DIN 16 916 and EN 14022.
The test with GELNORM^®- Geltimer is very easy to perform and gives exceptionally good reproducibility.
The automatically measurement can be performed for any reaction resin, for example:

• Unsaturated polyester resins
• Epoxy resins
• Polyurethane resins
• Acrylic resins
• Silicone resins

With GELNORM^®- Geltimer it is possible to evaluate all factors which influence the gel time of reaction resins such as type and quantity of hardener, accelerator, inhibitor, filler, pigments, as well as temperature and moisture. The instrument is extremely easy to operate and normally needs no maintenance.
The principle of measurement of Gelnorm®– Gel Timer is simple: A stamper made from aluminium or glass performs an up-down cycle in a thermostatized test tube filled with resin.

When the point of gelation is reached, the test tube is pulled up by the stamper. This stops the clock which was started at the beginning of the experiment and the gel time can be read of.
