Powercrete R65/F1 400ml Cartridges and Heating
|A Powercrete R65/F1 400ml Cartridge|
Spraying Powercrete R65/F1 is really a beautiful product. The R65 goes on quickly, it goes on very uniformly, it cures quickly and it is an all around great, great pipeline corrosion prevention coating. One of the challenges can come here: the material sprays on the best when it is sprayed when the material temperature is 50-60C (122F to 140F). This temperature can be achieved many ways: hot box, water immersion or oven being the most consistent.
The manufacturers of the cartridges and pistons (and other associated components) indicate that their cartridges should not be heated to temperatures higher than 150F. At 150, some of the components which can be nylon will soften slightly. This can cause a piston to blow out if a higher than recommended temperature is matched up with a certain air pressure.
So, it is critical that all possible steps be taken to keep that material heat temperature within the manufacturers suggested range of 122 to 140F.
