Resin CR299 – Hardener CH299
Resin CR299 5 kg Bucket
Hardener CH299 Paste 630 g Bucket
CR299 is a semi – liquid, Blue, epoxy resin, filled with very hard fillers, such as silicon carbide, which when mixed with hardener CH299, Yellow paste, creates a putty resin system.
Especially developed to apply a 40 mm thick layer on top and sides of cell – phone batteries.
Anti -abrasion, hard to sand and cut, for protection against theft of batteries and other valuable equipment. Easy to apply and medium to fast curing. Hardener CH299 provides very high impact strength and toughness and some heat development during setting. To be applied as a putty, by hand.
The final temperature of the epoxy should not exceed 45 C, in order to prevent battery damage. A thermometer should be used (meat cooking type would do), to measure the initial temperature of the resin and hardener, as well as the temperature after mixing the 5,63 kg kit.
If it is a hot day, it may be advisable to apply 10 to 15 mm layers at a time, and measure the temperature of each layer, before application of the next layer. The higher the ambient temperature and the thicker the casting, the more heat will be generated, and trapped within the epoxy.
A slower hardener can be supplied, at the request of the customer. Faster hardeners can also be applied, provided 10 to 15 mm layers are applied, and the following layers applied, once the temperature has cooled down.
The site should be completed once the epoxy has reached about 40 to 50 Shore D hardness.
A very fast setting and a low peak temperature cannot be achieved easily.
