We have talked about catalyst long and hard on this blog, a post you can read HERE. But now we are going to look a little more closely at the different Norox products offered in gallon size and up. There are some differences, which most people aren’t aware of, so, let’s highlight those differences here so you can be sure you are getting the perfect product for the job.
These products are offered in both red and clear. The red catalyst is preferred for resin applications so you can easily see if the resin and catalyst is properly mixed. The red color isn’t used for gelcoat as it will affect the color.
Norox MEK-P 9 – The standard catalyst for Noroc, the MEK-P 9 gives consistent room temperature performance with both resins and gelcoats. A reliable product of high purity assures quality in every system.
Norox MEK-P 925 – High dimer content gives excellent performance in most Vinylester resins. 925 also performs well when used with General Purpose and Isophtallic resins. This product is what is used for the 1 oz, 2 oz, 8 oz, pint and quart bottles. This is what is used when a customer wants “high-point 90.”
Norox MEK-P 9H – This product features a reduced level of hydrogen peroxide. 9H is particularly useful in critical gelcoat applications. Another application is in heated, continuous mixing systems for polymer concrete.
Noxox MEK-P 30 – A reduced strength version of the 9, the 30 provides the fabricator more accurate metering control in hot weather or with a highly reactive resin. This is a favorite during the hot summer months.
