Norox MEK-P Catalyst Guide

catalystWe 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.

Let’s talk Fiberglass

Let’s talk Fiberglass, everyone! Here at Fiberglass Coatings, our techs know a thing or two about fiberglass and they are always looking to help. We have some different fiberglass for different jobs, so let’s cover a few of the main types. Most of these are offered in different widths and are sold by the roll or by the yard.

 

mat
1-1/2 oz Mat

Mat – It’s the most basic and widely used type of fiberglass we have. The roll is a whole bunch of small fibers thrown together on a binder. There is no specific direction to the fibers, which makes them pretty universally strong and light. This is sold in anything for ¾ oz all the way up to 2 oz thickness. Mat is generally used for parts, more than anything. It’s also great for not showing fiberglass patterns through the gelcoat.

 

 

woven roving
24 oz Woven Roving

Woven Roving This is a weave, where the long fibers are weaved together like a cloth. They are extremely thick and durable but are also heavier than other fiberglass materials. They aren’t used as much because they often print their pattern through gelcoat, but you will still see this glass for heavy duty items.  Woven Roving is sold in 18 and 24 oz thickness.

 

 

45-45 1708
XM1708

Double-Bias – This is a combination of the two previous fiberglass materials. This product has woven roving on one side and mat on the other, offering the best of both world and making a very sturdy part. This product can also be used for boat and house decks due to its rigidity. This product is sold in 1208, 1708, 2408, and 3610, where the first number is the woven roving thickness (12 being 12 ounce Roving, and 08 being the mat thickness, or in this case ¾ oz).

These products come in one of two types of weaves, or orientations of the fiberglass. The first is referred to as the CM or 0/90 weave. In this case, the weave goes horizontally and vertically, so, it’s stronger for things like stringers. There is also an XM version that is a +/- 45, so they have crossing 45 degree angles. This makes the glass stronger, but it does not fold and bend as easy.

 

6 oz cloth
6 oz Cloth

Cloth Fiberglass cloth is a very fine material, adding rigidity but also providing a good looking product for anything that is see-through. It is very common for surfboards as it’s thin and lightweight and looks nice with clear resin covering it. It’s sold in 4 oz, 6 oz, 8 oz and 10 oz thicknesses.

 

Carbon Fiber – Known for it’s superior strength to other fiberglass material, Carbon Fiber is an extremely popular choice. The material is very light and very durable. Carbon Fiber does not have a binder, the cloth is simply weaved together in different variations, generally called Twils. We carry a Carbon Fiber and a Combo cloth. Carbon Fiber is also the most aesthetically pleasing of the products we have.

5 tips on using PVA Release Agent

pvaPartall Film #10 or more commonly called PVA (short for Poly Vinyl Alcohol) is a liquid release agent that helps with pulling parts out of a mold. If you haven’t used this yet, this will make your mold pulling much easier. Here are a few tips to get you going.

  1. PVA is soluble in water, which means when you are done, all you need to do is wash your part off.
  2. Before applying PVA, make sure your plug is properly waxed with a paste wax.
  3. Apply PVA by either spraying or wiping the green liquid on with a sponge. It will foam slightly, but dry to a clear, glossy shine. Once applied, let sit for 15-30 minutes to dry, depending on how hot it is.
  4. If you are using a new mold, you will want to use multiple coats, letting each dry before applying the next.
  5. The part should easily come off. You may also try injecting air into the mold to help, or even water.

So, the next time you need to pull a part, grab a bottle of PVA. PVA is sold in pints, quarts, gallons, 5-gallon pails and even 55-gallon drums and it will make your life so much easier!
