Product Spotlight: Arjay 6011

6011_pour

We have spent lots of time talking about coring material. Coring is a big part of the fiberglass industry and an essential component in boat making. However, not all coring comes in sheets. One of our many really interesting products is a putty by Arjay products called 6011 Ceramic Putty, and this product can save a lot of work!

The Pourable Ceramic Transom putty is sold in 5-gallon pails and is meant to be a liquid coring material that dries extremely hard and rigid; perfect for transoms or stringers in a boat. Why is that exciting you may wonder? Simple; if you are repairing a soft transom, which is when the wood gets wet and needs replacing; instead of completely replacing the transom, you can simply dig out the wood and pour this product in. Once the gap is filled, and the putty is cured, you are done! Often times, the transom is harder and stiffer than ever before!

So, let’s talk specifics. The exotherm on this putty is relatively low, which means that you can catalyze the entire pail and pour the full five gallons without worrying about combustion. Arjay recommends you catalyze at 1%, so an 8oz bottle of MEK-P Catalyst should do it. Gel time is about 18-20 minutes, so you have some working time with this product. Obviously, you can extend that time by cooling the product down ahead of time.

With large pours, Arjay recommends one single pour, so you want to get everything ready to go ahead time, so you can maximize your time. You CAN do multiple pours with this product. Ideally, you want to perform multiple pours before it cures, but even after it cures, you can add another pour, but it isn’t recommended on anything structural because it does create a bit of a seam.

One important bit of information I learned first hand is not to spill it. Once this stuff cures, it’s extremely hard. It’s a tough grind to get off a surface, so make sure you clean it before it cures.

We even have a Handy-Dandy estimator for how many pails you need. Download it HERE: Arjay6011Calculator

Spider Cracks: The Guide

Spider crack DYK

Spider Cracks are a thorn in many boaters side. They seem to appear out of nowhere, and for no reason. Fixing them can involve more than just slapping on some gelcoat, however, and that is where we come in!

The first step needs to be ensuring that your spider cracks are just that, and not a sign of a soggy core, or a broken support. If the underside looks solid, and the surface is steady, then a spider crack is just a spider crack.

For properly fixing a spider crack, you will want to open the cracks to properly fill them. Usually, the easiest way to do that is with a Dremel. Once you open the cracks to a good size, you can lightly sand the surface and wash it down with soap and water, or Acetone to get the surface clean.

From there, you will want some Gelcoat Putty. Gelcoat putty is sold in many sizes, and only requires you mix in a 1-1/2% ratio of MEK-P Catalyst. Once mixed properly, you can use a putty knife to work the putty in the cracks. Once dry, you will sand to a nice, smooth surface and you are ready for the last part.

Now that you have a nice, smooth surface, you probably notice your white patch is still, well, white. Now you want to apply some gelcoat over the top to cover your patch. We can match gelcoat to a sample you provide, or you can check out the stock colors we have. We even have a brushable gelcoat that just requires you to brush it on and be done.

So, there you have it! Your patch is done, and that pesky spider crack is gone, and your boat is good as new! If you have any questions, you can call our technicians or comment in the section below. We are here to help!

What is Hi Gloss Ultra Clear Epoxy?

We discussed Laminating Epoxy and its 5 great key points about the product such as product comparisons, ratio, cure time, and activator results. If you haven’t had the opportunity to read our blog, (Click Here ).

Now, let’s change gears slightly and talk about Hi Gloss Ultra Clear Epoxy. You may have noticed the Hi Gloss Ultra Clear Epoxy’s first appearance looks similar to Table Top Epoxy and after the cure process, both products obtain a clear result. With the noticeable similarities, we assure you there are also differences that make them stand out. For one, Hi Gloss Ultra Clear Epoxy works great for surfboards and casting because of it’s 2:1 ratio. In contrast, Table Top Epoxy requires a 1:1, thin pours of no more than 1/4 of an inch. This allows a perfect coating application not casting. Hi Gloss Ultra Clear Epoxy 133547provides a clear gloss surface without the need to sand or buff. How is this possible? The results may sound similar to the Table Top Epoxy, however, the Hi Gloss Ultra Clear Epoxy cures to an almost clear finish all due to its zero UV additives. Because the product does not consist of any UV additives, your project will need to be clear coated after it has set up. With its 100% solids epoxy resin system, this product is designed for both laminating, casting and coating applications. It has a great easy wet out with a moderate gel time of 20 – 30 minutes at room temperature in a 1/2 pound mass.

Tip: Cure may be accelerated by mild heat such as lamps or tunnel ovens.

 

5 Key Points on Laminating Epoxy Resin

We can guess that you have used Epoxy before, if not, more than likely you have seen furniture, an object or project with epoxy on it. Now, Epoxy is not the same as Polyester and Vinylester due to its chemical properties. Another difference is, Polyester and Vinylester uses the same hardener and as a result, the appearance between the two are similar, while epoxy tends to have a slight yellow or amber appearance. 125463There are many different categories of epoxy, so today we will highlight one of them; laminating epoxy.

1) The laminating system cures to a high strength moisture resistant plastic, with good physical properties.

2) The ratio is well suited for use with high-solids marine, maintenance coating and bonding agents.

3) The cure time is three days in the sun or a week if it is not. Set time changes with activator and film thickness.

4) If there is an excessive amount of activator applied , the laminating epoxy will be soft and rubbery. In contrast, if there is not enough activator, the epoxy will not cure hard.

5) The epoxy cures faster in high temperatures in thick layer applications.

Please note: additional recoating of this material is thoroughly cured. If the product has cured hard and tack-free, a light sanding and solvent wash is advisable before recoating.

 

An Intro to Liquid Urethane Foam

135434-sml

Our Liquid Urethane Foam is a two-component Isocyanate/Polyol base, with a pour-in-place system. The urethane apparatus is available in 3 separate density formulations by weight per cubic foot, which is displayed below:

  1.  2 quarts of 2 lb. foam will cover 2 cubic ft.
  2.  2 quarts of 4 lb. foam will cover 1 cubic ft.
  3.  2 quarts of 8 lb. foam will cover 1/2 cubic ft.

*Note: The 2 lb. foam expands the most whereas the 4 lb. & 8 lb. foam expands less.

One can discover the different categories for the use of liquid urethane foam:

  • Marine floatation
  • Art
  • Sculpting
  • Taxidermy
  • Prototyping
  • Mold Making
  • Decorative and Architecture
  • Millwork Pieces

When working with the foam, you will find: it’s resistance to mildew, mold, and solvent. The product also has impeccable durability attributable to it’s fantastic comprehensive strength. WOW! There is certainly a plethora of different purposes for Liquid Urethane Foam, and in addition to that; FGCI receives a number of questions concerning whether or not resin can be applied on top of the foam… We would like to mention that certain types of foam possess different temperature variations which can affect the application process, thus the system must be mixed correctly. If one were to mix in an excess amount of activator, the foam will become soft and spongy.   For more information on how to apply resin to foam, click here: Can I Apply Resin to Foam

Directions for General Small Quantity Use:foam

Step 1: Mix equal parts Base and Activator (1:1 by volume) or mix by weight (approx. 112 parts A-Side: Base to approx. 100 parts of B-Side: Activator).

Step 2: Mixing and metering equipment must accommodate the 1:1 by volume mix ratio.

Step 3: Mix thoroughly using a stir stick or a mechanical mixer. Please refer to Typical Reaction Profiles of Liquid Foam Chart for mix times.

Step 4: Pour immediately after mixing.

Step 5: Allow cooling between pouring.

*Directions may vary by application. For technical support and assistance with critical applications or large pours, please feel free to contact Customer Service at 1-800-272-7890.
