FAQS


Is Aqua-Resin clear?
No, it is opaque, except in thin layers, where it is translucent like a piece of white paper.

Can Aqua-Resin be colored?
Yes, we have a line of color dispersions, Aqua-Color™
, available in red, yellow, blue, black and white. Various other materials may be added to alter color and appearance including mineral aggregates, dry pigments, colored flock, metal powders, etc. The use of acrylic paint and paint tinting colors for coloring Aqua‐Resin is not recommended if permanence is required. Cured Aqua‐Resin, can of course, also be painted; it accepts most paints with no problems.

Why do you need fiberglass to reinforce Aqua-Resin? 
Aqua‐Resin is what is referred to as a “composite” material, and as such is a combination of a high compressive strength matrix (the Aqua‐Resin mix) and a high tensile strength fiber (fiberglass). This combination of two material types results in an extremely strong, rigid, yet light-weight material. Aqua‐Resin without the fiber would need to be much thicker and would still have minimal break strength.

Isn’t fiberglass dangerous?
Not the fiberglass used in our fiberglass products. This is a relatively large diameter fiber, which, even when fractured, breaks into particles considered too large to enter deeply into the lungs where it might do some harm. However, in contrast, the fiberglass used in fiberglass insulation for home construction is a very fine filament glass. This type of fiberglass has a small enough diameter to enter deeply into the lungs and is therefore considered a possible carcinogen. None of our products contain this small diameter fiberglass.

Why do you suggest only Aqua-Resin brand of fiberglass products be used?
We suggest using our three fiberglass products, Aqua-Axial 2, Aqua-Veil and Aqua-Glass because conventional fiberglass such as fiberglass cloth, chopped strand mat and chopped fiberglass strands typically have a sizing on it that is only compatible with polyester resin, but will not dissolve in Aqua‐Resin. The fact that this non‐compatible sizing will not dissolve prevents full surface contact of the Aqua-Resin mix to the individual fiberglass filaments and therefore can result in less than optimal strength. This being said, if you do not require optimal strength, you can use conventional chopped strand mat or chopped fiberglass strand.

Why is  your Aqua-Glass Cut Glass Fiber provided in such long cut lengths? 
The two longer cuts, 3 ½-1” and 4 ½”, are intended as a principal reinforcing fiber in an Aqua-Resin laminate.  We find that fiber lengths over 3” provide substantially stronger laminates. Because of correct binder compatibility with Aqua-Resin mixes and their unusually long fiber lengths, they produce exceptionally stronger parts than would conventional chopped strand mat for instance.  The 3 ½-1” is used for laminates with tight curves and irregular geometry, while the 4 ½” is useful for rapid building of flatter areas or gentle curves. 

Your Aqua-Resin brand fiber glass products are often more expensive than conventional fiberglass. Are they worth the extra money?
Yes, especially regarding the longer fiber lengths, 3 ½-1” and 4 ½”, If you look at the total cost of a finished part, you will see that they save you money.  At the total recommended 8-10% fiberglass content, the extra cost of our fiberglass would admittedly add to the finished part cost. But because of the extra strength gained, you will easily find that required thickness would approximately be cut in half if you are comparing what you would need using chopped strand mat. At half the thickness, the savings in total finished cost would be in proportion.  You will have a lighter stronger less expensive part--also, with the additional saving in labor fabricating a lighter part.

What happens if the Lxf  Liquid is allowed to freeze?
Generally nothing. The L
xf  Liquid can withstand multiple freeze/thaw cycles before it becomes unusable. We guarantee a minimum of five cycles. Regarding our other products, none will suffer having been frozen. However, THX-6 and Aqua-Color, once thawed, should be re-stirred.

Is Aqua‐Resin heavy?
Cured Aqua‐Resin, itself is a fairly dense and therefore a heavy material. But its density contributes substantially to its strength, so that parts made with it can be quite thin, typically no more than 1/8” wall thickness. At this wall thickness, rather light weight parts are produced, so one may say that Aqua‐Resin is actually a light weight material.

Is Aqua‐Resin suitable for exterior use?
Yes, but certain precautions and procedures must be adhered to. Please contact us at info@aquaresin.com and request information on exterior use.

Do I need to use a scale to measure the correct proportions for mixing Aqua‐Resin?
Not usually, for most basic casting and laminating uses, measuring by volume is fine. If, however, for instance, you need to visually duplicate gel coat color on multiple pieces or insure consistent thermal expansion for exterior temperature extremes, then weighing is recommended.

Is power mixing necessary?
No, not necessarily. If you are doing non‐critical work such as a mold jacket or a rough textured surface, for instance, hand mixing is adequate. If you are formulating a gel coat or working in very thin layers, or need batch to batch consistency, then power mixing is recommended. The best mixing blade we have found for Aqua-Resin so far, is a spring-bowtie mixing blade, but in most circumstances any mixing blade works well.

What is the timing on the various cure stages with Aqua‐Resin?
The working time for a normal Aqua‐Resin mix is approximately 30 minutes, the set time is around 40 minutes and de-mold time from a soft rubber mold around 90 minutes.

What is the shelf life?
The shelf life for the L
xf Liquid Component, when stored at room temperature, is 2 years from date of manufacture. The S3 Powder Component, when kept from moisture in a sealed container, has proved to be stable and fully usable after many years. We have material over 10 years old that show no signs of deterioration.

What is the ASTM D‐4236 designation I see on all your labels?
By law, all art materials sold in the U.S. must bear the phrase "conforms to ASTM D-4236," confirming that they have been properly labeled for any chronic health hazards, in accordance with the federal Labeling Hazardous Art Materials Act (LHAMA). Under LHAMA, all art materials must be evaluated by an independent toxicologist to determine if any chronic health hazards do exist in the product. All our products have been evaluated; none of our products pose a chronic health risk.

How do I get technical help?
Aqua‐Resin is always happy to provide technical help. We do ask, however, that you read all relevant instructions prior to asking for help. Links to our instructions can be found on our PRODUCTS page by clicking on the product names. Very often your questions will be answered in these instructions. If not, please email us at info@aquaresin.com and please include a phone number if you like.

In viewing various online videos about Aqua-Resin, we find apparently conflicting and often confusing advice on technique and applications. How can we be sure we are getting the best advice?
