It provides excellent resistance to salt water, acidic and boat building epoxy optical exposure and retains its physical properties even after prolonged water immersion. It is the low viscosity version thinner of MAX BOND family of marine grade resin systems providing improved ease of use and faster fiberglass fabric wetting.

It is only diluted from the base epoxy and curing agent formulation to yield ease of use and general fabric impregnation. Over dilution of epoxy resin below cPs similar to the consistency of mineral oil are over diluted with lower functional epoxy diluents that will also dilute and lower the final cured mechanical strength. It is room temperature cured or opticzl cured for faster cure time.

Epoxy based polymers are one of the most versatile thermoset plastics boat building epoxy optical can be modified into a multitude of applications and fit very specific task as demanded by the application.

It offers ease of use and generally safer to handle over other types of thermoset resins which make it the choice material for many high-performance composites. New ideas demand new technology in material science and the skill to compose its constituent into a synergistic composite.

What is Impact testing? Impact testing is one bost the most revealing test methods that demonstrate boat building epoxy optical material's ability to resist and withstand a high-rate of boat building epoxy optical loading at a short amount of time.

Its behavior during and after the impact can define its epoxt mechanical property and conditional limits upon its destruction. Why is Impact Testing Important? The impact resistance of an object provides the ultimate measure of its resistance to its definitive destruction. With this knowledge, other aspects of mechanical performance can be accurately derived and through skillful engineering, one can determine the impact energies the part can withstand and design the construction that will resist such assaults boat building epoxy optical the projected lifespan.

It was also used as a coating to seal the wood, yielding a waterproof protective coating. Step 1. Ensure that the wood is as epocy as possible; any boat building epoxy optical moisture will be sealed boat building epoxy optical wood once it is coated with the resin.

Acetone Solvent. Purchase this epixy with any of our product offering and the shipping cost of the scale is free. Application Procedure. Allow the boat building epoxy optical coat to absorb for 10 minutes to allow the acetone boat building epoxy optical evaporate and then apply a second coat to ensure resin saturation. First coat will be readily absorb by the uncoated wood. Apply several coats consecutively to seal the wood porosity.

This will ooptical improve the buildig strength of the plywood by binding all the wood fibers into a unitized layer. Some 'grain-raising' may occur which can be sanded upon cure with fine-grit sandpaper and then re-coated. Pictures contributed by our actual customer who used the.

By resolute definition, a fabricated COMPOSITE material is a manufactured collection of two or more ingredients or products intentionally combined to form a new homogeneous material that is defined by its performance that should uniquely greater than the sum of its individual parts. With respect to the raw materials selection -fabric and resin, the fabricating process and the and curing and test validation of composite part, these aspects must be carefully considered and in the engineering phase of the composite.

Most fabrics are stronger in the warp than the fill because higher tension is placed on the warp fiber keeping it straighter during the weaving process. Rare exceptions occur when a larger, therefore stronger thread is used in the fill direction than the warp direction. Is a very simple weave pattern and the most common style. The warp and fill yarns are interlaced over and under each other in alternating fashion. Plain weave provides good stability, porosity epoxt the least yarn slippage for a given boat building epoxy optical count.

The eight-harness satin is similar to the four-harness satin except that one filling yarn floats over seven warp yarns and under one. This is a very pliable weave and is used for forming over curved surfaces. The four-harness satin weave is more pliable than the plain weave and is easier to conform to curved surfaces typical in reinforced plastics. In this weave pattern, there is a three by one interfacing where a filling yarn floats over three warp yarns and under one.

Twill weave is more pliable than the plain weave and has better drivability while maintaining more fabric stability than a four or eight harness satin weave. The weave pattern is characterized by a diagonal rib created by one warp yarn floating over at least two filling yarns.

Step Three:. Pre-lay-up notes. Mix the proper amount of resin needed and be accurate proportioning the resin and curing agent. Adding more curing agent than the recommended mix ratio will not promote a faster cure. Over saturation or starving the fiberglass or any composite fabric will yield poor mechanical performance. When mechanical load or pressure is applied to the composite laminate, the physical strength of the fabric should bear the stress and not the resin.

If the laminate is over saturated with the resin it will most likely to fracture or shatter instead of rebounding and resist damage. This is the optimum ratio used in high-performance prepreg or pre-impregnated fabrics typically used in aerospace and high-performance structural boat building epoxy optical. Place the entire pre-cut fiberglass to be used on a digital scale to determine the fabric to resin weight ratio.

Measuring by weight will ensure accurate composite fabrication and repeatability, rather than using OSY ounces per square yard or GSM grams per meter square data. Measuring by weight will ensure accurate composite fabrication and repeatability, rather than using Eposy data.

Typical fabric weight regardless of weave pattern. Ounces per square yard or OSY is also known as aerial weight, which is the most common unit of measurement for composite fabrics.

To determine how much resin is needed to adequately impregnate the fiberglass, boat building epoxy optical the following equation:. So for every square yard of 8-ounce fabric, it will obat Apply the mixed resin onto the surface and then lay the fabric and allow the resin to saturate through the fabric. This is one of the most common processing error that yields sub-standard laminates.

By laying the fiberglass onto a layer of the prepared resin, less air bubbles are entrapped during the wetting-out stage. Air is pushed up and outwards instead of forcing the resin through the fabric which will entrap air bubbles.

WOOD/EPOXY BOATBUILDING NEWS & BOAT BUILDING TECHNIQUES. Hi fellow boat builder, this is the start of our on line - BOAT BUILDING NEWS - which will be updated on a regular basis. We can only share with you a fraction of the information included in our BOATBUILDING E-BOOKS. With fiberglass boat building, however, the major components of the boat � the hull, deck, liner, and large parts like consoles�are molded from fiberglass. Usually, this means starting with a female mold. The mold is first sprayed with gelcoat, then fiberglass cloth is applied, and then resin is used to saturate or �wet out� the fiberglass. I�ve been building cedar-strip rowboats and canoes in British Columbia for more than 15 years. They are light, strong, and made of local woods: red and yellow cedar, fir, and maple. Until I discovered EcoPoxy about four years ago, the least appealing aspect of my work was the toxicity and odor of the petrochemical epoxy.
