Epoxy-Based Gel Coat Recommendations

[ahender]

Can anyone recommend an epoxy-based gel coat?

I have found one and it only comes in red.

Thanks...Alan

Yes, what do you plan to do with it?

[ahender]

Use it as the first coat in a female mold.

You can get it at Composites One.

DESCRIPTION:
IMEDGE® ECT120 coatings are advanced Epoxy Compatible Technology (ECT) products that have been formulated to be used as in-mold, exterior coatings for reinforced plastic parts. Unique benefits of IMEDGE® ECT120 coatings are
��
Excellent adhesion to epoxy matrix laminates
��
Deep, dark, rich, high gloss colors
��
Excellent color and gloss recovery after sanding and buffing
��
Blush resistant
��
Excellent weathering resistance.
��
Enhanced impact resistance and toughness for reduced cracking
��
Excellent scratch and wear resistance
��
Resistant to porosity
��
Low weight per gallon
IMEDGE® ECT120 coatings are formulated to meet EPA’s National Emission Standards for Hazardous Air Pollutants (NESHAP) for both Boat Manufacturing and Reinforced Plastic Composites products.
IMEDGE® ECT120 coatings offer exceptional water resistance and durable and crack resistant. While offering these benefits, IMEDGE® ECT120 coatings have retained the important construction and application qualities expected from CCP coatings, such as resistance to tearing and color separation, sag resistance, consistent liquid properties, and more. These all add up to higher quality appeal in FRP parts made with CCP IMEDGE® ECT120 Series products.

TYPICAL PROPERTIES (at 77°F):
Typical properties of IMEDGE® ECT120 are shown below. These values may or may not be manufacturing control criteria. They are listed for reference only. Particular batches will not conform exactly to the numbers listed because storage conditions, temperature changes, age, testing equipment (type and procedure) can each have a significant effect on the test results. Products outside of these readings can perform acceptably.

Refer to the MSDS for handling precautions. MSDS’s will be supplied automatically with the first order for material, and are available by product code upon request from CCP’s Regulatory Department or on CCP’s website at www.ccponline.com.
APPLICATION:
IMEDGE® ECT120 must be mixed prior to use. This includes prior to production spray application and when obtaining material for patching or any material that has been set aside for patching. When not agitated, IMEDGE® ECT120 develops a viscous layer at the top of the container. The material at the bottom of the container is much lower in viscosity. Material applied in this condition is likely to sag and have porosity. Mixing of IMEDGE® ECT120 is critical to success with the product.

Excellent! Thank you.

Unfortunately they recommend spraying only.

Do not want to get into that.

[ondarvr]

Spraying is recomended, but brushing works, the directions are for production shops.

[ahender]

Thanks again.
