Our 300 LV system is a two component 100 % solids epoxy resin system designed for the lamination of glass, carbon, or kevlar fibers as used in the production of composite plastic products. This material features a forgiving and easy to use 2 to 1 by volume mix ratio that is ( 2 Parts Epoxy Resin side to 1 Part of Activator side by volume). The material itself features easy wet out, moderate pot life, and good adhesion to a wide variety of other common materials including wood, glass, metals, cured fiberglass composites, and most other plastics. The material cures to a hard, light colored plastic with good physical properties, and excellent resistance to water, chemicals, and solvents. This material may lightly blush in thin films or high humidity. Cure time for this material may be accelerated by mild heat up to 150 F. As with all adhesive type compounds, proper surface preparation is essential for good bond strength; additionally recoating of this material should be accomplished before the material is thoroughly cured, generally in less than 24 hours. If the material has cured hard or blushed, a light sanding and solvent wash may be necessary before recoating.

 Avoid using this product in direct sunlight.

 The ideal temperature for use of this product is 77°F. Best results for this product can be obtained at temperatures between 70°F and 85°F, in a clean, dry, dust-free environment.

 It is not recommended to wet out fiberglass over 1/8 in thickness. Use of more than 1/8 may generate excessive heat. Allow layer to tack up (but not fully cure) prior to pouring next layer.

 Boatyard Polyester Resin is a non-specified resin that contains different types of polyester resins and wax. Material may cure hard and tack-free due to wax. If so, product will need to be sanded prior to adding another layer in order to promote good bonding.

 This is an economical laminating resin for repairs on boats, small parts production, autos, etc. Not recommended for use below the waterline.

 If sanding is required to apply more fiberglass, use 36, 24, or 16 grit. Low grits will create deeper scratches to make the new layer adhere better to the existing one. Be sure to clean the surface before applying another layer.

 To apply gelcoat, prep the surface with 80 grit sandpaper. To apply primer, prep the surface with 220 grit sandpaper. To apply paint, prep the surface with 320 grit sandpaper.

Directions for Use:
Step 1: Choose the appropriate volume for your project. The type of fiberglass used will determine the amount of resin needed.
Step 2: Make sure to agitate or stir the product thoroughly before use.
Step 3: Mix 1 to 2% MEKP, in resin solution thoroughly. Please refer to Catalyst Concentration Chart for quantities.
Step 4: Thinner fiberglass can easily be wet through. To thoroughly wet out heavier materials, apply resin first to one side, then flip the glass over to wet out the other side. Use paint-style rollers to distribute resin quickly.
Step 5: Roll each layer with a glass roller to remove air. The fiberglass will go completely transparent when it is adequately wet.
Step 6: Add sanding aid (Product #123833) to the final coat to allow a full cure and a tack-free surface. Refer to Sanding Aid Chart for quantities.

This resin was designed for mass casting applications where the volume of the project needs to be stress free and crack resistant. This water clear casting resin meets the need where the low exotherm and long gel times are required to provide successful results. The ideal working temperature is at 77°F. Best results for this product can be obtained at temperatures between 70°F and 85°F, in a clean, dry, dust-free environment. FGCI’s Clear Casting Resin is a polyester resin for ambient temperature cure with MEK-P. It is used to produce medium to large size castings with great clarity. FGCI’s Clear Casting Resin was designed to reduce the appearance of cracks in larger castings with a long cure time, low peak exotherm, and minimal shrinkage. If sanding is required, use 320 grit. Be sure to clean the surface before applying any additional layers.
