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.

 

Our 3 to 1 Epoxy Activator forms an easy to use 2 component 100 % solids epoxy system when mixed with either of our available epoxy resins in a ratio of three parts Resin ( A side ) to one part Activator (B side ) by volume. It Is significantly faster setting then our 2 to 1 system with improved chemical and solvent resistance and generally improved physical properties. When mixed with our Standard Epoxy Resin it forms a thicker high viscosity system more suited to adhesive bonding and casting applications as it will generally form a tougher stronger plastic with better adhesion and very good resistance to hydrocarbon fuels and ethanol. When used with our Laminating Epoxy Resin it will form a thinner liquid more appropriate for wetting out fiberglass and other reinforcements it will have a slightly longer Gel Time and form a plastic with more flexibility, slightly less solvent resistance and lower HDT. Both systems cure to a tough, hard, blush free, amber colored plastic, with good physical properties, chemical and solvent resistance, excellent resistance to water and good adhesion to wood, glass, metals, and most other plastics.

As with all adhesive compounds bonding surfaces should be clean and free dirt or grease.

  Our 5 to 1 Laminating system is a two component 100 % solids Epoxy resin system designed for coating, bonding, and the lamination of glass, carbon, or kevlar fibers as used in the production of composite plastic products. This material features an easy to use 5 to 1 by volume mix ratio that is (5 Parts Epoxy Resin to 1 Part of Activator by volume such as liquid ounces, pints, quarts, or liters). The material itself features easy wet out, rapid cure, and good adhesion to a variety of materials including wood, glass, metals and most other plastics. The material cures to a very rigid, hard, amber colored plastic, with a high Heat Distortion Temperature and will have good physical properties, good resistance to water, and excellent resistance to chemicals and solvents. Thin films cured in open air may blush . 
As with all adhesive type compounds proper surface preparation is essential for good bond strength, recoating of the material should be accomplished before the material is fully cured after which sanding and solvent wash may be necessary for good secondary bonding.
