General Purpose Polyester Resin, Gallon
Product Description
General Purpose Polyester Resin Gallon used.Ideally with fiberglass mat, cloth, roving, or stitch mats. Designed to be thin enough for easy wet-out. Excellent for molding new parts & repairs.
Size: Gallon
Included: 2 Ounces of MEKP
Tips:
- General purpose resin is excellent for laminating with fiberglass, kevlar and carbon reinforcements.
- Pigment can be added to this resin, but the maximum is 3%.
- The ideal temperature is at 77° F. Best results for this product can be obtained at temperatures between 70 and 85 degrees F, in a clean, dry, dust free environment.
- The thinner the fiberglass, the less chemical reaction you will have. The thicker the fiberglass the less hardener you will need because you will generate more heat and have more chemical reaction, but never go below 1%.To get a complete cure, you will need to add sanding aid to the resin or spray PVA over it, while it is still hot.

Directions for Use:
Step 1: Choose the appropriate volume for your project. The type of fiberglass materials used will determine the amount of resin needed.
Step 2: Make sure to agitate or stir the product thoroughly before use.
Step 3: Mix in 1 to 2% MEKP. 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 Wax Sanding Aid to the final coat to allow a full cure and a tack-free surface. Refer to Sanding Aid Chart for quantities.
- Avoid using 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 generally 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 adding additional layers.
- General Purpose Polyester resin is a standard grade of a formulated product. This unsaturated polyester resin is designed to wet out the glass reinforcement rapidly without drainage. The rapid wetting will save time in laying up laminates.
- This is an economical resin, designed for hand lay up of boats, panels and other industrial fabrication of demanding quality.
- If sanding is required to apply more fiberglass, use 36, 24 or 16 grit. Low grits will create deeper scratches, allowing the new layer to adhere better to the existing one. Be sure to clean the surface before applying another layer.
- To apply gelcoat over the resin, 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.
