121 Marine Grade Epoxy Resin Kit For Laminating and Repairs
Our 1 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 a forgiving, easy to use, 1 to 1 by volume mix ratio (1 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, long pot life, and good adhesion to a wide variety of materials including wood, fiberglass, glass, metals and most other plastics.
The material cures to a hard, slightly flexible, blush free, Clear colored plastic, having good physical properties, chemical and solvent resistance, and excellent resistance to water. It may be painted after curing. (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 re-coating of this material should be accomplished before the material is thoroughly cured generally in less then 24 hours. If the material has cured hard and tack free a light sanding and solvent wash may be necessary before re-coating.

Tips For Cleaning Epoxy
Epoxy resin is a powerful adhesive that typically comes in two parts: resin and the hardener. Over time epoxy resin can become discolored, either from age or from being in sunlight too often. Sunlight damage is much harder to remove as the discoloring is usually in the entire layer of epoxy. Surfaces blemishes are among the most common and will create an unsightly appearance, but it can be cleaned. This article will share tips on how to clean epoxy resin.
1) Buffing and Scrubbing
- When you begin to clean the epoxy resin only use a very soft towel and buff the surface with mild force or speed.
- With enough strength and friction, you can cause the epoxy resin to heat up and then soften so be careful.
- If the stain is textured or a food particle is stuck on it, then you may lightly scrub the epoxy resin with a brush that has a soft bristle to remove the particle. Be careful not to use anything too aggressive, or you may ruin the finish.
- Finish by buffing the area dry.
2) Discolored Epoxy Resin
- Any items left out in the sunlight will fade and create a permanent brownish tan color which cannot be cleaned or removed.
- Surface blemishes can be cleaned with bleach. Use small amounts of bleach with a cotton swab to remove the discoloring. Caution - Do not use straight bleach, too much can cause the epoxy resin to soften. This process may need to be repeated, depending on how bad the discoloration
3) Steam Cleaning
- Epoxy resin is resistant to water. Most stains once heated and water applied, will loosen and be able to wipe away
What is the proper storage and shelf life of Epoxy?
You should store your epoxy resin and hardener at room temperature and keep in containers closed to prevent contamination. With proper storage, resin and hardeners should remain usable for many years. After a long storage, you can mix a small test batch to assure proper curing, before using it on a large project.
Hardeners may darken with age, but physical properties are not affected by color. If clear finishing, be aware of a possible color shift if very old and new hardeners are used on the same project.
If opened, the epoxy has a 6-month shelf life if stored at room temperature in a closed box.
Can I use the epoxy in cold weather?
As long as the epoxy is warm.
If the epoxy resin gets cold, it will crystallize. As a result, it will be difficult to dispense or mix.
To bring the resin back to a usable state warm the bottles and contents. This can take several hours. The best method of warming the epoxy components is by plunging the containers into hot water.
When you are done working be sure to place it in a warm place.
Common jargon used with epoxy; common words and lingo
Abrasion Resistance: The ability to withstand the effects of repeated wearing, rubbing, scraping, etc.
Cure: To change the physical, chemical, or electrical properties of a material by chemical reaction, by the action of heat and catalysts alone or in combination, with or without pressure. Specifically to convert a low molecular weight polymer or resin to an insoluble, infusible state.
Density: Weight per unit volume of a given, the degree of compactness of a substance
Epoxy Resins: any of a class of solid or semisolid viscous substances obtained either as exudations from certain plants or prepared by polymerization of simple molecules
Mat: A randomly distributed felt of fibers, usually glass, used in reinforced plastics.
Seal Coat: The seal coat is a small batch of epoxy that is brushed on in a thin layer to seal any pores in the surface and prevent air bubbles from forming in the following flood coat.
Flood Coat: A flood coat is simply poured on the surface and it self-levels to 1/8". Flood coats are applied in 1/8" layers at a time, as many as desired can be applied.
Pigment: A color material (especially a powder to be mixed with a liquid to produce paint)
Viscosity: Resistance of a liquid to shear forces
Ripples: warping or imperfections
