Wilsor Epoxy Impregnation Set

Application

Epoxy resin is a high-quality, clear resin, strong and wear-resistant. Adheres to practically any surface, but does not affect that surface (eg polystyrene foam), as is often the case with polyester resin. Epoxy resin does not shrink when cured. Warping due to shrinkage does not occur.

Epoxy Resin Compared To Polyester Resin

Benefit

• No shrinkage
• good adhesion
• strong and tough

Disadvantage

• Price
• Mixing ratio matters
• Slower curing

adhesive strength

Epoxy resin adheres well to almost anything. Think of gluing wooden boats together. It holds the fibers of the glass fabric well and is partly because of this so strong. Due to this tough strength, it is often used in surfboards, skis, model airplanes as well as real airplanes, etc.

Instructions

• Sand the damaged part and make sure it is dry, free of dust and grease.
• Add both components in a mixing bowl. The ratio harder/resin is 1 to 3 (for example: resin 300gram and harder 100gram). Too much or too little hardener gives an uncured end result. Processing time depends on the temperature and the amount produced. At 100 gr and 20C it is about 30min. Larger amounts and higher temperatures shorten the processing time. Heat is released once resin and hardener are mixed.
• Apply a thin coat of epoxy with a brush, then apply the glass cloth and tampon it until it becomes translucent. Apply the next layer of glass fabric until a sufficiently thick layer has been built up.
• If epoxy over a cured epoxy layer is required, it must first be well sanded.

Glass fabric or carbon(carbon fabric)

If the epoxy is exposed to high tensile strength, the epoxy must be provided with a reinforcement material such as a glass fabric mat. This mat consists of very thin glass filaments bundled and woven into a flexible mat.

PLEASE NOTE: Glass chopping mat in which the glass wires are glued on top of each other in an unordered way contains an adhesive around each glass wire. This glue does not dissolve in epoxy resin, which is why glass cutting mat is not recommended when used with epoxy resin
