Gluing with 2-component glue and fiberglass

Important when gluing with 2-component glue

2-component adhesives are all adhesives that you must and may only put together shortly before use. As soon as the adhesive is mixed, a chemical reaction begins, the adhesive becomes more and more viscous, until it is no longer usable after the so-called pot life. For reinforcement, you can embed fiberglass when gluing.

• For your own safety, wear gloves when handling these adhesives. Avoid contact with the eyes or mouth. Pay attention to children and pets, neither the little fingers of the little ones nor the paws of the animals should be able to get to the material.
• In general, 2-component adhesives consist of a binder, usually epoxy resin, and a hardener. Note that the binder remains sticky and sticky and hardly hardens without the hardener. Drops from the binder are difficult to remove and are very sticky.

• The hardener ensures that the binder hardens, it sets a chemical reaction in motion. Note that the hardener is corrosive.
• Only touch the glue when you need it, i.e. parts that you want to glue are degreased and roughened. The pot life of some 2-component adhesives is only a few seconds.

• Always read the exact instructions for use with these adhesives. Mix carefully in the mixing ratio mentioned there. Please note: If you use too little hardener, the resin remains sticky, if you use too much, the adhesive becomes brittle and caustic hardener can be left over.
• Expect strong warming when setting. For this reason, do not work in the blazing sun or in extreme heat.

If you want to incorporate fiber optics, further protective measures are required.

Glass fibers and fleece for bonding

You do not need fiberglass for most bonds, these only make sense if you have one, for example Want to bridge a gap or build a component from a composite of fiberglass and 2-component adhesive want. Pay more attention to your safety with fiber optics. You can also use polyester mats or fabrics for many purposes, which is preferable to fiberglass.

• Fiberglass is made up of tiny fibers of glass. When you cut, break, or tear the material, microscopic pieces of glass are created. These are so small that they can be easily inhaled. The glass particles do not decompose in the lungs, you have tiny shards of glass in your lungs. Therefore, always wear a dust filter mask when working with fiberglass.
• The cut edges of fiberglass or fleece consist of tiny glass splinters that easily penetrate the skin. It is therefore essential to wear protective gloves. Normal latex gloves are sufficient to protect against both the 2-component adhesive and the glass fibers.

Bonding with fiberglass and 2-component adhesive

1. Put on the gloves. Thoroughly degrease the parts that you want to glue.
2. Put on respiratory protection. Cut the fiberglass fabric.
3. Mix the 2-component adhesive. Apply a layer of the glue with a brush. Use the brush to press the fabric into the fabric. Apply another layer of glue to cover the fabric.
