What is AplTec (TM) composite patch?

AplTecTM composite patch is an universal composite repair system. Hardens fast in the coldest weather, in high humidity, under the rain or even underwater. AplTecTM composite patch is a permanent structural and fast repairs that bonds to virtually any surface.

Quand puis-je utiliser AplTec (TM) composite patch?

You can use AplTecTM composite patch in any weather conditions, from warm temperatures to freezing conditions. It works also under rain and snow. AplTecTM composite patch bonds composite parts, but also iron, aluminum, wood and most other material.

Can I use all the references underwater?

Yes, all AplTecTM composite patch references can be use underwater.

How does temperature affect AplTec (TM) composite patch?

Higher temperature will make AplTecTM composite patch system harden faster. Please check technical data sheet available to know relation between temperature and gel time

What are the main differences between glass range and carbon range?

Glass range AplTecTM composite patch and carbon range AplTecTM composite patch main difference is the mechanical properties – as a general rule, you get twice the tensile strength for a same gr/m2 reinforcement if you use carbon fibre compared to glass fibre. For impact/puncture though, the glass fibre will resist more than carbon fibre.

Please check the technical data sheet available online to know the properties for each
reference.eet available online to know the properties for each reference.

How do I choose the right patch for my application?

First you need to choose between glass fibre and Carbon fibre: if the weight issue is critical, choose carbon fibre.

Second, you need to choose the fibre type according to the type of geometrical structure you are prone to repair:

  • For flat surfaces: choose the Quadriaxial type: fibres orientation is equilibrated with 4 layers of fibre oriented at +45º/-45%/0º/90º. Like this the strength of the patch is equal in all directions.
  • For complex shapes: Choose the Biaxial fibre. There are two layers of fibre, oriented at +45º/-45º and this enables the patch to easily follow complex shapes.
  • For straight shapes, choose the Unidirectional fibre that is oriented all in the length direction (or 0º), all the strength of the fibre will work in one only direction (for masts, repairs, booms, beams, chassis frames…etc..)

If you are not sure of the type of shape you may need to repair, choose the Biaxial type as standard patch.

AplTec (TM) composite patch nomenclature, how does it work?

AplTecTM composite patch range is divided between glass and carbon references. Glass
references code start with G and Carbon references codes start with C. The number
that follow increases with the gramage (grams per square meter).
