450gsm Chopped Stand Mat (CSM) – Powder Bound

Pack Type: Per Metre | 4m Pack | 10m Roll | 20m Roll

Chopped strand mat builds thickness and bonds layers together. Combine with reinforcement layers to build strength in your laminate.

Features:

  • Powder bound – compatible with epoxy, polyester and vinyl ester
  • 450gsm CSM is a good general purpose mat adding 0.4-0.5mm (approx) per layer
  • Shapes well around curves and irregular areas once wet out
  • Commonly used in building plugs for moulds due to its balance of speed to build up and ability to be shaped

Technical Snapshot:

  • Fibre type: E‑glass
  • Binder: Powder bound
  • Weight: 450gsm
  • Width: 1000 mm

Quick Tips:

  • Dry cut CSM before mixing up your resin to avoid sticky gloves, wasted time and a messy lay up.
  • Wet out one layer at a time and apply next layer while wet.  For thicker laminates, build in stages (typically 2-4 layers at a time) to avoid excess heat when the resin cures.
  • Choose the right weight of CSM for each part of your build;
    • 100gsm – acts like a surface tissue
    • 225gsm – gives controlled layering
    • 300gsm – conforms well to curves and details
    • 450gsm – balances build up speed and conformability
    • 600gsm – builds thickness quickly but is stiffer

A few words on safety:

  • Glass fibres will irritate your skin and lungs.  Wear gloves, long sleeves and mask when handling and sanding
