100g Emulsion Bound Chopped Strand Mat (1250mm)

Ultra-light weight 100g fibreglass matting chopped strand mat ideal for use as a fine surface layer on composite moulds before the main reinforcement is laid down.

Unlike simply stripped apart a heavier glass mat, this special 100gsm lightweight fibreglass matting has much finer glass strands making it very easy to lay the mat down in intimate contact with the gel coat, significantly reducing the chance of any voids or air bubbles between the gel coat and the main reinforcement.

This mat is 'emulsion bound' which means it uses a binder that is broken down by polyester or vinylester resin. It is not recommended for use with epoxy resin although at this very light weight it would be possible to laminate this mat using epoxy resin.

Typical Uses

Our 100g emulsion bound CSM is suitable for use with polyester and vinylester resin systems. For an epoxy compatible CSM please see our powder bound CSM.

• Recommended reinforcement (use 2 layers) for the coupling coat in our Uni-Mould system
• Polyester and vinylester compatible
• Suitable for mould making and laminating
• Suitable for use with our Uni-Mould universal mould making system

How to Buy

This roll is 1.25m (49") wide and the mat is sold by the linear metre. The unit price shown is for 1 linear metre but volume discounts automatically apply for larger quantities of mat.

Please purchase the number of linear metres you require. When purchasing multiple metres, for shorter lengths, the fabric will be supplied folded to keep package size and hence shipping costs down. If you need your fabric on a roll for a specific application then please contact us and we will be more than happy to supply it that way. For larger lengths, the fabric may be supplied in two or more pieces.

A minimum order quantity of 3m applies to this product.

Further Information

Use with Uni-Mould

This special 100g mat is highly recommended as the reinforcement for the 'coupling coat' when using our Uni-Mould universal mould making system. Using 2 layers of this 100g mat will result in 200g of reinforcement for the coupling layer which is the perfect amount and the fine strands of glass in this light weight mat will ensure that the coupling layer is entirely void free.

Emulsion Bound CSM

This 'emulsion bound' CSM is designed for use with polyester resin or vinylester resin which will quickly break down the emulsion binder so that the mat can easily be laminated by brush or roller to follow the contours of the mould.

Emulsion bound CSM is not really suitable for use with epoxy resin because the emulsion binder will not be broken down by epoxy, making the mat almost difficult to laminate with.
