How can I obtain smooth surface on the Parabeam(r) laminates like the smooth surface on your samples?
The smooth surface of the samples requires a smooth waxed mold, i.e. glass or melamine. In order to obtain a smooth surface on both sides, you can apply a second waxed mold (clamp mold) onto the wet Parabeam, taken into account the thickness of the fabric.
How can I be sure that the fabric is completely impregnated?
You can easily tell by the level of transparency if the Parabeam has been wetted out properly. Avoid oversaturated areas (inclusions) by simply rolling the excess resin to the edge- and out of the fabric. This will leave the right amount of resin remaining in the fabric.
How can I avoid a print-through on the gelcoat?
• For most applications, a simple veil or layer of CSM is sufficient.
• For more critical visual applications, you can use a print-blocking barrier coat.
• Another way is to let the outer skin cure before adding Parabeam.
How can I add more layers and other materials to the Parabeam® fabric?
You can apply other materials (csm, roving, foam etc) wet on wet on the Parabeam® fabric. Up to 3 mm glass can be rolled on wet Parabeam® before the end of the gelt-time and the full spring-back force will be guaranteed. After the gel-time layers of superior thickness can be laminated.
How to apply decorative laminates (e.g. HPL Prints) on the Parabeam® fabrics?
Decorative laminates can be used on the mould-side and the fabric is laminated directly on top of the laminate or the decorative laminates can be rolled over the wet Parabeam® fabric.
How to make an angle or curve with Parabeam?
One advantage of Parabeam is that it is fully shapeable and drapeable.
Simply fold the fabric in the desired angle or curve in the mold and roll well.
How can I color the Parabeam® laminate?
By coloring the resin (adding a pigment to it)
How can I ensure the translucency of the Parabeam® laminate?
The translucency is a result of the color of the resin, contact your resin supplier.
What is the reason of the rising (spring back) capacity of the Parabeam® fabric?
Parabeam 3d Glass Fabrics are cleverly designed around the natural qualities of glass. Glass can be ‘bent’ but cannot be ‘creased’. Imagine all those springs throughout the laminate pushing the decklayers apart, the resin stimulates this action (also called capillarity).
How can I avoid damages in the surface quality of the fabric (wrinkles and folds in the decklayers)?
Storage is important for the ensurance of the quality: stock the rolls horizontally in a dry environment at normal temperatures, unroll the fabric evenly and do not fold the fabric.
• Folds: you can remove folds by easily sliding the roller away from the fold when rolling next to it
• Wrinkles: rolling gently over the wrinkle will simply cause it to disappear
The fabric does not cure well enough, what should I do?
Two possible solutions:
1) When working with resins containing styrene, the entrapment of volatile styrene with the impregnated Parabeam® could cause cure inhibition. A low(er) styrene emission (LSE) type of resin or alternatively the addition of a styrene emission reducer (e.g. Byk S-740 for polyester and Byk S-750) to the resin is recommended.
2) To compensate the low masses of resin and therewith decreased curing temperature in the vertical pile threads, a highly reactive cure is recommended. This can be achieved with an increased catalyst level and with an increased level (preferably Cobaltoctoate) compensated with an inhibitor to set the gel time.
