- Features and Benefits
Solid Surface is produced from Crystic 935PA mixed with Aluminum Tri-Hydrate and polyester chips, using either continuous or batch mixing equipment fitted with a vacuum facility. Whilst it is not essential, optimum processing conditions use vibration on the molds when the resin mix is being cast.
- Solid Surface is homogeneous throughout so can easily be machined, polished and repaired during production or in service. i.e. scratches can be polished out and holes filled and abraded back
- The use of vacuum and vibration eliminates the introduction of air bubbles and enables the surface to be successfully abraded and polished, if required.
- Inclusion of Poly Stone chips allows different esthetic finishes to be achieved
- Using ATH as the filler provides translucency to the Solid Surface, imparts fire retardancy and offers resistance to most cleaning chemicals.
Applications & Uses

- Composites Processing Methods
- Recommended Applications
Applications using Crystic 935PA include high performance sanitary ware, vanity units, worktops and cladding panels in kitchens, bathrooms and commercial premises.
- Formulation Guidelines
Crystic 935PA should be allowed to attain workshop temperature (18°C - 20°C) before use. The recommended catalyst is Butanox M50 which should be added at 2% based on the resin content.
Recommended formulations for the casting of Crystic Stonecast Solid Surface are shown below:

Regulatory & Compliance
- Approvals
Fully cured Solid Surface based on Crystic 935PA meets the following criteria:
- Tested by FIRA to BS EN438. 1991 (Full certificate available on request)
- Class I rating to BS476 Part 7 1987

Technical Details & Test Data
- Post Cure
For optimum properties, Solid Surface should be post cured before being put into service. The Solid Surface should be allowed to cure for 24 hours at 20°C and then be oven cured for 3 hours at 80°C

Packaging & Availability
- Packaging Type
- Packaging
- Crystic® 935PA is supplied in 25kg, 225kg and 1 ton containers.
Storage & Handling
- Storage
- Crystic® 935PA should be stored in the dark in suitable closed containers. It is recommended that the storage temperature should be less than 20°C where practical, but should not exceed 30°C. Ideally, containers should be opened only immediately prior to use.
