- Applications
Crystic Moldguard (B) has been specifically developed for the protection of composite molds when put into storage or for transportation. The cured coating has been designed to give easy stripping from stored molds prior to re-use.
- Formulation Guidelines
- Crystic Mouldguard (B) should be allowed to attain workshop temperature (18ºC - 20ºC) before use. Stir well by hand, or with a low shear mixer to avoid aeration, and then allow to stand to regain thixotropy. Crystic Mouldguard (B) requires only the addition of catalyst to start the curing reaction. The recommended catalyst is Butanox M50 (or other equivalent catalyst), which should be added at a level of 2%. (Please consult our Technical Service Department if other catalysts are to be used). The catalyst should be thoroughly incorporated into Crystic Mouldguard (B), with a low shear mechanical stirrer where possible.
- Crystic Mouldguard (B), mold and workshop should all be at, or above, 15ºC before curing is carried out.
- Application Guidelines
For normal requirements, the application of Crystic Mouldguard (B) should be controlled to 0.5 - 0.6mm (0.020 - 0.024 inches) wet film thickness. As a guide, approximately 600-700g/m² of Crystic Mouldguard (B) (depending on pigment) will give the required thickness when evenly applied.

Technical Details & Test Data
- Removal of Crystic Mouldguard (B)
- In order to strip off the coating the mold should be cleared of any water and accumulated debris. The mold should then be brought into the workshop and allowed to reach ambient temperature prior to the start of removal in order to reduce the risk of condensation on the actual mold surface. The coating should be initially released from the complete perimeter of the mold edge. Stripping should take place by applying an even force and pulling the coating consistently across the surface of the mold. Once removed the coating can be rolled up for disposal as due to its flexibility it should not generate sharp edges.
- Additives
- Crystic Mouldguard (B) is supplied in a restricted range of colors. This eliminates the potential for mixing errors with small quantities of pigment paste. The addition of fillers or pigments can adversely affect the properties of the cured product.
Packaging & Availability
- Packaging Type
- Regional Availability
- Packaging
- Crystic Mouldguard (B) is supplied in 25kg containers.
Storage & Handling
- Storage
- Crystic Mouldguard (B) should be stored in its original container and out of direct sunlight. It is recommended that the storage temperature should be less than 20ºC, where practical, but should not exceed 30ºC. Ideally, containers should only be opened immediately prior to use.
