Description
CM STAYWHITE is a single component silicone sealant which when exposed to atmospheric humidity cures rapidly to form a permanent flexible and extremely durable weather tight sealant. The cured sealant has a good movement accommodation factor throughout a wide temperature range, resistance to mould and bacterial growth.
MICROTEC Silver nano antibacterial technology a powerful additive which prevents black mould,mildew and bacterial growth.
CM STAYWHITE bonds strongly to clean uncoated glass, ceramic or painted surfaces without the need for a primer. For most other substrates it is recommended that CM Multi wipes be used to ensure optimal bonding.
CM STAYWHITE should be used on applications where joint loads are high and where relative movement between substrates is minimal. Packaged in a recyclable grade 310ml cartridge it is ready for immediate use after cleaning surfaces with CM Multi wipes.
CM STAYWHITE meets the requirements to BS5889 {Type B} and US Fed Spec TTS 001543A (Class A) and TTS 00230C (Class A)

Preparation of surfaces
Thorough preparation is essential.
The joint should be completely dry and free from all traces of dirt, dust, grease and any previous sealants or other foreign matter.
All joints should be clean, dry and oil free.
In all cases a clean bonding surface must be obtained.
Following preparation of section joints place into the base of the joint a bond breaker or back up foam to form the correct cross section for the joint sealant bonding to the base of the joint.
Cleaning
After cleaning the joint it should be wiped with CM Multi Wipes care being taken to ensure complete coverage. Allow Five minutes after wiping for the solvent to evaporate. It is important for optimum performance of CM STAYWHITE that CM Multi Wipes are used
Application
- Cut off top of the cartridge just above nozzle thread
- Screw nozzle into place and cut the nozzle to the required size at an angle of 45 degrees.
- Apply by gun – place the nozzle angle flush to the joint and extrude a continuous bead of CM STAYWHITE into the joint.
- Move the nozzle along the joint while extruding.
- Adequate contact between CM STAYWHITE and the substrate must be ensured to eliminate the possibility of adhesion failure.
- After sealing release gun pressure
Surface and Edge Finishing
The edges of joints must be kept clean and to a neat line by use of masking tape. This masking will protect the surface adjacent to the joint and should be removed after application of CM STAYWHITE and before it has set
NOTE:
Lower temperatures retard cure.
DO NOT APPLY CM STAYWHITE AT TEMPERATURES BELOW 5’C.
Does not cure well in arid conditions.
Cleaning of Tools
Tools should be cleaned after use with CM Multi Wipes
Care of Product
Cured silicone should to cleaned with fresh clean water at least once a week to help maintain its pure white colour. If silicone is damaged it should be cut away and re-jointed
Limitations
- Do not use as a Aquarium silicone
- Not intended as a exterior use
