Method of Application

• The TREMCO MMA system to be sealed must be dry, clean, free from dust and grease.
• Any fresh base coat must be completely cured.
• For broadcast systems all loose aggregate or flakes must be thoroughly removed prior to applying the CP930.

Mixing

• Prior to use, CP930 must be carefully stirred to achieve a uniform distribution of the paraffin and fillers contained in the product.
• Add 10% by weight, or as otherwise directed by tremco illbruck technical services, CP935 micronised pigment in the required colour and mix thoroughly until uniformly distributed.
• CP935 is thoroughly mixed together with the CP935 MMA Initiator (50% dibenzoyl peroxide), in accordance with the below guidelines.

It should be noted that the amount of catalyst powder to be added depends upon the temperature.
- at 30°C add 180 g of catalyst to each 22 kg pail
- at 20°C add 360 g of catalyst to each 22 kg pail
- at 10°C add 540 g of catalyst to each 22 kg pail
- at 0°C add 720 g of catalyst to each 22 kg pail

For eventual addition of filler or pigment on site, please contact our Technical Service Department for further details.

Note: Weight to Volumetric conversion of Catalyst.
1 cm³ of CP510 MMA Initiator  = 0.64 g
1 g of CP510 MMA Initiator = 1.57 cm³

Method of Application

• Immediately after the catalyst has been added and mixed, the sealer is spread onto the CP215 MMA Base Coat using a rubber squeegee and paint roller.
• For good results it is important always to work with freshly catalysed material (i.e. small batch sizes).
• Layer thickness must be kept within 0.6-0.8kg/m² on aggregated surfaces, 0.3-0.7kg/m² on non-aggregated surfaces.
