MMA Flexible Base Coat

CP215 is a flexible modified MMA resin base coat based on PUMA technology.

CP215 is a flexible resin binder intended for the formulation of flexible membranes and flexible, wear resistant coatings exposed to subzero temperatures. It is mainly used for:

  • Waterproofing and shock absorbing membranes.
  • Flexible floor coverings especially if exposed to low temperatures (e.g. coolers and freezers).
  • As a wearing layer for outdoor applications exposed to heavy mechanical loadings and rapid temperature variations (i.e. ramps, bridges and car parks).
  • Flexible and crackbridging at low temperatures
  • Wear/impact resistant formulations possible
  • Easy to apply
  • Fast curing even at low temperatures
  • PUMA technology - free from external plasticiser

Surface Preparation

  • The area to be coated, must be pre-treated with an appropriate TREMCO primer (e.g. CP150 MMA Concrete Primer) including sanding.
  • The substrate must be dry, firm, solid and free of dust, fat and oil.
  • All bond breaking substances should be removed.


  • Prior to use CP215 must be carefully stirred to achieve a uniform distribution of the paraffin contained in the product.
  • CP215 is thoroughly mixed together with the TREMCO CP510 MMA Initiator (50% dibenzoyl peroxide), in accordance with the below guidelines.
  • Ensure the product is mixed using a suitable non-sparking/ATEX mixer.

It should be noted that the amount of catalyst powder to be added depends upon the temperature:
at 30°C add 1% by weight of resin
at 20°C add 2% by weight of resin
at 10°C add 4% by weight of resin
at 0°C add 5% by weight of resin
below 0°C add 5% by weight of resin

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

The material consumption and application method depends in which of the TREMCO MMA systems CP215 resin is being used for; see specific System Data Sheets for further information.
