CP365 is a medium viscosity, urethane-modified, pre-reacted 100% solid membrane system based on acrylic monomers. To initiate curing, just add CP510 MMA Initiator.
CP365 is designed as a liquid applied, low modulus waterproofing membrane and coating. It can also be used as a joint filler for joints with low dynamic movements.
The cured product is a very flexible crack-bridging membrane that retains its flexibility and crack-bridging performance in service even when the temperature reaches –30°C.
The domains of application for CP365 include:
- As a bridge deck waterproofing membrane, onto which rolled asphalt at temperatures up to 250°C can be directly applied.
- For the sub-grade waterproofing of buildings and civil engineering structures, including underneath ground slabs.
- The waterproofing of concrete and metal railway bridges including directly under track ballast.
- The waterproofing of pedestrian and vehicular trafficked areas (balconies, car parks, etc.)
- The protection and waterproofing of stadium terracing.
- The waterproofing of tunnels, channels and dam structures.
- The waterproofing of containment structures including reservoirs and waste and contaminated material storage structures.
- As a joint filler for joints with low dynamic movements.
CP365 can be applied at a whole range of ambient and substrate temperatures (-10°C to +35°C) onto cementitious based screeds, concrete, filled bitumen/asphalt, metal, ceramic tile and wood substrates.
- Highly flexible with excellent crack-bridging characteristics even at extremely low temperatures (-30°C and below)
- Can be applied to vertical surfaces by addition of thixotropic additive
- Very high impact and puncture resistanceas well as chemical and abrasion resistance
- Withstands stress and movements in the substrate
- Based on PUMA technology - free from external plasticisers
Surface Preparation
- The area to be waterproofed must be dry, firm, solid and free of dust, fat and oil.
- Laitance and loose particles must be removed thoroughly (e.g. by shot blasting).
- Fats or oils as well as humidity can be removed, for example, by flame blasting.
- Before the application of CP365, a suitable primer, including sanding when appropriate, must be first applied.
- For further details, see our general preparation and application guidelines for TREMCO MMA waterproofing systems.
Mixing
- Prior to use CP365 must be carefully mixed to achieve a uniform distribution of the paraffin contained in the product.
CP365 is thoroughly mixed together with the CP510 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 use 250 g of catalyst per 25 kg pail
- at 20°C use 350 g of catalyst per 25 kg pail
- at 10°C use 600 g of catalyst per 25 kg pail
- at 0°C use 1000 g of catalyst per 25 kg pail
- Below 0°C use 1000 kg of catalyst per 25 kg pail
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
- CP365 is designed to be manually applied using a trowel or squeegee.
