MPUTM 6MPA
Two Component Polyurethane Waterproofing Membrane
PRODUCT DESCRIPTION
MPUTM 6MPA is a two-component, high-strength,self-leveling, liquid applied, coal tar free polyurethane waterproofing membrane.
CHARACTERISTICS / ADVANTAGES
▪ Excellent physical and mechanical properties.
▪ Good bonding property, strong adhesion，the bonding strength is more than 2.5MPa.
▪ Good construction performance: two components mixed by a certain proportion and for use on-site,
▪ Excellent water and corrosion resistance
▪ Excellent low temperature flexibility: -35 ℃ low temperature bending without cracking,
▪ Environmental friendly.
▪ Meets the requirements of GB/T19250 and TB/T 2965
USES
Applied in the railway, highway, bridge, basement, sink, refrigerator, floors and other high requirements of waterproof engineering.
When applied to exposed surfaces, the use of the protective coating MPUTM TOP is required.

BASIS OF PRODUCT DATA
Results may differ based upon statistical variations depending upon mixing methods and equipment, temperature, application methods, test methods, actual site conditions and curing conditions.
LIMITATIONS
Higher temperatures and/or high humidity will accelerate the cure time. In cold weather conditions, use pail warmers or preconditioning to assist in work ability.
▪ Containers that have been opened must be used as soon as possible.
▪ Not recommended for light weight concrete, or asphalt surfaces.
▪ Do not apply to porous or damp surfaces where moisture vapor transmission will occur during application and cure. Exposure to direct sunlight can exacerbate vapor transmission during cure. Apply MPUTM 6MPA in shaded areas and/or during falling temperatures or contact Canlon for use of suitable primer in this situation.
▪Do not mix MPUTM 6MPA with water when using an airless sprayer.
▪ MPUTM 6MPA must not be submerged or subject to ponding water.
▪ MPUTM 6MPA must not be exposed to sunlight or UV radiation for more than 14 days.
▪ All surfaces where MPUTM 6MPA is applied must be "sloped to drain" to prevent standing or ponding water.
• Do not apply to contaminated surfaces.
• Not to be used as an exposed or wearing surface.
• Use with adequate ventilation.
• Do not apply over a curing or forming oil compound.
ENVIRONMENTAL, HEALTH AND SAFETY
For further information and advice regarding transportation, handling, storage and disposal of chemical products, user should refer to the actual Safety Data Sheets containing physical, environmental, toxicological and other safety related data. User must read the current actual Safety Data Sheets before using any products.
APPLICATION INSTRUCTIONS
SUBSTRATE PREPARATION
Surfaces may be dry or damp, but must be sound and free of standing water, dust, laitance, grease, curing compounds, impregnations, waxes and any other contaminants. Scratch and remove sheen for metal surfaces before applying primer. Scratch marine grade and high density plywood with sandpaper before applying primer.
MIXING
Before application, MPUTM 6MPA should be thoroughly mixed using a mechanical mixer and paddle at slow speed for 2 minutes minimum to ensure a homogeneous material. Take care not to allow entrapment of air into the material. Do not mix in an up and down motion.
APPLICATION
Priming: Some warranties and/or substrates may require the use of a primer.Substrates with moisture content > 4% should be primed with the special primer. Use the following primers accordingly: MPUTM402 for concrete.
Waterproofing:MPUTM 6MPA may be applied with a brush, squeegee, trowel, airless sprayer or roller in two layers. The first layer is applied 2-3 hours after priming and while MPUTM402 is still tacky. The second layer should be applied crosswise after 8-24 hours, depending on the weather conditions. In case there are dense, multiple cracks all over the surface, it is strongly recommended to fully reinforce MPUTM 6MPA membrane with some strips of polyester fleece (60 g/m2 ). These placed strips must overlap by 5-10 cm. In that case, 2-3 hours after priming, the first layer of MPUTM 6MPA is applied covering the reinforcement, while still fresh, a strip of polyester fleece is embedded. The same application process is followed over the remaining surface. Two extra layers of MPUTM 6MPA are applied over the entire surface. If waterproofing is done under the tiles,after the application of the final layer and while it is still fresh, quartz sand (Ø 0.3-0.8 mm) must be broadcast. The quartz sand must be completely dry.Apply up to 0.8mm horizontally per coat. Cured membrane must be intact after application to validate warranty.
Curing and Recoating: At 23 °C and 50 % relative humidity, allow each coat of MPUTM 6MPA to cure 16–24 hours minimum. If more than 48 hours pass between coats the surface must be solvent wiped and primed with MPUTM402 Primer.
Membrane Protection: As soon as possible after completion of a successful water test, visual inspection and/or repairs, cover membrane with an approved drainage mat or protection board. MPUTM 6MPA should not be exposed to sunlight or UV radiation for more than 14 days.
CLEANING OF TOOLS
Equipment should be immediately cleaned with an environmentally safe solvent, as permitted under local regulations.
LEGAL DISCLAIMER
• KEEP CONTAINER TIGHTLY CLOSED
• KEEP OUT OF REACH OF CHILDREN
• NOT FOR INTERNAL CONSUMPTION
• FOR INDUSTRIAL USE ONLY
• FOR PROFESSIONAL USE ONLY
