Pentens T-200H UV Resistant Elastomeric PU Waterproofing Coating 20KG

Description
PENTENS T-200H is based on newly developed water-based polyurethane and acrylic polymers. It dramatically reduces solar heat absorption in either air-conditioned or non-air-conditioned buildings. It takes the majority of the heat load of a building’s skin and reduces temperatures to approximately that of outside shade.

Features
• Water-based polyurethane and acrylic polymers.
• Reduces solar heat absorption in either air-conditioned or non-air-conditioned buildings.
• Reduces temperatures to approximately that of outside shade.

Benefits
• High elongation.
• Can resist ponding water.
• Water-based, environmentally friendly.
• Air and UV protection.
• Easy-cleaning and weather resistant.
• Chemical resistance and waterproof.
• User-friendly, suitable to use on any surface.
• Adheres well over-aged, galvanized and metal roofs, wood, asphalt or aluminum coatings, polystyrene foam insulation, polyester plastic panels, precast flat concrete, and barrel cement tiles, and many roofing materials.
• Prevention of ravages of acid rain, freeze-thaw, cycles, sunlight, bacteria, and fungus.
• Non-toxic.

Uses
PENTENS T-200H is a one-part elastomeric cross-linking latex copolymer emulsion designed as exposed waterproofing coating on:
• RC gutters and planter boxes
• Floor slabs
• Roof decks
• Wood siding / Fences
• External wall
• Flat roof
• Metal roof
• Concrete structures

Instruction of Use:
Surface Preparation
• Surface must be sound, dry, and clean (free from dirt, gravel, pollution, mildew, and all foreign material).
• Do not apply if any rain is imminent. Repair flashings and damaged areas.
• Cracks and old bitumen joints shall be repaired first.
• On existing surfaces must be thoroughly cleaned before applying PENTENS T-200H.
• Sweep and vacuum or power wash surface to remove dirt and dust.
• Cut out roof blisters and repair with acrylic embedded in polyester fabric or polymer concrete.
• Remove mildew with sodium hypochlorite or other algaecide and rinse with clean water.
• Fill any other gaps with silicon impregnated latex caulk.
• Any loose shingles should be gently lifted and glued down with roofing cement.

Application
• Substrate should be primed with a 1:3 mixture of PENTENS T-007 and clean water. Brush on at the approximate rate of 0.2~0.3kg/m².
• PENTENS T-200H is suggested to apply at least 2 coats.
• The first coat should be applied in one direction only.
• If possible the second coat should be applied at right angles to the first.
• Leave to cure for approximately 2 to 8 hours before applying second coat.
• PENTENS T-200H can be installed with conventional airless spray equipment, brush or roller.
• On areas exposed to hot drying winds, 2 to 3 thin coats of PENTENS T-200H may work better than 1 thick coat.

Important Notes
• Thoroughly agitate contents before use.
• Minimum ambient and substrate temperature is 5°C.
• Never apply more than 1kg/m² of PENTENS T-200H in one single layer.
• Apply only to clean and sound substrates where surfaces should be well dampened but free of surface water and leaks. 

Safety
PENTENS T-200H is non-toxic. For personal precautions, applicators are recommended to wear gloves and goggles when handling PENTENS T-200H.
